Background

Traditional didactic methods in medical imaging education, predominantly reliant on static images (non-augmented, traditional PACS workflow that requires manual, unguided search and interpretation), consistently fail to bridge the theory-practice divide, contributing to high diagnostic error rates. While the integration of artificial intelligence (AI) with Picture Archiving and Communication Systems (PACS+AI) offers transformative potential, robust evidence quantifying its impact on longitudinal competency development remains scarce.

Objective

This study aims to quantitatively evaluate the efficacy of a cognitively optimized PACS+AI framework versus conventional PACS in enhancing radiology education across four critical domains: theoretical knowledge, clinical decision-making competencies, AI acceptance, and knowledge retention.

Methods

In a prospective single-blind randomized controlled trial (RCT), 110 medical imaging undergraduates were randomized to PACS+AI (n = 55) or standard PACS (n = 55) groups. Theoretical knowledge was assessed using validated item-bank assessments; clinical decision-making competencies were evaluated through lesion detection, anatomical localization, diagnostic accuracy, and report completeness; AI acceptance was measured using the Technology Acceptance Model (TAM); and knowledge retention was tracked through immediate, 1-month, and 3-month follow-up assessments. The PACS+AI framework provided three core cognitive support functions: automated lesion annotation, structured diagnostic prompting, and workflow-contextualized feedback.

Results

The PACS+AI group demonstrated significantly superior outcomes across all domains: theoretical knowledge retention was substantially higher (79.3 % vs. 19.7 % at 3 months, P < 0.001, d=1.95); clinical decision-making competencies showed progressive improvement with large effect sizes (Δ=12.4–18.1, all P < 0.001, d=1.88–2.48); AI acceptance scores were significantly elevated across all TAM constructs (all P < 0.001, d>1.9); and knowledge retention was maintained longitudinally with amplified effects over time.

Conclusion

The PACS+AI framework significantly enhances radiology education by optimizing cognitive load distribution, resulting in sustained knowledge retention, superior clinical decision-making competencies, and heightened AI acceptance. This integrated teaching model effectively bridges the gap between theory and practice, cultivates professionals adaptable to the artificial intelligence environment, and aligns with the core needs of the new generation of medical education.
医学影像教育中的传统教学方法主要依赖于静态图像(非增强的,传统的PACS工作流程,需要手动,无指导的搜索和解释),始终未能弥合理论与实践的鸿沟,导致高诊断错误率。虽然人工智能(AI)与图像存档和通信系统(PACS+AI)的集成提供了变革潜力,但量化其对纵向能力发展影响的有力证据仍然很少。本研究旨在定量评估认知优化的PACS+AI框架与传统PACS在四个关键领域(理论知识、临床决策能力、人工智能接受和知识保留)加强放射学教育方面的效果。方法采用前瞻性单盲随机对照试验(RCT),将110名医学影像专业本科生随机分为PACS+AI组(n = 55)和标准PACS组(n = 55)。采用有效的题库评估来评估理论知识;通过病变检测、解剖定位、诊断准确性和报告完整性评估临床决策能力;使用技术接受模型(TAM)测量人工智能接受度;通过即时、1个月和3个月的随访评估来跟踪知识保留情况。PACS+AI框架提供了三个核心认知支持功能:自动病变注释、结构化诊断提示和工作流上下文化反馈。结果PACS+AI组在所有领域都表现出显著的优势:理论知识保留率明显更高(3个月时79.3% % vs. 19.7 %,P <; 0.001,d=1.95);临床决策能力呈进行性改善,且效应量较大(Δ= 12.4-18.1, P均为 <; 0.001,d= 1.88-2.48);人工智能接受得分在所有TAM结构中显著升高(P均为 <; 0.001,d>1.9);随着时间的推移,知识保留在纵向上保持着放大效应。结论PACS+AI框架通过优化认知负荷分配,显著增强放射学教育,实现持续的知识保留、卓越的临床决策能力和更高的人工智能接受度。这种一体化的教学模式有效地弥合了理论与实践的差距,培养了适应人工智能环境的专业人才,符合新一代医学教育的核心需求。

Background

Accurate assessment of right ventricular (RV) size and function is critical for managing cardiac diseases but is challenged by the limitations of traditional echocardiography. Artificial intelligence (AI) models offer potential for improving RV assessment, yet their diagnostic accuracy remains uncertain. This systematic review and meta-analysis evaluates the diagnostic accuracy of AI models for predicting RV size and function, synthesizing performance metrics and assessing evidence quality.

