Cor triatriatum sinister is a rare entity characterized by a membrane within the left atrium and posterior to the atrial appendage. This defect may cause obstructive symptoms analogous to mitral stenosis. The authors present a case of an incidentally detected enhancing mass originating from a cor triatriatum sinister membrane, with imaging characteristics most suggestive of myxoma. Keywords: MR Imaging, Cardiac, Left Atrium, Congenital, CT Angiography, Echocardiography Supplemental material is available for this article.

Purpose To investigate the feasibility and interscan variability of short-time cardiac MRI protocol after chemotherapy in individuals with breast cancer. Materials and Methods A total of 13 healthy female controls (mean age, 52.4 years ± 13.2 [SD]) and 85 female participants with breast cancer (mean age, 51.8 years ± 9.9) undergoing chemotherapy prospectively underwent routine breast MRI and short-time cardiac MRI using a 3-T scanner with peripheral pulse gating in the prone position. Interscan, intercoil, and interobserver reproducibility and variability of native T1 and extracellular volume (ECV), as well as ventricular functional parameters, were measured using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), or coefficient of variation (CoV). Results Left ventricular functional parameters had excellent interscan reproducibility (ICC ≥ 0.80). Left ventricular ejection fraction showed low interscan variability in control and chemotherapy participants (SEM, 2.0 and 1.2; CoV, 3.1 and 1.9, respectively). Native T1 showed excellent interscan (ICC, 0.75) and intercoil (ICC, 0.81) reproducibility in the control group and good interscan reproducibility (ICC, 0.72 and 0.73, respectively) in the participants undergoing immediate and remote chemotherapy. Interscan reproducibility for ECV was excellent in the control group and in the remote chemotherapy group (ICC, 0.93 and 0.88, respectively) and fair in the immediate chemotherapy group (ICC, 0.52). In the regional analysis, interscan repeatability and variability of native T1 and ECV were superior in the anteroseptum or inferoseptum than in other segments in the immediate chemotherapy group. Native T1 and ECV had good to excellent interobserver agreement across all groups. Conclusion Short-time cardiac MRI showed excellent results for interscan, intercoil, and interobserver reproducibility and variability for ventricular functional or tissue characterization parameters, suggesting that this modality is feasible for routine surveillance of cardiotoxicity evaluation in individuals with breast cancer.

Thin-Section CT in the Categorization and Management of Pulmonary Fibrosis including Recently Defined Progressive Pulmonary Fibrosis. 薄层 CT 在肺纤维化(包括最近定义的进行性肺纤维化)分类和管理中的应用。

While idiopathic pulmonary fibrosis (IPF) is the most common type of fibrotic lung disease, there are numerous other causes of pulmonary fibrosis that are often characterized by lung injury and inflammation. Although often gradually progressive and responsive to immune modulation, some cases may progress rapidly with reduced survival rates (similar to IPF) and with imaging features that overlap with IPF, including usual interstitial pneumonia (UIP)-pattern disease characterized by peripheral and basilar predominant reticulation, honeycombing, and traction bronchiectasis or bronchiolectasis. Recently, the term progressive pulmonary fibrosis has been used to describe non-IPF lung disease that over the course of a year demonstrates clinical, physiologic, and/or radiologic progression and may be treated with antifibrotic therapy. As such, appropriate categorization of the patient with fibrosis has implications for therapy and prognosis and may be facilitated by considering the following categories: (a) radiologic UIP pattern and IPF diagnosis, (b) radiologic UIP pattern and non-IPF diagnosis, and (c) radiologic non-UIP pattern and non-IPF diagnosis. By noting increasing fibrosis, the radiologist contributes to the selection of patients in which therapy with antifibrotics can improve survival. As the radiologist may be first to identify developing fibrosis and overall progression, this article reviews imaging features of pulmonary fibrosis and their significance in non-IPF-pattern fibrosis, progressive pulmonary fibrosis, and implications for therapy.

虽然特发性肺纤维化(IPF)是最常见的肺纤维化疾病,但还有许多其他原因导致的肺纤维化,其特征通常是肺损伤和炎症。虽然肺纤维化通常是逐渐进展的,对免疫调节也有反应,但有些病例可能进展迅速,存活率降低(与 IPF 相似),影像学特征与 IPF 重叠,包括以周围和基底侧网状结构、蜂窝状、牵引性支气管扩张或支气管扩张为特征的寻常间质性肺炎(UIP)模式疾病。最近,进行性肺纤维化一词被用来描述非 IPF 肺部疾病,这种疾病在一年内会出现临床、生理和/或放射学进展,并可能接受抗纤维化治疗。因此,对肺纤维化患者进行适当的分类对治疗和预后都有影响,可通过考虑以下分类:(a) 放射性 UIP 模式和 IPF 诊断,(b) 放射性 UIP 模式和非 IPF 诊断,以及 (c) 放射性非 UIP 模式和非 IPF 诊断。通过注意到纤维化的加重,放射科医生可以帮助选择使用抗纤维化药物治疗的患者,从而提高患者的生存率。由于放射科医生可能最先发现正在发展的肺纤维化和整体进展,本文回顾了肺纤维化的影像学特征及其在非 IPF 型肺纤维化、进展性肺纤维化中的意义以及对治疗的影响。关键词:特发性肺纤维化特发性肺纤维化 进行性肺纤维化 薄层 CT 通常间质性肺炎 © RSNA, 2024.

