Background: This was a retrospective, large-sample, case-control study assessing the complications associated with synchronous microwave ablation (MWA) and biopsy for pulmonary sub-solid nodules or ground-glass nodules (GGNs) versus MWA alone. We aimed to verify the safety of synchronous MWA and biopsy for treating GGNs.
Methods: From May 2020 to December 2021, 326 patients with GGNs were enrolled. Among them, 164 patients underwent MWA alone (group A) and 162 patients underwent synchronous MWA and biopsy (group B). We assessed the complications, technical success, and positivity rate of the biopsy.
Results: The major complications were similar between the two groups, and included pneumothorax (group A vs. group B, 19.5% vs. 13.6%; P=0.150), hemothorax (0.6% vs. 1.2%; P=1.000), pleural effusion (1.2% vs. 0.6%; P=1.000), and pulmonary infection (4.9% vs. 6.2%; P=0.609). No massive hemoptysis, bronchopleural fistula, or air embolism developed. Minor complications including intrapulmonary hemorrhage (group A vs. group B, 28.7% vs. 62.3%, P<0.001), mild pneumothorax (20.7% vs. 29.6%, P=0.587), mild ipsilateral pleural effusion (30.5% vs. 27.8%, P=0.590), mild bilateral pleural effusion (16.5% vs. 22.2%, P=0.188), and subcutaneous emphysema (4.3% vs. 5.6%, P=0.498) were observed. The side effects, including pain, cough, post-ablation syndrome, and post-ablation chronic pain syndrome, were similar between the two groups. The positive diagnosis rate of biopsy in group B was 88.3%.
Conclusions: Compared with MWA alone, synchronous MWA and biopsy did not increase the risk of major complications. Although some minor complications developed, synchronous MWA and biopsy is safe for treating pulmonary GGNs.
背景:这是一项回顾性、大样本、病例对照研究,评估了同步微波消融(MWA)和活组织检查治疗肺实皮下结节或磨玻璃结节(GGNs)与单纯微波消融相比的并发症。我们旨在验证同步微波消融和活组织检查治疗GGNs的安全性:2020年5月至2021年12月,326名GGNs患者入组。其中,164 名患者单独接受了 MWA(A 组),162 名患者接受了同步 MWA 和活组织检查(B 组)。我们对并发症、技术成功率和活检阳性率进行了评估:两组患者的主要并发症相似,包括气胸(A 组对 B 组,19.5% 对 13.6%;P=0.150)、血胸(0.6% 对 1.2%;P=1.000)、胸腔积液(1.2% 对 0.6%;P=1.000)和肺部感染(4.9% 对 6.2%;P=0.609)。没有出现大咯血、支气管胸膜瘘或空气栓塞。观察到的轻微并发症包括肺内出血(A 组对 B 组,28.7% 对 62.3%,Pvs. 29.6%,P=0.587)、轻度同侧胸腔积液(30.5% 对 27.8%,P=0.590)、轻度双侧胸腔积液(16.5% 对 22.2%,P=0.188)和皮下气肿(4.3% 对 5.6%,P=0.498)。两组患者的副作用相似,包括疼痛、咳嗽、消融术后综合征和消融术后慢性疼痛综合征。B组活检阳性诊断率为88.3%:结论:与单纯 MWA 相比,同步 MWA 和活组织检查不会增加主要并发症的风险。结论:与单纯 MWA 相比,同步 MWA 和活组织检查不会增加主要并发症的风险,虽然会出现一些轻微并发症,但同步 MWA 和活组织检查对治疗肺 GGNs 是安全的。

Background: Lung adenocarcinoma associated with cystic airspace (LACA) was once considered an uncommon manifestation of lung adenocarcinoma (LUAD), and understandings of it are limited; however, it is being observed more frequently in clinical practice. This study sought to assess the prevalence of LACA, and compare the high-resolution computed tomography (HRCT) features of LACA in patients with varying degrees of invasiveness.
Methods: This study retrospectively reviewed the HRCT scans of 1,525 patients with LUAD ≤3 cm in diameter at the Shanghai Chest Hospital between January 2016 and May 2016. Each nodule was examined to detect the presence of cystic airspace. Additionally, we analyzed the qualitative HRCT findings of the cystic airspaces, including the pattern, number, wall component density, distribution, inner surface, mural nodules, septa, and vessels passing through the cystic airspace using the Pearson χ2 test or Fisher's exact test as appropriate. We also analyzed the quantitative measurements, such as the cystic airspace diameter, wall thickness, and thin-wall proportion, using a one-way analysis of variance or the Kruskal-Wallis rank-sum test as appropriate.
