Rationale and objectives

Gender diversity in academic medicine has increased over time, but it is unknown whether these trends vary by academic rank and tenure status in highly competitive specialties. The aim of this study was to analyze trends in gender representation among emergency medicine, radiology, ophthalmology, anesthesiology, and dermatology (E-ROAD) faculty.

Materials and methods

Publicly available data from the Association of American Medical Colleges (AAMC) Faculty Roster (1966–2021) were analyzed. Variables included gender and academic rank. Significance testing for 2-group comparisons was conducted via Mann Whitney U test.

Results

Representation of women increased steadily across all E-ROAD specialties and ranks. The largest shifts occurred among professors and tenured positions. From 2001 to 2021, women outnumbered men among assistant professors and instructors in dermatology. Faculty approached gender parity (man-to-woman ratio < 2) among associate professors in dermatology, assistant professors in all specialties except radiology, and instructors across all specialties. In dermatology, women outnumbered men across on-track, not-on-track, and tenure-unavailable positions. Faculty approached gender parity among on-track faculty in anesthesiology and ophthalmology, and among not-on-track faculty in all specialties except radiology. By 2021, men outnumbered women professors by 2.7 to 5.2-fold across E-ROAD specialties.

Conclusions

Representation of women increased significantly across all academic ranks and tenure statuses in E-ROAD specialties, with especially large gains in senior ranks. However, men continue to hold the majority of professor positions. Junior ranks and non-tenured positions approached gender parity in most specialties by 2021.

基本原理和目标医学学术中的性别多样性随着时间的推移而增加，但在高度竞争的专业中，这些趋势是否会随着学术级别和终身职位的不同而变化，这一点尚不清楚。本研究的目的是分析急诊科、放射科、眼科、麻醉科和皮肤科（E-ROAD）教师中性别代表性的趋势。材料和方法分析美国医学院协会（AAMC）教师名册（1966-2021）的公开数据。变量包括性别和学术等级。两组比较的显著性检验采用Mann Whitney U检验。结果在E-ROAD的所有专业和级别中，女性的比例稳步上升。变化最大的是教授和终身职位。从2001年到2021年，在皮肤病学助理教授和讲师中，女性的数量超过了男性。在皮肤科副教授、除放射学以外所有专业的助理教授和所有专业的讲师中，教员接近性别平等（男女比例<； 2）。在皮肤科，女性在在职、非在职和终身职位上的数量都超过了男性。麻醉学和眼科学在职教员以及除放射学以外的所有非在职教员都在努力实现性别平等。到2021年，在E-ROAD专业中，男性教授的数量是女性教授的2.7至5.2倍。结论：在E-ROAD专业的所有学术级别和终身职位中，女性的代表性显著增加，在高级职位中增幅尤其大。然而，男性仍然占据大多数教授职位。到2021年，大多数专业的初级职位和非终身职位接近性别平等。

Headcheese sign is a radiological sign seen on CT and is classically seen in hypersensitivity pneumonitis. The headcheese sign was coined by Patel Rita et al. (2000) based on the appearance of the savory meat dish headcheese. Its appearance is due to a mixture of three different attenuations in the lung which is also known as the three density sign. The mosaic pattern is characterized by the presence of ground glass opacities (higher attenuation), air trapping (decreased attenuation), and normal lung.

头干酪征是一种典型的超敏性肺炎的CT影像学征象。headcheese标志是由Patel Rita等人（2000）根据美味的肉菜headcheese的外观创造的。它的出现是由于肺部三种不同衰减的混合，也称为三密度征象。马赛克模式的特征是存在磨玻璃混浊（高衰减），空气捕获（衰减降低）和正常肺。