Methods

Adhering to PRISMA guidelines, we searched 5 databases up to June 2025 using MeSH and Emtree terms for "Artificial Intelligence," "Right Ventricular Function," and "Right Ventricular Dysfunction." Two reviewers screened studies, extracted data and assessed quality using PROBAST+AI. Pooled estimates were calculated using STATA 18 with MIDAS and METADATA modules. Heterogeneity was explored via subgroup analyses, meta-regression, and sensitivity analyses. Publication bias was assessed using funnel plot.

Results

From 25 studies, 18 provided data for meta-analysis, yielding a pooled sensitivity of 0.85 (95 % CI: 0.73–0.92), specificity of 0.81 (95 % CI: 0.72–0.88), and AUROC of 0.89 (95 % CI: 0.86–0.92). High heterogeneity (I² = 71.63 % for sensitivity, 73.51 % for specificity) was partially explained by algorithm type and study country. The GRADE assessment indicated moderate certainty of evidence due to heterogeneity and bias in 25 % of studies.

Conclusion

AI models show promising diagnostic accuracy for RV assessment, but high heterogeneity and moderate evidence certainty necessitate cautious interpretation and further research.
背景:准确评估右心室(RV)的大小和功能对心脏疾病的治疗至关重要,但传统超声心动图的局限性对其提出了挑战。人工智能(AI)模型为改进RV评估提供了潜力,但其诊断准确性仍不确定。本系统综述和荟萃分析评估了人工智能模型在预测RV大小和功能、综合性能指标和评估证据质量方面的诊断准确性。方法按照PRISMA指南,使用MeSH和Emtree检索截至2025年6月的5个数据库中的“人工智能”、“右心室功能”和“右心室功能障碍”。两名审稿人筛选研究,提取数据并使用PROBAST+AI评估质量。使用带有MIDAS和METADATA模块的STATA 18计算汇总估计值。通过亚组分析、meta回归和敏感性分析探讨异质性。采用漏斗图评估发表偏倚。结果25项研究中,18项提供了荟萃分析的数据,合并敏感性为0.85(95 % CI: 0.73-0.92),特异性为0.81(95 % CI: 0.72-0.88), AUROC为0.89(95 % CI: 0.86-0.92)。高异质性(敏感性I²= 71.63 %,特异性I²= 73.51 %)部分由算法类型和研究国家解释。GRADE评估显示,在25% %的研究中,由于异质性和偏倚,证据具有中等确定性。结论人工智能模型对RV评估具有较好的诊断准确性,但异质性高,证据确定性不高,需要谨慎解释和进一步研究。

Introduction

Optimizing the diagnostic approach to thyroid nodules remains a crucial challenge. Ultrasound-based risk stratification systems such as EU-TIRADS have shown reasonable sensitivity and specificity. Therefore, we conducted a systematic review and meta-analysis to assess the diagnostic performance of Artificial Intelligence (AI) models in differentiating benign from malignant thyroid nodules on ultrasound data.

Methods

A comprehensive search of PubMed/MEDLINE, Scopus, and Web of Science was performed up to January 1, 2025. Eligible studies included patients with thyroid nodules undergoing ultrasound, where AI-based models were validated against cytological or histological findings. The AI algorithms were developed using different types of ultrasound-derived data, including B-mode images, radiomics features. Pooled sensitivity, specificity, and area under the curve (AUC) were estimated using a hierarchical summary receiver operating characteristic (HSROC) model.

Results

Twenty-seven studies comprising 146,332 patients and over 600,000 ultrasound images met inclusion criteria. Overall, pooled sensitivity was 87 % (95 % CI: 84–89 %) and specificity 83 % (95 % CI: 79–86 %). The summary operating point indicated a sensitivity of 88 % and specificity of 83 %, with an AUC of 91.9 % (95 % CI: 90.0–93.2 %). Although subgroup analysis suggested higher accuracy when cytology was used as the reference standard compared to histology, the mixed-effects meta-regression did not confirm a statistically significant association (p = 0.238 for sensitivity; p = 0.188 for specificity).