Results: LACAs were observed on HRCT in 11.5% (176/1,525) of the patients, of whom 7.1% (36/505) had pure ground-glass nodules, 13.5% (112/830) had mixed ground-glass nodules, and 14.7% (28/190) had solid nodules (P=0.001). The surgical procedures for LACAs varied (P=0.012). The incidence of LACAs increased as nodule diameter and invasiveness increased (both P<0.001). Statistically significant differences were observed in the wall component density, distribution, septa, vessels passing through the cystic airspace, cystic airspace diameter, wall thickness, and thin-wall proportion among the preinvasive lesion (PL), minimally invasive adenocarcinoma (MIA), and invasive adenocarcinoma (IAC) groups (P<0.001, P=0.024, P=0.001, P=0.025, P=0.001, P<0.001, and P<0.001, respectively). Wall component density increased as invasiveness increased (P<0.001). Unlike those in the MIAs and IACs, cystic airspaces in PLs typically lacked septa (P=0.001, and P<0.001, respectively). The IACs had larger cystic airspace diameters than the PLs (6.5 vs. 3.7 mm) (P<0.001). The IACs also had thicker wall thickness (11.8 vs. 6.8 mm, 11.8 vs. 8.3 mm) (P<0.001, and P<0.001, respectively) and smaller thin-wall proportions (181.5° vs. 264.8°, 181.5° vs. 223.8°) (P<0.001, and P=0.039, respectively) than the PLs and MIAs.
Conclusions: The prevalence and characteristics of cystic airspaces on HRCT can be used to predict invasiveness in patients with LUADs ≤3 cm in diameter.
背景:伴囊性气腔的肺腺癌(LACA)曾一度被认为是肺腺癌(LUAD)的一种不常见表现,人们对它的了解也很有限;然而,临床实践中却越来越频繁地观察到它。本研究旨在评估 LACA 的发病率,并比较不同侵犯程度患者的高分辨率计算机断层扫描(HRCT)特征:本研究回顾性分析了2016年1月至2016年5月期间上海胸科医院1525例直径≤3厘米的LUAD患者的HRCT扫描结果。我们对每个结节进行了检查,以检测是否存在囊性气腔。此外,我们还对囊性气腔的 HRCT 定性结果进行了分析,包括囊性气腔的形态、数量、壁成分密度、分布、内表面、壁结节、隔膜和穿过囊性气腔的血管,并酌情使用 Pearson χ2 检验或 Fisher's exact 检验。我们还根据情况采用单因素方差分析或 Kruskal-Wallis 秩和检验对囊腔直径、壁厚和薄壁比例等定量指标进行了分析:11.5%(176/1,525)的患者在 HRCT 上观察到 LACAs,其中 7.1%(36/505)为纯磨玻璃结节,13.5%(112/830)为混合磨玻璃结节,14.7%(28/190)为实性结节(P=0.001)。LACA的手术方式各不相同(P=0.012)。随着结节直径和侵袭性的增加(Pvs.均为 3.7 mm)(Pvs.6.8 mm, 11.8 vs. 8.3 mm)(Pvs.264.8°, 181.5° vs. 223.8°),LACAs 的发生率也随之增加(PConclusions:HRCT上囊性气腔的发生率和特征可用于预测直径≤3厘米的LUAD患者的侵袭性。

Background: Breast cancer is one of the most common malignancies in women worldwide, and early and accurate diagnosis is crucial for improving treatment outcomes. Conventional ultrasound (CUS) is a widely used screening method for breast cancer; however, the subjective nature of interpreting the results can lead to diagnostic errors. The current study sought to estimate the effectiveness of using a GoogLeNet deep-learning convolutional neural network (CNN) model to identify benign and malignant breast masses based on CUS.
