Purpose
To evaluate ferumoxytol-enhanced magnetic resonance angiography (FE-MRA) for assessment of endoleaks in patients with abdominal aortic aneurysms (AAA) and chronic kidney disease (CKD) status post endovascular aneurysm repair (EVAR).
Methods
Of 1854 patients who underwent FE-MRA at a single institution between 03/21/2014 and 08/21/2023, 21 patients with a history of AAA and CKD status post EVAR were retrospectively identified (IRB #13-001341). Multiplanar pre- and post-contrast HASTE, T1-VIBE, and high-resolution breath-held 3D MRA sequences were obtained, where a dose of 4 mg/kg of Ferumoxytol was infused over six minutes. All examinations were performed on either a Siemens 3.0 T Prisma Fit, a Siemens 3.0 T TIM Trio, or a Siemens 1.5 T Avanto MRI scanner. Image post-processing was performed using OsiriX and Vitrea software for endoleak identification and display.
Results
Twenty-six FE-MRA examinations were completed, where 24 were fully diagnostic and 2 were limited by metal artifact. Three patients underwent one follow-up examination, while one patient underwent two follow-up examinations. Endoleaks were identified in seven patients: one Type Ia, two Type Ib, and four Type II. The Type Ia endoleak patient received follow-up imaging two years after initial imaging. A Type II endoleak patient received follow-up imaging six months and one year after initial imaging. In both cases, the Type I and Type II endoleaks were reproducibly visualized. No contrast reactions occurred.
Conclusion
For patients with a history of AAA and CKD status post EVAR, FE-MRA is a safe, practical and effective imaging solution for evaluation of Type I and Type II endoleaks.
目的：评估铁氧体增强磁共振血管造影（FE-MRA）在评估腹主动脉瘤（AAA）患者内漏和血管内动脉瘤修补术（EVAR）后慢性肾病（CKD）状态方面的应用：在2014年3月21日至2023年8月21日期间，在一家机构接受FE-MRA检查的1854名患者中，回顾性地确定了21名有AAA病史和EVAR术后有慢性肾脏病（CKD）的患者（IRB #13-001341）。在六分钟内输注 4 毫克/千克 Ferumoxytol 的剂量后，获得了多平面对比前后 HASTE、T1-VIBE 和高分辨率呼吸保持三维 MRA 序列。所有检查均在西门子 3.0 T Prisma Fit、西门子 3.0 T TIM Trio 或西门子 1.5 T Avanto MRI 扫描仪上进行。使用 OsiriX 和 Vitrea 软件进行图像后处理，以识别和显示内漏：完成了 26 次 FE-MRA 检查，其中 24 次完全确诊，2 次受到金属伪影的限制。三名患者接受了一次随访检查，一名患者接受了两次随访检查。在七名患者中发现了内漏：一名 Ia 型，两名 Ib 型，四名 II 型。Ia 型内漏患者在初次成像两年后接受了随访成像。一名 II 型内漏患者在初次成像六个月和一年后接受了随访成像。在这两个病例中，Ⅰ型和Ⅱ型内漏均可重复观察到。结论：对于 EVAR 后有 AAA 病史和 CKD 状态的患者，FE-MRA 是评估 I 型和 II 型内漏的一种安全、实用和有效的成像解决方案。

This letter responds to the article “Encouragement vs. liability: How prompt engineering influences ChatGPT-4's radiology exam performance,” offering additional perspectives on optimising ChatGPT-4 for Radiology applications. While the study highlights the significance of prompt engineering, we suggest that addressing additional key challenges such as age-related diagnostic needs, socio-economic diversity, data security, and liability concerns is essential for responsible AI integration. Incorporating adaptive prompts, training the model on diverse datasets, and securely integrating it with electronic health records (EHRs) can enhance its reliability and inclusiveness. By balancing prompt design with privacy and accountability frameworks, ChatGPT-4 can become a more effective tool in radiology, aiding clinicians without compromising human oversight.

To investigate differences in left ventricular wall thickness (LVWT) measurements between end-diastole and mid-diastole using cardiac computed tomography (CCT) and establish LVWT reference values stratified by phase, sex, and region.
Methods
Subjects who underwent CCT without a history of cardiovascular disease or risk factors were retrospectively included between 2021 and 2024. LVWT was manually measured in each segment according to the American Heart Association's 17-segment model at end-diastole and mid-diastole. Regional LVWT was calculated as the average value of relevant segments.
Results
The study included 187 subjects with a mean age of 51 ± 11 years, including 77 (41 %) men. Global LVWT was lower at end-diastole than at mid-diastole (5.7 ± 0.8 vs. 6.5 ± 0.9 mm, P < 0.001). Each segmental LVWT correlated significantly between end-diastole and mid-diastole (Pearson's correlation coefficient: 0.79–0.87). Segment 2 was thickest (8.1 ± 1.5 mm at end-diastole and 9.1 ± 1.7 mm at mid-diastole). LVWT was greater in men than in women (all P < 0.001). The upper limits of LVWT were 9.9 mm for women and 11.7 mm for men at end-diastole, and 11.8 mm for women and 13.1 mm for men at mid-diastole. LVWT progressively thinned from the base to the apex. Apical LVWT measured on short-axis and long-axis showed a small but statistically significant difference, particularly in Segment 16.
Conclusion
This study provides CCT reference values for LVWT at end-diastole and mid-diastole. Mid-diastolic LVWT was slightly greater than end-diastolic LVWT, with a statistically significant difference. Normal LVWT was greater in men than in women, with regional variations observed in both phases.
目的：利用心脏计算机断层扫描（CCT）研究舒张末期和舒张中期左室壁厚度（LVWT）测量的差异，并建立按阶段、性别和地区分层的LVWT参考值。方法：回顾性纳入2021年至2024年间无心血管疾病史或危险因素的CCT受试者。根据美国心脏协会舒张末期和舒张中期的17段模型，人工测量每段LVWT。区域LVWT计算为相关片段的平均值。结果：共纳入187例患者，平均年龄51±11岁，其中男性77例（41%）。整体LVWT在舒张末期低于舒张中期（5.7±0.8 vs 6.5±0.9 mm， P）。结论：本研究提供了舒张末期和舒张中期LVWT的CCT参考值。舒张中期LVWT略大于舒张末期LVWT，差异有统计学意义。正常LVWT在男性中大于女性，在两个阶段观察到区域差异。