Conclusion

AI-based algorithms show excellent diagnostic performance in distinguishing benign from malignant thyroid nodules, with robust validation across external datasets. These findings support the potential integration of AI into clinical thyroid nodule management, although further multicenter, non-Asian, and histology-based studies are warrantee.

优化甲状腺结节的诊断方法仍然是一个关键的挑战。超声风险分层系统如EU-TIRADS显示出合理的敏感性和特异性。因此,我们进行了一项系统综述和荟萃分析,以评估人工智能(AI)模型在超声数据鉴别甲状腺结节良恶性方面的诊断性能。方法综合检索截至2025年1月1日的PubMed/MEDLINE、Scopus、Web of Science数据库。符合条件的研究包括接受超声检查的甲状腺结节患者,其中基于人工智能的模型与细胞学或组织学结果进行了验证。人工智能算法是使用不同类型的超声衍生数据开发的,包括b模式图像,放射组学特征。使用分级汇总接收者工作特征(HSROC)模型估计合并敏感性、特异性和曲线下面积(AUC)。结果27项研究,146332例患者,60多万张超声图像符合纳入标准。总体而言,合并敏感性为87 %(95 % CI: 84-89 %),特异性为83 %(95 % CI: 79-86 %)。总结操作点灵敏度为88 %,特异性为83 %,AUC为91.9 %(95 % CI: 90.0 ~ 93.2 %)。虽然亚组分析表明,与组织学相比,细胞学作为参考标准的准确性更高,但混合效应荟萃回归并没有证实统计学上显著的关联(p = 0.238敏感性;p = 0.188特异性)。结论基于人工智能的算法在区分甲状腺结节良恶性方面表现出优异的诊断性能,在外部数据集上具有鲁棒性验证。这些发现支持人工智能在临床甲状腺结节治疗中的潜在整合,尽管进一步的多中心、非亚洲和基于组织学的研究是有保证的。系统评价注册号prospero (CRD420251108149)

Purpose

The study aimed to identify independent predictors associated with paravalvular regurgitation (PVR) after self-expanding transcatheter aortic valve replacement (SE-TAVR) and to develop a dual-parameter risk stratification model.

Methods

This retrospective study enrolled 292 severe aortic stenosis patients underwent SE-TAVR. PVR severity was assessed pre-discharge. Multivariate logistic regression identified independent predictors of mild/moderate PVR, optimal cutoff values for significant anatomical parameters were determined using receiver operating characteristic (ROC) curve analysis. Patients were subsequently stratified into three risk groups based on these thresholds.

Results

Mild/moderate PVR occurred in 24.0 % of patients. Independent predictors included aortic annular perimeter (OR:1.067, P = 0.015), device landing zone calcific volume (OR:1.006 per 10 mm³, P = 0.025), and presence of sealing skirt (OR:0.412, P = 0.010). The combination of these predictors had a higher discriminative performance (AUC=0.779) than single predictors (P = 0.036, 0.007, and <0.001, respectively), with significant integrated discrimination improvement (integrated discrimination improvement=5.4–6.7 %, P < 0.001). ROC-derived thresholds (device landing zone calcific volume≥1240 mm³ and aortic annular perimeter≥77 mm) stratified patients into three risk groups with progressively increasing PVR incidence: Group A (neither elevate):8.4 %; Group B (either elevated):23.7 %; and Group C (both elevated):48.7 %. Pairwise comparisons confirming differences between Group A vs. B (P = 0.003) and Group B vs. C (P < 0.001). Sealing skirts significantly reduced PVR in Groups A (P = 0.042) but not in Group B and C (P = 0.082 and 0.342).