Methods: A literature search was conducted of the Embase, PubMed, Web of Science, Wanfang, China National Knowledge Infrastructure (CNKI), and other databases to retrieve studies related to GoogLeNet deep-learning CUS-based models published before July 15, 2023. The diagnostic performance of the GoogLeNet models was evaluated using several metrics, including pooled sensitivity (PSEN), pooled specificity (PSPE), the positive likelihood ratio (PLR), the negative likelihood ratio (NLR), the diagnostic odds ratio (DOR), and the area under the curve (AUC). The quality of the included studies was evaluated using the Quality Assessment of Diagnostic Accuracy Studies Scale (QUADAS). The eligibility of the included literature were independently searched and assessed by two authors.
Results: All of the 12 studies that used pathological findings as the gold standard were included in the meta-analysis. The overall average estimation of sensitivity and specificity was 0.85 [95% confidence interval (CI): 0.80-0.89] and 0.86 (95% CI: 0.78-0.92), respectively. The PLR and NLR were 6.2 (95% CI: 3.9-9.9) and 0.17 (95% CI: 0.12-0.23), respectively. The DOR was 37.06 (95% CI: 20.78-66.10). The AUC was 0.92 (95% CI: 0.89-0.94). No obvious publication bias was detected.
Conclusions: The GoogLeNet deep-learning model, which uses a CNN, achieved good diagnostic results in distinguishing between benign and malignant breast masses in CUS-based images.

Background: Differential diagnosis in radiology relies on the accurate identification of imaging patterns. The use of large language models (LLMs) in radiology holds promise, with many potential applications that may enhance the efficiency of radiologists' workflow. The study aimed to evaluate the efficacy of generative pre-trained transformer (GPT)-4, a LLM, in providing differential diagnoses in neuroradiology, comparing its performance with board-certified neuroradiologists.
Methods: Sixty neuroradiology reports with variable diagnoses were inserted into GPT-4, which was tasked with generating a top-3 differential diagnosis for each case. The results were compared to the true diagnoses and to the differential diagnoses provided by three blinded neuroradiologists. Diagnostic accuracy and agreement between readers were assessed.
Results: Of the 60 patients (mean age 47.8 years, 65% female), GPT-4 correctly included the diagnoses in its differentials in 61.7% (37/60) of cases, while the neuroradiologists' accuracy ranged from 63.3% (38/60) to 73.3% (44/60). Agreement between GPT-4 and the neuroradiologists, and among the neuroradiologists was fair to moderate [Cohen's kappa (kw) 0.34-0.44 and kw 0.39-0.54, respectively].
Conclusions: GPT-4 shows potential as a support tool for differential diagnosis in neuroradiology, though it was outperformed by human experts. Radiologists should remain mindful to the limitations of LLMs, while harboring their potential to enhance educational and clinical work.

Background: Metal structures are a source of artifacts that significantly complicate the interpretation of magnetic resonance imaging (MRI). The use of prostate MRI as a preliminary test in men with a suspicion on prostate cancer leads to an increased use of the test. The aim of this study was to solve a clinically significant problem: to ensure the reduction of artifacts from metal hip implants during prostate MRI. Another goal was to evaluate the impact of artifact reduction methods on quantitative measurements.
Methods: The prostate gland (PG) phantom model was a cylinder filled with an aqueous solution of polyvinylpyrrolidone at the concentrations of 40%, 30%, and 20% [central zone (CZ), peripheral zone (PZ), and "lesion", respectively]. Phantom MRI study was conducted on Philips Ingenia 1.5T and Philips Ingenia 3T scanners.
Results: For 1.5 T, the reduction in the influence of artifacts inside region of interest (ROI) was observed, expressed in a decrease in the average apparent diffusion coefficient (ADC) (CZ, PZ, "lesion") for the manual artifact reduction (MAR) and ZOOM (title of software artifact reduction) techniques compared to the standard method. For 3T this effect was not detected. The same ADC results were obtained for Standard and MAR techniques, and increased ADC values for ZOOM. Despite the fact that the spread of ADC values on 3.0T scanners was minimal, there was a significant deviation of ADC values from the reference ones (up to 30.4%). Therefore, it is necessary to use a correction coefficient in the ADC calculation for the 3.0 T device. In the presented clinical case, high-quality tomograms were obtained without any artifacts, despite the presence of two hip replacement devices in the scanning area.
Conclusions: The accurate prostate MRI in the presence of implants is essential for an accurate diagnosis. This approach allows to reduce artifacts from hip implants, to visualize PG and periprostatic tissue in the best way, and to detect malignant and benign changes.