This retrospective study aimed to assess ossification patterns and synchondrosis fusion timelines of the C1 and C2 vertebrae in pediatric age group, to help differentiate injuries from normal variations and serve as a guide when evaluating incompletely fused synchondrosis.
Materials and methods
The study analyzed 432 CT examinations of children aged 0–72 months, conducted at a single institution between January 2010 and January 2018. The focus was assessment of the visibility and fusion of the three ossification centers and three synchondroses of the atlas, and six ossification centers and four synchondroses of the axis, based on age.
Results
Complete ossification of the anterior arch of the atlas was observed in 60.4 % of patients, increasing with age from 11.1 % in the 0–12 months age group to 97.3 % in the 61–72 months age group. Patency of the ventrolateral synchondrosis of the atlas decreased from 100 % in the 0–12 months age group to around 30 % in the 61–72 months age group. Subdental synchondrosis and neurocentral synchondrosis of the axis were patent in 47.0 % and 50.6 % of patients, respectively, both decreasing with age. The apicodental synchondrosis of the axis remained mostly patent (98.1 %). Overall, there was a trend of decreasing patency in synchondroses and increasing ossification with advancing age.
Conclusion
These findings provide a better understanding of normal ossification patterns and timelines, facilitating the accurate distinction between normal variations and traumatic injuries.

Rationale and objectives
To evaluate radiologists' perspectives regarding American Medical Association Category 1 Continuing Medical Education (Cat-1 CME) activities in private practice (PP) and teleradiology (TR), as well as American Board of Radiology Maintenance of Certification (ABR MOC) program participation status.
Materials and methods
An electronic survey informed by existing literature regarding physician Cat-1 CME use and opinions was distributed via email to a national radiology practice. The survey was open for seventeen days in 2023, with a single reminder. Statistical analysis was performed using Pearson Chi square hypothesis testing and logistic regression modeling.
Results
Response rate was 19.2 % (599/3112). Of the 588 ABR certified, 65.6 % (n = 386) of respondents participated in ABR MOC, 50.9 % (n = 299) were in TR and 43.4 % (n = 255) were in PP. PP was associated with a greater participation in the ABR MOC program than TR (p0.05). Format (42 %) and content/topic (35 %) were the most important reasons for CME selection. PP radiologists preferred live in person lectures 1.94 times over TR. ABR MOC participants were 1.82 times more likely to select “cost” as the most important reason for choosing a Cat-1 CME activity, had lower odds of agreeing that Cat-1 CME helped maintain and improve skills, and had lower odds of being satisfied with Cat-1 CME activities available.
Conclusion
TR and PP settings in addition to ABR MOC participation status are associated with differences in Cat-1 CME-related preferences and perspectives.

Purpose
Compare the reduction and recovery of breast cancer screening and diagnostic services in urban versus suburban communities during the COVID-19 pandemic to identify opportunities for advancing equitable breast cancer detection.
Methods
This retrospective cohort study used the Montage™ data mining system to analyze percent change in the number of screening and diagnostic mammograms, breast biopsies, and breast cancer diagnoses at a single mid-Atlantic institution with urban and suburban sites centered in and around Philadelphia, Pennsylvania from 1/1/2019 to 12/31/2022, with urban-suburban subset comparison from 1/1/2019 to 12/31/2021.
Results
In 2020, screening mammogram volume dropped 23.9 % at urban sites and 1.6 % at suburban sites while diagnostic mammogram volume decreased 26.4 % at urban and 21.4 % at suburban sites. In 2021, screening volume at urban and suburban sites was 2.6 % and 31.0 % greater than pre-pandemic levels, and diagnostic volume was 28.5 % and 16.9 % below pre-pandemic levels. That same year, the proportion of invasive ductal carcinoma at urban sites increased by 26.2 %. In 2022, screening volume at all sites surpassed pre-pandemic levels by 19.5 % while diagnostic volume remained 21.7 % less than pre-pandemic levels.
Conclusion
The COVID-19 pandemic disproportionately reduced breast cancer screening and diagnostic services in urban communities, who experienced slower recovery and increased invasive breast cancer in the subsequent year. Throughout our institution, screening mammograms surpassed pre-pandemic levels in 2021 and 2022 while diagnostic services remained below pre-pandemic levels through 2022. Considering these findings, we must improve access to breast cancer screening and diagnosis to mitigate the long-term consequences of the pandemic.