Breast complaints in children and adolescents are common, anxiety-provoking, and overwhelmingly benign. This educational review distills a practical approach for general, pediatric, and breast radiologists that emphasizes ultrasound-first imaging only when clinically indicated, focused history and examination, and judicious follow-up. We summarize normal pubertal development and common benign entities, outline red flags that warrant expedited assessment, and present stepwise algorithms for evaluation and management that balance diagnostic confidence with protection of the developing breast. Benign-appearing solid masses under 5 cm without worrisome sonographic features are typically observed with interval ultrasound, recognizing that spontaneous regression is common adolescents. Escalation is reserved for rapid growth, lesions ≥5 cm, classic suspicious features, or discordance between imaging and clinical findings; tissue sampling should be targeted, with careful attention to radiology–pathology concordance and sampling adequacy. We highlight pitfalls that mimic disease (e.g., normal pubertal tissue, gynecomastia) and provide structured reporting templates and checklists to standardize communication, reduce unnecessary intervention, and support counseling of patients and families. By consolidating current evidence and everyday experience into actionable guidance, this review aims to improve consistency, minimize harm, and streamline care for young patients presenting with breast symptoms.

儿童和青少年的乳房抱怨是常见的，令人焦虑的，而且绝大多数是良性的。这篇教育综述为普通、儿科和乳腺放射科医生提炼出一种实用的方法，强调只有在临床指征、重点病史和检查以及明智的随访时才进行超声优先成像。我们总结了正常的青春期发育和常见的良性实体，概述了需要快速评估的危险信号，并提出了评估和管理的逐步算法，以平衡诊断的信心和对发育中的乳房的保护。间隔超声通常观察到5厘米以下的良性实性肿块，无令人担忧的超声特征，认识到自发消退在青少年中很常见。升级诊断为快速增长、病变≥5cm、典型可疑特征或影像学与临床表现不一致；组织取样应该是有针对性的，仔细注意放射病理学的一致性和取样的充分性。我们强调了模仿疾病的陷阱（例如，正常的青春期组织，男性乳房发育症），并提供结构化的报告模板和清单，以规范沟通，减少不必要的干预，并支持患者和家属的咨询。通过将现有证据和日常经验整合为可操作的指导，本综述旨在提高一致性，减少危害，并简化对出现乳房症状的年轻患者的护理。

Women remain underrepresented in faculty leadership roles within medicine, despite growing representation and significant contributions across a wide range of specialties. This is especially true in the traditionally male-dominated field of radiology. While traditional mentorship has largely been endorsed as a tool for professional growth, recent research suggests mentorship alone is insufficient to address structural inequities in highly complex academic environments. Instead, sponsorship – or active advocacy by individuals in positions of power and influence – may be more beneficial to increase visibility, support, and access to opportunities for advancement.

This brief communication describes the American Association for Women in Radiology (AAWR) Sponsorship Circle, conducted during the 2025 American College of Radiology (ACR) Annual Meeting in Washington, DC. Twenty participants across career stages practiced articulating professional “asks,” received real-time feedback, and exchanged tangible offers of sponsorship.

Participants reported strengthened self-advocacy skills, expanded professional networks, and a heightened sense of community and belonging. The event demonstrated that even brief, well-structured interventions can catalyze career growth and foster a culture of mutual advocacy. Sponsorship circles provide a scalable model for accelerating women's career growth and leadership in academic radiology.

尽管女性在医学领域的代表性不断增加，并在广泛的专业领域做出了重大贡献，但女性在医学领域的领导地位仍然不足。在传统上以男性为主的放射学领域尤其如此。虽然传统的师徒关系在很大程度上被认为是一种专业成长的工具，但最近的研究表明，仅靠师徒关系不足以解决高度复杂的学术环境中的结构性不平等问题。相反，赞助——或有权力和影响力的个人的积极倡导——可能更有利于增加知名度、支持和获得晋升机会。这份简短的通讯描述了在华盛顿特区举行的2025年美国放射学会（ACR）年会上进行的美国妇女放射学协会（AAWR）赞助圈。20名不同职业阶段的参与者练习表达专业的“要求”，收到实时反馈，并交换切实的赞助提议。参与者报告说，他们的自我宣传技能得到了加强，专业网络得到了扩展，社区意识和归属感得到了增强。这次活动表明，即使是简短的、结构良好的干预也能促进职业发展，培养相互倡导的文化。赞助圈为加速女性在学术放射学中的职业发展和领导力提供了一个可扩展的模式。