Conclusion

The dual-parameter model based on device landing zone calcification and aortic annular perimeter significantly enhances PVR risk stratification after SE-TAVR. The dual-threshold model provides a clinically actionable tool for pre-procedural risk stratification and personalized valve selection.
目的探讨经导管主动脉瓣置换术(SE-TAVR)后瓣旁反流(PVR)的独立预测因素,建立双参数风险分层模型。方法回顾性研究292例重度主动脉瓣狭窄患者行SE-TAVR。出院前评估PVR严重程度。多因素logistic回归确定轻度/中度PVR的独立预测因子,采用受试者工作特征(ROC)曲线分析确定重要解剖参数的最佳截止值。随后根据这些阈值将患者分为三个危险组。结果轻/中度PVR发生率为24.0 %。独立预测因素包括主动脉环周长(OR:1.067, P = 0.015)、器械着陆区钙化体积(OR:1.006 / 10 mm³,P = 0.025)和密封裙的存在(OR:0.412, P = 0.010)。这些预测因子组合比单一预测因子具有更高的判别性能(AUC=0.779) (P = 0.036,0.007和<;0.001),具有显著的综合判别改善(综合判别改善= 5.4-6.7 %,P <; 0.001)。roc衍生阈值(器械着陆区钙化体积≥1240 mm³,主动脉环周长≥77 mm)将PVR发病率逐渐增加的患者分为三个危险组:A组(均未升高):8.4 %;B组(任一升高):23.7 %;C组(均升高):48.7 %。两两比较证实了A组与B组(P = 0.003)和B组与C组(P <; 0.001)之间的差异。封裙显著降低了A组的PVR (P = 0.042),而B组和C组无显著降低(P = 0.082和0.342)。结论基于器械着陆区钙化和主动脉环周长的双参数模型可显著增强SE-TAVR术后PVR风险分层。双阈值模型为术前风险分层和个性化瓣膜选择提供了临床可操作的工具。

Methods

This retrospective study analyzed 902 CT scans (584 normal, 142 calculi, 66 cancers, 110 cystitis). An integrated pipeline was implemented, comprising: 1) automatic bladder segmentation using a 3D-UNet, 2) hybrid feature extraction combining 100 radiomics features and 256 deep features from a 3D convolutional autoencoder, 3) feature selection via variance thresholding and LASSO regression, and 4) final classification using an XGBoost classifier. The dataset was split into training (80 %) and validation (20 %) sets. Performance was evaluated using the area under the receiver operating characteristic curve (AUROC) with a one-vs-rest strategy for multi-class classification. Model stability was assessed via stratified five-fold cross-validation, and interpretability was analyzed with SHapley Additive exPlanations (SHAP).

Results

The framework achieved one-vs-rest AUROCs of 0.94 (95 % CI: 0.89–0.99) for calculi, 0.92 (0.85–0.99) for cancer, 0.90 (0.84–0.95) for normal bladder, and 0.83 (0.75–0.91) for cystitis. The micro-average AUROC for four-class discrimination was 0.94 (0.92–0.96). Binary normal/abnormal classification demonstrated stable performance across cross-validation folds (AUROC range: 0.89–0.92). SHAP analysis revealed that radiomic features dominated decisions for calculi/normal differentiation, while deep features were critical for distinguishing cancer and cystitis.

Conclusion

The proposed hybrid CT analysis framework achieves clinically relevant performance in the automated, multi-class classification of bladder pathologies, excelling particularly in calculi detection. The complementary roles of radiomic and deep features provide an interpretable diagnostic aid, demonstrating potential for integration into clinical workflows to support differential diagnosis.
目的开发一种结合非对比CT图像放射组学和深度学习特征的自动分析框架,用于膀胱病理的多类别分类。方法回顾性分析902例CT扫描(正常584例,结石142例,癌66例,膀胱炎110例)。实现了一个集成的管道,包括:1)使用3D- unet自动膀胱分割,2)结合100个放射组学特征和来自3D卷积自编码器的256个深度特征的混合特征提取,3)通过方差阈值和LASSO回归进行特征选择,4)使用XGBoost分类器进行最终分类。数据集被分成训练集(80 %)和验证集(20 %)。使用接收者工作特征曲线下面积(AUROC)对性能进行评估,并采用一对休息策略进行多类别分类。通过分层五重交叉验证评估模型稳定性,并使用SHapley加性解释(SHAP)分析可解释性。结果该框架的auroc为:结石0.94(95 % CI: 0.89-0.99),癌症0.92(0.85-0.99),正常膀胱0.90(0.84-0.95),膀胱炎0.83(0.75-0.91)。四类鉴别的微平均AUROC为0.94(0.92 ~ 0.96)。二元正常/异常分类在交叉验证折叠中表现稳定(AUROC范围:0.89-0.92)。SHAP分析显示,放射学特征主导了结石/正常分化的决定,而深部特征对区分癌症和膀胱炎至关重要。结论本文提出的混合CT分析框架在膀胱病理的自动、多类别分类中达到了临床相关的性能,尤其在结石检测方面表现突出。放射学和深部特征的互补作用提供了可解释的诊断辅助,展示了整合到临床工作流程以支持鉴别诊断的潜力。