Purpose To develop a new coronary CT angiography (CCTA)-based index, α×LL/MLD4, that considers lesion entrance angle (α) in addition to lesion length (LL) and minimal lumen diameter (MLD) and to evaluate its efficacy in predicting hemodynamically significant coronary stenosis compared with invasive coronary angiography (ICA)-derived fractional flow reserve (FFR). Materials and Methods This prospective study enrolled participants (September 2016-March 2020) from two centers who underwent CCTA followed by ICA (ClinicalTrials.gov identifier: NCT03054324). CCTA images were processed semiautomatically to measure LL, MLD, and α for calculating α×LL/MLD4. Diagnostic performance and accuracy of α×LL/MLD4 and LL/MLD4 in detecting hemodynamically significant coronary stenosis were compared against the reference standard (invasive FFR ≤ 0.80). Results In total, 133 participants (mean age, 63 years ± 9 [SD]; 99 [74%] men) with 210 stenosed coronary arteries were analyzed. Median α×LL/MLD4 was 54.0 degree/mm3 (IQR, 25.3-128.7) in participants with invasive FFR of 0.80 or less and 6.7 degree/mm3 (IQR, 3.3-12.8) in participants with invasive FFR of more than 0.80 (P < .001). The per-vessel accuracy, sensitivity, specificity, positive predictive value, and negative predictive value for discriminating ischemic lesions were 86.2%, 83.1%, 88.4%, 84.1%, and 87.7% for α×LL/MLD4 and 80.5%, 66.3%, 90.9%, 84.3%, and 78.6% for LL/MLD4, respectively. Area under the receiver operating characteristic curve for discriminating hemodynamically significant stenosis was 0.93 for α×LL/MLD4, which was significantly greater than the values of 0.84 for LL/MLD4 and 0.63 for diameter stenosis (both P < .001). Conclusion The new morphologic index, α×LL/MLD4, incorporating lesion entrance angle achieved higher diagnostic performance in detecting hemodynamically significant lesions compared with diameter stenosis and LL/MLD4.

目的 开发一种基于冠状动脉 CT 血管造影 (CCTA) 的新指数 α×LL/MLD4,该指数除考虑病变长度 (LL) 和最小管腔直径 (MLD) 外,还考虑病变入口角 (α),并评估其与有创冠状动脉造影 (ICA) 得出的分数血流储备 (FFR) 相比在预测血流动力学显著性冠状动脉狭窄方面的疗效。材料和方法 这项前瞻性研究招募了来自两个中心的参与者(2016 年 9 月至 2020 年 3 月),他们都接受了 CCTA 检查,然后进行了 ICA(ClinicalTrials.gov 识别码:NCT03054324)。对 CCTA 图像进行半自动处理,测量 LL、MLD 和 α,以计算 α×LL/MLD4。将α×LL/MLD4 和 LL/MLD4 在检测血流动力学显著性冠状动脉狭窄方面的诊断性能和准确性与参考标准(有创 FFR ≤ 0.80)进行比较。结果 共分析了 133 名参试者(平均年龄 63 岁 ± 9 [SD];99 [74%] 男性)的 210 支狭窄冠状动脉。有创 FFR 为 0.80 或以下的参与者的中位 α×LL/MLD4 为 54.0 度/mm3(IQR,25.3-128.7),有创 FFR 为 0.80 以上的参与者的中位 α×LL/MLD4 为 6.7 度/mm3(IQR,3.3-12.8)(P < .001)。α×LL/MLD4的每血管准确性、敏感性、特异性、阳性预测值和阴性预测值分别为86.2%、83.1%、88.4%、84.1%和87.7%,LL/MLD4的准确性、敏感性、特异性、阳性预测值和阴性预测值分别为80.5%、66.3%、90.9%、84.3%和78.6%。α×LL/MLD4判别血流动力学显著狭窄的接收者操作特征曲线下面积为0.93,明显高于LL/MLD4的0.84和直径狭窄的0.63(P均<0.001)。结论 与直径狭窄和 LL/MLD4 相比,包含病变入口角的新形态学指标 α×LL/MLD4 在检测有血流动力学意义的病变方面具有更高的诊断性能。关键词CT 血管造影 心脏 冠状动脉 缺血 梗死 技术评估 临床试验注册号NCT03054324 本文有补充材料。© RSNA, 2023 另请参阅本期 Fairbairn 和 Nørgaard 的评论。