Menstrual toxic shock syndrome (mTSS) is a rare, life-threatening condition mainly affecting young menstruating women. While the clinical and microbiological aspects of mTSS are well-documented, consolidated evidence on its radiologic findings remains limited in the literature. This study aimed to systematically review published case reports of mTSS to describe the spectrum of radiologic findings and assess the role of imaging in diagnosis and management.

A systematic search of Medline and Embase was conducted from the earliest available records to September 2024. Case reports were included if they described mTSS cases meeting CDC criteria and involved imaging in diagnosis or management. Twelve eligible reports were identified and analyzed for demographics, microbiology, imaging modality and findings, clinical course, and patient outcome.

Imaging was typically performed early during hospitalization and included CT, ultrasound, chest x-ray, and echocardiography. Pulmonary findings were most common, including bilateral infiltrates and features of acute respiratory distress syndrome (ARDS) or septic emboli. Abdominal and pelvic imaging revealed ascites, mesenteric edema, bowel wall thickening, and adnexal inflammation. Imaging also identified sources of infection, such as intrauterine devices, and guided management decisions such as drainage or ICU admission. In some cases, imaging was normal despite severe clinical presentations.

While radiologic findings are non-specific, their presence supports the clinical suspicion of mTSS and helps assess systemic complications. This review highlights the importance of early, multimodal imaging in patients with unexplained shock or fever, particularly in menstruating women, and emphasizes the need for interdisciplinary collaboration in managing this syndrome.

月经中毒性休克综合征（mTSS）是一种罕见的危及生命的疾病，主要影响年轻的月经妇女。虽然mTSS的临床和微生物方面有充分的记录，但其放射学发现的综合证据在文献中仍然有限。本研究旨在系统地回顾已发表的mTSS病例报告，以描述放射学表现的频谱，并评估成像在诊断和治疗中的作用。对Medline和Embase进行了系统检索，从最早的可用记录到2024年9月。病例报告如果描述的mTSS病例符合CDC标准，并在诊断或管理中涉及影像学，则纳入。确定并分析了12份符合条件的报告，包括人口统计学、微生物学、成像方式和结果、临床过程和患者预后。影像学通常在住院早期进行，包括CT、超声、胸部x线和超声心动图。肺部表现最常见，包括双侧浸润和急性呼吸窘迫综合征（ARDS）或脓毒性栓塞的特征。腹部和盆腔影像显示腹水、肠系膜水肿、肠壁增厚和附件炎症。影像学检查还可以识别感染源，如宫内节育器，并指导管理决策，如引流或ICU入院。在一些病例中，尽管有严重的临床表现，但影像学表现正常。虽然放射学的发现是非特异性的，但它们的存在支持了临床对mTSS的怀疑，并有助于评估全身并发症。这篇综述强调了对不明原因休克或发热患者，特别是经期妇女进行早期多模式影像学检查的重要性，并强调了在治疗这一综合征时需要跨学科合作。

Pulmonary nodules are among the most frequent findings on chest CT scans, creating challenges in balancing early detection with the avoidance of overdiagnosis. This brief communication compares the Fleischner Society 2017 and Lung-RADS 2022 guidelines for management of single solid nodules in high-risk adults. Although these guidelines are designed for distinct clinical contexts, high-risk individuals often undergo diagnostic CT scans outside screening pathways, resulting in variation in follow-up strategies and management. We conducted a focused comparative analysis of both systems, examining follow-up recommendations for solid nodules ≤5 mm, 8 mm, and ≥9 mm. Both systems mostly align for nodules ≤5 mm, while Lung-RADS recommends earlier PET/CT evaluation for nodules >8 mm and a higher threshold for biopsy than Fleischner. These differences can influence surveillance intensity, timing of diagnosis, and resource utilization when screening eligible patients undergo diagnostic CT outside structured LDCT programs. Recognizing that this ambiguity arises from clinical workflow rather than from conceptual conflict between guidelines may help radiologists apply each framework more appropriately and reduce uncertainty in high-risk patients encountered outside formal screening pathways.