Purpose

This study aimed to assess the prognostic significance of pretreatment CT-based body composition markers in patients with Hepatocellular carcinoma (HCC) treated with radioembolization.

Material and methods

Automated analysis of baseline CT scans was performed to retrospectively evaluate body composition (BCA) parameters in 198 patients from a prospective registry database, including skeletal muscle (SM) and bone (B) volumes. BCA parameters and ratios were dichotomized using a maximally selected log-rank approach. Kaplan-Meier and uni- (UVA) and multivariate (MVA) Cox-proportional-hazard ratio (HR) survival analyses were performed.

Results

The median survival time was 18.5 months. In UVA, lower BCLC stage, ≦ 70 years of age, normal serum albumin, non-elevated C-reactive protein, normal aspartate aminotransferase (ASAT), normal alkaline phosphatase, normal gamma-glutamyl transaminase (GGT), absence of portal vein thrombosis and various BCA parameters were statistically significant with the skeletal muscle to bone ratio (SM/B) demonstrating the strongest survival discrimination with a median survival of 23.6 months for high and 12.0 months for low SM/B (HR: 0.65, 95 %CI: 0.46–0.9; p = 0.0001). In MVA, SM/B, BCLC stage, ASAT, and GGT remained independently significant. Patients with higher SM/B ratios demonstrated a significantly higher disease control rate during the initial imaging follow-up after three months (74.4 % vs. 54.0 %, p = 0.017).

Conclusion

These findings suggest that fully automated, CT-based measurement of BCA parameters — particularly the SM/B ratio — can serve as an independent prognostic factor for survival and disease control in patients with Hepatocellular carcinoma (HCC) undergoing radioembolization. This could potentially facilitate the identification of patients who would benefit most from this treatment.
目的本研究旨在评估基于ct预处理的体成分标志物在肝细胞癌(HCC)放射栓塞治疗中的预后意义。材料和方法对基线CT扫描进行自动分析,从前瞻性注册数据库中回顾性评估198例患者的身体成分(BCA)参数,包括骨骼肌(SM)和骨(B)体积。BCA参数和比率使用最大选择的log-rank方法进行二分类。进行Kaplan-Meier、单因素(UVA)和多因素(MVA) Cox-proportional-hazard ratio (HR)生存分析。结果中位生存期为18.5个月。UVA中,低BCLC分期、≦ 70岁、血清白蛋白、c反应蛋白、谷草转氨酶(ASAT)、碱性磷酸酶、γ -谷氨酰转氨酶(GGT)、门静脉血栓形成及BCA各项参数正常均有统计学意义,骨骼肌与骨量比(SM/B)表现出最强的生存差异,高SM/B组中位生存为23.6个月,低SM/B组中位生存为12.0个月(HR: 0.65, 95 %CI:0.46 - -0.9; = 0.0001页)。在MVA中,SM/B、BCLC分期、ASAT和GGT保持独立显著。SM/B比值较高的患者在3个月后的初始影像学随访中疾病控制率明显较高(74.4 % vs. 54.0% %,p = 0.017)。这些研究结果表明,全自动、基于ct的BCA参数测量,特别是SM/B比值,可以作为肝细胞癌(HCC)放射栓塞患者生存和疾病控制的独立预后因素。这可能有助于识别从这种治疗中获益最多的患者。

Objective

To investigate the feasibility of using modified time-of-flight magnetic resonance venography (mTOF-MRV) to evaluate the anatomical variations of the internal iliac vein (IIV).

