Extramammary metastases to the breast are extremely rare and vary widely in their clinical and imaging features. Diagnosis may be challenging as lesions can mimic both primary breast cancer as well as benign breast lesions. The goal of this review is to describe the radiologic and pathologic features of the most common primary tumors that metastasize to the breast including lymphoma, melanoma, lung carcinoma, gynecologic carcinoma and sarcomas.

Purpose
Vertigo is associated with superior semicircular canal (SSC) abnormalities such as thinning (SST) and dehiscence (SSD). Recent work demonstrates that SST/SSD be reliably assessed using high-resolution non-contrast enhanced CT head (HR-NECTH). This study investigates and compares the prevalence of SST/SSD in emergency department (ED) patients without vertigo, with vertigo with identifiable causes of their symptoms (explained vertigo), and without (unexplained vertigo).
Methods
This retrospective study examined ED patients with and without vertigo who received HR-NECTH. Patients were enrolled and separated into three groups (patients without vertigo, explained vertigo, and unexplained vertigo) and their temporal bones (TB) were examined using HR-NECTH. Prevalence of SST/SSD on individual TB in patients without vertigo and of SSC abnormalities among the three cohorts were tabulated and analyzed with confidence intervals and Fisher's exact test.
Results
Prevalence of SST/SSD was 2 % (95 %CI [0.63 %–5.4 %) and 1 % (95 %CI [0 %–2.4 %]), respectively, among 200 individual TB from ED patients without vertigo. There was statistically significant higher prevalence of SSC abnormalities in ED patients with explained vertigo (16 %, 95 %CI [8.8 %–23.2 %], P = 0.02) and unexplained vertigo (25 %, 95 %CI [16.5 %–33.5 %], P = 0.0001), compared to those without vertigo (5 %, 95 %CI [1.3 %–10.7 %]).
Conclusion
SST/SSD prevalence rate among ED patients without vertigo is similar to cadaveric gold-standard on HR-NECTH while those with vertigo had higher prevalence rates of SSC abnormalities. HR-NECTH can be used to assess for SSC abnormalities in ED vertigo patients to expedite diagnosis and forego additional TB imaging.
目的：眩晕与上半规管（SSC）异常有关，如变薄（SST）和开裂（SSD）。最近的研究表明，使用高分辨率非对比度增强CT头（HR-NECTH）可以可靠地评估SST/SSD。本研究调查并比较了急诊科（ED）无眩晕患者、有明确病因的眩晕患者（解释性眩晕）和无眩晕患者（解释性眩晕）中SST/SSD的患病率。方法：本回顾性研究检查了接受HR-NECTH治疗的伴有和不伴有眩晕的ED患者。纳入患者并将其分为三组（无眩晕、解释性眩晕和解释性眩晕），并使用HR-NECTH检查其颞骨（TB）。将三个队列中无眩晕的结核病患者的SST/SSD患病率和SSC异常的患病率表列出来，并使用置信区间和Fisher精确检验进行分析。结果：在200例无眩晕的ED患者中，SST/SSD的患病率分别为2% （95% CI[0.63% - 5.4%]）和1% （95% CI[0% - 2.4%]）。有解释性眩晕的ED患者SSC异常发生率（16%,95% CI [8.8% - 23.2%], P = 0.02）和有解释性眩晕的ED患者SSC异常发生率（25%,95% CI [16.5% - 33.5%], P = 0.0001）高于无解释性眩晕的ED患者（5%,95% CI[1.3% - 10.7%]）。结论：无眩晕ED患者的SST/SSD患病率与尸体的HR-NECTH金标准相似，而有眩晕ED患者的SSC异常患病率较高。HR-NECTH可用于评估ED眩晕患者的SSC异常，以加快诊断并放弃额外的结核病成像。