肺结节是胸部CT扫描中最常见的发现之一，这给平衡早期发现和避免过度诊断带来了挑战。这篇简短的交流比较了Fleischner Society 2017和Lung-RADS 2022在高危成人单一实体结节管理方面的指南。尽管这些指南是针对不同的临床情况而设计的，但高风险个体经常在筛查途径之外进行诊断性CT扫描，从而导致随访策略和管理的变化。我们对两种系统进行了重点比较分析，研究了≤5mm、8mm和≥9mm的实性结节的随访建议。两种系统大多针对≤5mm的结节，而Lung-RADS建议对≤8mm的结节进行早期PET/CT评估，活检阈值高于Fleischner。当筛查符合条件的患者在结构化LDCT项目之外接受诊断性CT时，这些差异会影响监测强度、诊断时机和资源利用。认识到这种模糊性来自临床工作流程，而不是来自指南之间的概念冲突，可以帮助放射科医生更恰当地应用每个框架，并减少在正式筛查途径之外遇到的高风险患者的不确定性。

Background

High-frequency ultrasound (US) of the nail in pediatric psoriasis remains underexplored.

Objective

To describe nail US features and Power Doppler (PD) activity in children with psoriasis.

Methods

Cross-sectional study of 43 consecutive patients evaluated with an 18-MHz probe and sensitive PD settings. Recorded variables included nail plate irregularity, trilaminar pattern, Wortsman classification and distal extensor enthesis. Demographic and clinical characteristics and nail physical examination were also collected.

Results

US abnormalities were identified in 46.5% of children. PD activity was present in 37.2%, including nails without clinical changes. Trilaminar loss was observed in 4.7%, and classic Wortsman-type patterns were uncommon. No distal extensor enthesitis was detected. Descriptively, PD positivity was observed in both clinically normal and clinically altered nails, without formal hypothesis testing.

Conclusion

High-frequency nail US frequently reveals subclinical nail abnormalities in pediatric psoriasis, with PD signal in over one-third of patients and minimal entheseal involvement. These descriptive findings support the feasibility of pediatric nail ultrasound and highlight the need for pediatric-focused technical parameters and longitudinal controlled studies to clarify prognostic value.

背景：高频超声（US）在小儿牛皮癣指甲中的应用尚不充分。目的探讨小儿牛皮癣患者的甲US特征及功率多普勒（PD）活动。方法对43例连续患者进行横断面研究，采用18mhz探针和敏感PD设置进行评估。记录的变量包括甲板不规则性、三线形、Wortsman分类和远端伸肌内伸。同时收集患者的人口学、临床特征及指甲体格检查。结果46.5%的患儿存在sus异常。37.2%的患者有PD活动，包括无临床变化的指甲。4.7%的患者出现三椎体缺失，典型的wortsman型不常见。未发现远端伸肌发炎。描述性地，PD阳性在临床正常和临床改变的指甲中都被观察到，没有正式的假设检验。结论：小儿银屑病患者的高频指甲超声常显示亚临床指甲异常，超过三分之一的患者有PD信号，且极少累及骨骺。这些描述性研究结果支持儿科指甲超声的可行性，并强调需要以儿科为中心的技术参数和纵向对照研究来阐明预后价值。

Objective

The objective of this study was to assess trends in Molecular Breast Imaging (MBI) utilization among privately insured women in the United States (U.S.) from 2017 to 2022.