Methods

This retrospective study included 158 patients suspected of iliac vein compression syndrome (IVCS) who underwent pelvic mTOF-MRV between June 2021 and March 2024. Fourteen patients with post-thrombotic syndrome (PTS) were excluded, leaving 144 eligible patients (52 males, 92 females; mean age 53 ± 16 years). Two radiologists independently evaluated image quality using a 4-point scale and analyzed IIV anatomical features via multiplanar reconstruction (MPR), maximum intensity projection (MIP), and volume rendering (VR) techniques. Inter-observer agreement was assessed using Cohen’s kappa coefficient and intraclass correlation coefficient (ICC).

Results

Inter-observer agreement for image quality was good (K=0.893), and for objective measurements was excellent (ICC [95 % confidence interval]: 0.893 [0.845–0.941]). Four IIV anatomical variation types were identified: Type I (unilateral single IIV draining to ipsilateral CIV bilaterally, 30.56 %), Type II (one/both pelvic cavities with two IIVs draining to ipsilateral CIV, 55.56 %), Type III (one IIV draining to ipsilateral CIV and the other to contralateral CIV, 11.80 %), and Type IV (other variations, 2.08 %). Left CIV compression was the most common (86.11 %).

Conclusion

The mTOF-MRV clearly visualizes IIV anatomy and variations. The proposed classification system aids preoperative planning and postoperative hemodynamic evaluation for pelvic venous disorders.
目的探讨应用改良飞行时间磁共振静脉成像(mTOF-MRV)评价髂内静脉(IIV)解剖变异的可行性。方法本回顾性研究纳入了158例疑似髂静脉压迫综合征(IVCS)的患者,这些患者于2021年6月至2024年3月期间接受了盆腔mTOF-MRV。排除14例血栓形成后综合征(PTS)患者,留下144例符合条件的患者(男性52例,女性92例,平均年龄53 ± 16岁)。两名放射科医生使用4分制独立评估图像质量,并通过多平面重建(MPR)、最大强度投影(MIP)和体绘制(VR)技术分析iv解剖特征。采用Cohen’s kappa系数和类内相关系数(ICC)评估观察者间的一致性。结果观察者间图像质量一致性好(K=0.893),客观测量一致性好(ICC[95 %置信区间]:0.893[0.845-0.941])。确定了四种IIV解剖变异类型:I型(单侧单一IIV引流至同侧CIV, 30.56% %),II型(一个/两个盆腔有两个IIV引流至同侧CIV, 55.56% %),III型(一个IIV引流至同侧CIV,另一个引流至对侧CIV, 11.80% %)和IV型(其他变异,2.08 %)。左CIV压迫最为常见(86.11 %)。结论mTOF-MRV能清晰显示iv的解剖结构和变异。所提出的分类系统有助于盆腔静脉疾病的术前规划和术后血流动力学评估。

Purposes

To evaluate the diagnostic confidence in cerebral aneurysm embolization coil follow-up using the deep learning image reconstruction (DLIR) based virtual monoenergetic images (VMI) combined with metal artifact reduction (MAR) algorithm, with a focus on selecting the most optimal scheme.

Methods

A CTA database of 54 patients was prospectively assembled and reconstructed utilizing adaptive statistical iterative reconstruction-Veo(ASIR-V50 %), DLIR at medium and high levels (DLIR-M and H). VMIs were generated within the 40–140 keV range at 10 keV intervals, both with or without MAR. Objective parameters such as artifact index (AI), signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) were measured. Subjective evaluation was assessed according to the Likert scale scoring method. The post-embolization therapeutic efficacy was assessed by the aneurysm neck, parent artery, and postprocedural complications.

Results

Firstly, 80 keV to 90 keV provided the best objective and subjective scores for a balance between artifact reduction and vascular display. Secondly, the DLIR-H+MAR combination exhibited the highest CNR at 80 keV to 90 keV, while also receiving the best subjective scores. Moreover, the MAR group showed significantly smaller discrepancies in aneurysm neck length and bilateral parent artery diameters compared to the non-MAR group when compared to DSA (p < 0.001). Importantly, the MAR group demonstrated two cases of aneurysm recurrence, four cases of residual filling, ten cases of parent artery stenosis, and four cases of aneurysmal rupture that were undetected by the non-MAR group.