Radiology is integral to global health, yet low-resource settings face major workforce disparities. Global health radiology (GHR) seeks to improve imaging access, quality, and training in underserved regions, and faces increasing interest among Canadian trainees. However, limited data exist on Canadian radiology program directors' (PDs) perspectives, which are central to shaping educational policy. This study explored PDs' views on GHR relevance, resident and faculty engagement, barriers to integration, and future directions. A bilingual online survey was distributed to PDs of all 16 accredited Canadian radiology residency programs. The survey assessed attitudes toward GHR, teaching practices, faculty involvement, barriers, and resident interest. Descriptive statistics were used for quantitative analysis, complemented by qualitative responses. Fourteen PDs responded (87.5 %). Most (72 %) rated radiology's contribution to global health as essential or very important, and 79 % considered GHR a valid academic career path. While 86 % deemed formal GHR training at least moderately important, only 29 % of programs included it in curricula, and 21 % offered GHR electives. Faculty involvement was limited, with 50 % reporting some engagement, typically less than one half-day per week. Resident interest is rising, with 57 % of PDs noting increased demand over the past five years. Barriers included lack of faculty expertise (71 %), curriculum time constraints (64 %), and absence of national guidelines (57 %). Canadian PDs recognize the importance of GHR but implementation remains limited. Expanding faculty capacity, embedding GHR themes into existing curricula, and developing national frameworks may help bridge the gap between interest and practice, advancing socially responsible radiology training in Canada.

Purpose
Artificial intelligence (AI) has the potential to improve diagnostic accuracy and efficiency in breast imaging. Though radiologists appreciate its benefits and limitations, patients' receptiveness and understanding of AI in breast imaging remain unclear. We aim to investigate patients' preferences and perceptions of AI and its role in breast imaging interpretation.
Methods
Structured questionnaires were distributed to patients presenting for imaging or biopsies within the breast radiology department at six facilities within an urban hospital system between September 2023 and March 2024. The survey included 21 questions evaluating patient demographics and attitudes towards AI in breast imaging analysis. Data was analyzed using Pearson's Chi squared test and p < 0.05.
Results
Among 130 survey respondents, 48 % supported the use of AI in breast radiology, independent of age, sex, race, education, and subjective understanding of AI. A significant percentage (70 %) of patients that have heard of examples of AI used in the medical field support its implementation in breast imaging (p < 0.0001). Most patients (64 %) would feel more comfortable with AI implementation, if they better understood how AI was used. The most frequently cited concern about AI in breast radiology was loss of patient-doctor relationship (43 %). Only 16 % would accept AI integration if it increased imaging cost. Most patients (60 %) prefer a primary radiologist read with a second physician consulted for questions versus AI.
Conclusions
Patients have variable understanding and preferences about AI in breast imaging. Educational measures to increase transparency and understanding of medical AI may improve patient trust in their healthcare experience.

Purpose
The goal of this study was to evaluate outcomes of new suspicious enhancement in women undergoing breast MRI during neoadjuvant chemotherapy (NAC).
Methods
This retrospective review evaluated patients with breast cancer who underwent NAC with breast MRI performed from 2012 to 2022. Patients were included for further evaluation if an MRI during NAC recommended additional workup or biopsy of any new suspicious enhancing lesion separate from the index tumor. Medical records, subsequent imaging studies, and pathology reports were reviewed in eligible patients to identify lesion characteristics and outcomes of further workup.
Results
A total of 425 patients had pre- and post-treatment MRI. After exclusions, final study population included 14/425 (3.3 %) patients with new suspicious findings after initiation of NAC, none (0/14, 0 %) of which were shown to represent malignancy on biopsy, surgery, or follow-up. Imaging manifestations included non-mass enhancement (5/14, 35.7 %), enhancing foci (5/14, 35.7 %), and masses (4/14, 28.6 %), with the new finding contralateral to the malignancy in 10/14 (71.4 %) and ipsilateral in 4/14 (28.6 %). Most patients (11/14; 78.6 %) demonstrated an imaging response to NAC. Of 11 patients with pathology, stromal fibrosis and fibrocystic change were described most commonly, in 8/11 (72.7 %) and 5/11 (45.5 %) respectively. Inflammatory cysts were present in 8/14 patients (57.1 %).
Conclusion
New enhancing lesions on breast MRI during NAC, particularly in setting of treatment response, are unlikely to indicate malignancy. This data corroborates other contemporaneous studies investigating this topic. Radiologists can incorporate this mounting evidence to help limit unnecessary workups.