Methods

The utilization of MBI among women aged 25–64 years from January 1, 2017, to December 31, 2022, was obtained using the Merative MarketScan Commercial Database. MBI utilization was captured from the outpatient services file using Current Procedural Terminology (CPT) or Healthcare Common Procedure Coding System (HCPCS) codes for MBI.

Results

During the 6-year retrospective claims analysis, 3024 study-eligible women underwent 3648 MBI exams. The overall trend in MBI utilization was relatively stable from 2017 to 2021, with a 33% reduction in utilization in 2022. The lowest utilization rate was in 2022 at 5.6 per 1000 person-years of observation. Of the women who underwent MBI with sufficient follow-up, 83% underwent only one examination during the study period.

Conclusion

MBI is consistently underutilized during the study period despite its accuracy, affordability, and safety for diagnosing breast cancer.

目的：本研究的目的是评估2017年至2022年美国私人保险女性使用分子乳房成像（MBI）的趋势。方法：使用Merative MarketScan商业数据库获取2017年1月1日至2022年12月31日25-64岁女性使用MBI的情况。使用MBI的当前程序术语（CPT）或医疗保健通用程序编码系统（HCPCS）代码从门诊服务文件中捕获MBI的使用情况。结果：在6年的回顾性索赔分析中，3024名符合研究条件的女性接受了3648次MBI检查。从2017年到2021年，MBI利用率的总体趋势相对稳定，2022年的利用率下降了33%。最低的利用率是在2022年，每1000人年观察5.6人。在接受MBI并进行了充分随访的女性中，83%在研究期间只接受了一次检查。结论：在研究期间，尽管MBI诊断乳腺癌的准确性、可负担性和安全性较高，但其一直未得到充分利用。

Background

Hip dysplasia and cam morphology are both common causes of hip pain in pediatric patients. However, there is limited literature on how the presence of hip dysplasia may affect the prevalence of cam morphology.

Objective

This study aims to assess if hip dysplasia in pediatric patients has a similar prevalence and location of cam morphology compared with non-dysplastic hips.

Materials and methods

This retrospective study assessed pediatric patients with hip pain from April 2012 to June 2024. Data collection was based on chart review and imaging consensus review of all hip MRIs conducted by two musculoskeletal radiologists and a pediatric orthopedic surgeon. Data included were the presence of hip dysplasia, defined as a lateral center-edge angle (LCEA) <18°, cam morphology, and their location. Chi-square and Fisher's exact test were used with p-values for significance set to 0.05.

Results

From our study cohort of 118 hips in 107 patients (mean age 15.3. years, 66% female, 81 hips underwent surgery), there were 64 cam morphology hips present. Cam morphology was present in 55.6% of dysplastic hips and 53.7% of non-dysplastic hips (p = 0.849). Cam morphology was most commonly located anterosuperior femoral head-neck in 70% of dysplastic hips and 65.9% in non-dysplastic hips (p = 0.747).

Conclusion

Cam morphology is frequently identified in pediatric patients with hip pain. The prevalence and location of cam morphology is not affected by the presence of co-existing hip dysplasia. During imaging work-up and treatment planning, it is important to recognize that a high proportion of pediatric hip dysplasia patients may have a co-existing cam morphology.