Conclusion

DLIR-H+MAR at 80 keV to 90 keV proved to be the optimal method for visualizing cerebral arteries and mitigating metal artifacts. Simultaneously, it significantly enhanced the efficacy assessment and complication detection of post-embolization aneurysm.
目的评价基于深度学习图像重建(DLIR)的虚拟单能图像(VMI)联合金属伪影还原(MAR)算法在脑动脉瘤栓塞线圈随访中的诊断置信度,选择最优方案。方法采用自适应统计迭代重建- veo (ASIR-V50 %)、DLIR中高水平(DLIR- m和H)对54例患者的CTA数据库进行前瞻性组装和重构。在40-140 keV范围内,以10 keV的间隔生成VMIs,有或没有mar。测量人工指标(AI)、信噪比(SNR)和噪声对比比(CNR)等客观参数。主观评价采用李克特量表评分法。栓塞后的治疗效果通过动脉瘤颈部、载动脉和术后并发症来评估。结果首先,80 至90 keV为伪影还原和血管显示之间的平衡提供了最佳的客观和主观评分。其次,DLIR-H+MAR组合在80 keV至90 keV之间表现出最高的CNR,同时也获得了最好的主观得分。此外,与DSA相比,MAR组在动脉瘤颈长度和双侧载动脉直径上的差异明显小于非MAR组(p <; 0.001)。重要的是,MAR组有2例动脉瘤复发,4例残余填充,10例载瘤动脉狭窄,4例动脉瘤破裂未被非MAR组发现。结论dlir - h +MAR在80 ~ 90 keV范围内是脑动脉显像和减轻金属伪影的最佳方法。同时,显著提高了栓塞后动脉瘤的疗效评估和并发症的发现。

Submucosal laryngeal lesions: A puzzling diagnostic conundrum 喉粘膜下病变:一个令人困惑的诊断难题
IF 2.9 Q3 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING Pub Date : 2026-06-01 Epub Date: 2026-02-05 DOI: 10.1016/j.ejro.2026.100735

Laryngeal mucosal masses are commonly squamous cell carcinomas, easily identified and biopsied on scope. In contrast, a submucosal laryngeal mass has a broad differential diagnosis, including benign and malignant epithelial and non-epithelial neoplasms as well as other non-neoplastic abnormalities including vascular malformations, infective or inflammatory pathologies, submucosal hematoma, rare depositional diseases such as amyloidosis, and other benign lesions such as laryngoceles. Due to a lack of visible mucosal abnormality, biopsy of these lesions are often challenging with higher rates of false negatives or inadequate sampling. Whilst radiological imaging features of submucosal laryngeal lesions may be non-specific, there are some lesions which may exhibit typical imaging features which could help radiologists to narrow the differential diagnosis and direct diagnostic workup and clinical management more effectively. In this article, we will illustrate a spectrum of submucosal laryngeal lesions, with an emphasis on helpful imaging features to help distinguish pathologies, and an overview of appropriate workup and management aspects which the radiologist needs to know to contribute effectively to patient care.
喉部粘膜肿块通常为鳞状细胞癌,在镜下容易识别和活检。相比之下,喉粘膜下肿块的鉴别诊断范围很广,包括良恶性上皮性和非上皮性肿瘤,以及其他非肿瘤性异常,包括血管畸形、感染或炎症病理、粘膜下血肿、罕见的沉积性疾病如淀粉样变性,以及其他良性病变如喉囊肿。由于缺乏可见的粘膜异常,这些病变的活检往往具有较高的假阴性率或取样不足的挑战性。虽然喉粘膜下病变的影像学特征可能不具有特异性,但也有一些病变可能表现出典型的影像学特征,这可以帮助放射科医生更有效地缩小鉴别诊断范围,指导诊断工作和临床管理。在这篇文章中,我们将说明喉粘膜下病变的频谱,重点是有用的影像特征,以帮助区分病理,并概述适当的检查和管理方面,放射科医生需要知道,以有效地促进患者护理。

Whilst radiological imaging features of submucosal laryngeal lesions may be non-specific, there are some lesions which may exhibit typical imaging features which could help radiologists to narrow the differential diagnosis and direct diagnostic workup and clinical management more effectively. In this article, we will illustrate a spectrum of submucosal laryngeal lesions, with an emphasis on helpful imaging features to help distinguish pathologies, and an overview of appropriate workup and management aspects which the radiologist needs to know to contribute effectively to patient care.</div></div>","PeriodicalId":38076,"journal":{"name":"European Journal of Radiology Open","volume":"16 ","pages":"Article 100735"},"PeriodicalIF":2.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146188338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective

To compare AI-augmented and conventional double reading in organised breast-cancer screening with respect to cancer-detection rate (CDR), recall rate, and radiologist workload.

Methods

We conducted a systematic review and random-effects meta-analysis of 13 prospective and retrospective studies (1.03 million screens) from 2017 to 2024 that embedded commercial or research AI into population-based digital mammography or tomosynthesis programmes. Eligible studies included ≥ 10,000 screens (or ≥100 cancers) and reported CDR, recalls, and/or workload metrics. We extracted cancer and recall counts and calculated risk ratios (RRs) for AI-augmented versus double reading, overall and by integration model: independent second reader, gate-keeper/decision-referral triage, and concurrent overlay.

Results

Overall, AI-augmented protocols achieved CDR parity (RR 1.01; 95 % CI 0.96–1.07) and no significant change in recalls (RR 1.00; 95 % CI 0.88–1.15). Triage models preserved CDR (RR 1.02; 95 % CI 0.98–1.07) while reducing recalls by 11 % (RR 0.89; 95 % CI 0.82–0.96) and cutting initial reads by 44–70 %. Independent-reader workflows maintained CDR (RR 0.98; 95 % CI 0.92–1.05) but showed variable recall effects (RR 1.12; 95 % CI 0.90–1.39) driven by arbitration logic and threshold choices. Concurrent overlay (two studies) indicated possible sensitivity gains (RR 1.31; 95 % CI 0.90–1.91) without higher recall rates, though precision was limited.

Conclusions

AI integration can match conventional double reading in detection performance, but its impact on workflow depends on the chosen model. Triage-based approaches consistently lower radiologist workload and recalls without compromising sensitivity, whereas replacing a second reader may simply shift effort to arbitration. Future implementation should focus on workflow-aware metrics and prospective threshold validation.
目的比较人工智能增强双读与常规双读在组织乳腺癌筛查中的癌症检出率、召回率和放射科医生工作量。方法:我们对2017年至2024年期间将商业或研究性人工智能嵌入基于人群的数字乳房x光检查或断层合成计划的13项前瞻性和回顾性研究(103万例筛查)进行了系统回顾和随机效应荟萃分析。符合条件的研究包括≥ 10,000个筛查(或≥100个癌症)和报告的CDR、召回和/或工作量指标。我们提取了癌症和召回计数,并计算了人工智能增强与双重读取的风险比(rr),总体上和通过集成模型:独立的第二读取器、看门人/决策-推荐分诊和并发叠加。结果总体而言,人工智能增强方案实现了CDR奇偶性(RR 1.01; 95% CI 0.96-1.07),召回率无显著变化(RR 1.00; 95% CI 0.88-1.15)。分诊模型保留了CDR (RR 1.02; 95% CI 0.98-1.07),同时减少了11%的召回(RR 0.89; 95% CI 0.82-0.96),并减少了44 - 70%的初始读数。独立读者工作流程保持CDR (RR 0.98; 95% CI 0.92-1.05),但在仲裁逻辑和阈值选择的驱动下显示出可变的召回效应(RR 1.12; 95% CI 0.90-1.39)。同时叠加(两项研究)表明可能的灵敏度提高(RR 1.31; 95% CI 0.90-1.91)没有更高的召回率,尽管精度有限。结论ai集成在检测性能上可与传统双读相媲美,但对工作流程的影响取决于所选择的模型。基于分诊的方法持续降低放射科医生的工作量和召回,而不影响灵敏度,而更换第二个阅读器可能只是将工作转移到仲裁。未来的实现应该关注工作流感知度量和预期阈值验证。