背景：髋关节发育不良和凸轮形态都是儿科患者髋关节疼痛的常见原因。然而，关于髋关节发育不良如何影响凸轮形态流行的文献有限。目的本研究旨在评估儿童髋关节发育不良患者与非发育不良患者相比是否具有相似的发生率和位置。材料和方法本回顾性研究评估了2012年4月至2024年6月期间患有髋部疼痛的儿科患者。数据收集基于两名肌肉骨骼放射科医生和一名儿科骨科医生对所有髋关节mri进行的图表回顾和影像学共识回顾。数据包括髋关节发育不良的存在，定义为外侧中心边缘角（LCEA） <18°，凸轮形态及其位置。使用卡方检验和Fisher精确检验，p值为显著性设置为0.05。结果在我们的研究队列中，107例患者（平均年龄15.3岁）118髋。年，66%女性，81髋行手术)，64髋存在CAM形态。55.6%的发育不良髋和53.7%的非发育不良髋存在凸轮形态（p = 0.849）。在70%的发育不良髋和65.9%的非发育不良髋中，凸轮形态最常位于股骨头颈前上（p = 0.747）。结论小儿髋部疼痛患者常出现凸轮形态。髋关节发育不良的存在不影响凸轮形态的流行程度和位置。在影像学检查和治疗计划中，重要的是要认识到，很大比例的儿童髋关节发育不良患者可能存在共存的凸轮形态。

Background: Accurate identification of parathyroid lesions is essential for diagnosis and management, yet conventional imaging techniques, including ultrasound and ^99mTc-sestamibi scintigraphy, can be discordant with the reference standard.

Purpose: To evaluate the diagnostic accuracy of elastography in differentiating parathyroid lesions from surrounding cervical tissues.

Methods: PubMed, Embase, and Scopus were searched through July 2025. Studies assessing elastography in patients with suspected or confirmed parathyroid lesions-including adenomas, hyperplasia, and carcinoma-and reporting diagnostic accuracy against histopathology or consistent follow-up were included. Pooled sensitivity, specificity, and summary receiver operating characteristic (SROC) curves were calculated using a bivariate random-effects model.

Results: Ten studies (739 patients) met inclusion criteria. Pooled sensitivity and specificity were 86.5% (95% CI, 79.8-91.3%) and 82.8% (95% CI, 76.0-87.9%), with an SROC area under the curve (AUC) of 0.91. Shear wave elastography outperformed strain elastography (AUC 0.94 vs 0.74, p = 0.009), and kPa-based stiffness measurements were superior to velocity measures (AUC 0.96 vs 0.83, p < 0.01). Accuracy was higher when parathyroid was compared with thyroid parenchyma/muscle (AUC 0.94) than with thyroid nodules (AUC 0.89), and in secondary versus primary hyperparathyroidism (AUC 0.96 vs 0.89, p = 0.004). High-frequency probes (≥10 MHz) further improved performance.

Conclusion: Elastography, particularly shear wave elastography with kPa-based measurements, demonstrates high diagnostic accuracy for differentiating parathyroid lesions from surrounding cervical tissues and may serve as a valuable adjunct to conventional imaging. Standardized protocols and larger multicenter studies are needed to confirm its clinical utility.

背景：准确识别甲状旁腺病变对诊断和治疗至关重要，但传统的成像技术，包括超声和^99mTc-sestamibi显像，可能与参考标准不一致。目的：评价弹性成像鉴别甲状旁腺病变与宫颈周围组织的诊断准确性。方法：检索至2025年7月的PubMed、Embase和Scopus数据库。研究评估了疑似或确诊甲状旁腺病变（包括腺瘤、增生和癌）患者的弹性成像，并报告了组织病理学或一致随访的诊断准确性。采用双变量随机效应模型计算合并敏感性、特异性和总受试者工作特征（SROC）曲线。结果：10项研究（739例）符合纳入标准。合并敏感性和特异性分别为86.5% （95% CI, 79.8 ~ 91.3%）和82.8% (95% CI, 76.0 ~ 87.9%)， SROC曲线下面积（AUC）为0.91。剪切波弹性成像优于应变弹性成像（AUC 0.94 vs 0.74, p = 0.009），基于kpa的刚度测量优于速度测量（AUC 0.96 vs 0.83, p）。结论：弹性成像，特别是基于kpa测量的剪切波弹性成像，在区分甲状旁腺病变和周围宫颈组织方面具有很高的诊断准确性，可以作为常规成像的有价值的辅助手段。需要标准化的方案和更大的多中心研究来证实其临床应用。
