In a multicenter retrospective study, contrast-enhanced mammography showed high specificity for preoperatively ruling in pathologic nipple involvement in patients with breast cancer, allowing surgeons and patients to choose nipple-sparing surgery.

Purpose: To describe the development, implementation, and early outcomes of a structured social media communication strategy designed by the Breast Section of the Italian Society of Medical and Interventional Radiology (SIRM), aimed at engaging peers and trainees and fostering a professional online community in breast imaging. Methods: An observational descriptive study was conducted on the official Instagram, Facebook, and LinkedIn accounts Breast Imaging Section of SIRM, launched in April 2025. A task force of seven young radiologists managed the accounts without outsourcing, supervised by a senior board member of the section, ensuring scientific accuracy. Data from April 14 to August 20, 2025, were extracted from native platform analytics, including follower growth, reach, impressions, interactions, link clicks, and demographics. Instagram was considered the primary platform, with comparative analysis performed for LinkedIn and Facebook. Results: A total of 21 posts (including 6 reels) were published across platforms. Instagram showed the strongest performance, reaching 908 followers with an initial launch spike followed by steady linear growth. The median engagement rate was 2.29% per reach (0.90% per impressions). Profile visits occurred in 12.26% of reach, and follower acquisition averaged 4.26 per 1,000 impressions, confirming a functional conversion funnel from exposure to measurable action. Demographics revealed that most followers were aged 25–44 and primarily based in Italy, consistent with the professional target. LinkedIn (208 followers) showed higher interaction on institutional content, while Facebook (692 followers) reached older demographics, extending audience diversity. Conclusions: A structured, peer-led social media strategy can rapidly build a professional community in breast imaging. The initiative demonstrated that high-quality scientific content in accessible formats generates measurable engagement and may serve as a replicable framework for other radiological subspecialties.

Objectives: Accurate preoperative assessment of nipple-areolar complex (NAC) involvement is critical for surgical planning in breast cancer patients. While magnetic resonance imaging (MRI) is the established modality for NAC evaluation, contrast-enhanced mammography (CEM) has emerged as a potential alternative. This study aims to compare the diagnostic performance of CEM and MRI in predicting NAC involvement in a real-world setting, using histopathology as the reference standard. Materials and methods: A retrospective cohort of 195 women with biopsy-proven breast cancer (91 CEM, median age 66 years; 104 MRI, 53 years) underwent preoperative imaging at a single institution. Imaging criteria for NAC involvement were defined. Two radiologists independently evaluated the images, with discordances resolved by consensus. Diagnostic performance was compared between CEM and MRI using Fisher’s exact test. Multivariable logistic regression identified predictors of NAC involvement. Results: NAC involvement was histologically confirmed in 11.0% (10/91) CEM and 19.2% (20/104) MRI cases ( p = 0.110). Sensitivity was similar, 60% for CEM and 50% for MRI ( p = 0.897), with nearly identical specificity (96.3% vs. 96.4%; p = 0.709). In situ components were frequently observed in NAC-positive cases (CEM: 90%; MRI: 75%) but were not statistically predictive. Independent predictors included peri-areolar thickening for CEM (OR 26.3; 95% CI 3.9–100; p = 0.0007) and abnormal NAC enhancement (OR 14; 95% CI 1.5–133.5; p < 0.001) and shorter tumor-to-nipple distance (OR 0.28, 95% CI 0.1–0.6; p < 0.001) for MRI. Conclusions: Notwithstanding a difference in patient age between the CEM and MRI cohorts, which mirrors the different clinical application of the two imaging modalities, CEM demonstrated diagnostic performance comparable to MRI for NAC assessment, offering high specificity and clinical utility in patients unsuitable for MRI. Key imaging features (e.g., peri-areolar thickening, NAC enhancement) aid preoperative decision-making. These findings support CEM as a viable alternative for NAC evaluation, particularly in cases of contraindications to MRI. Key Points: Question Preoperative assessment of nipple-areola complex (NAC) involvement in breast cancer impacts surgical decisions. It is unclear whether contrast-enhanced mammography (CEM) may provide diagnostic performance comparable to magnetic resonance imaging (MRI) in assessing NAC involvement. Findings CEM and MRI show comparable diagnostic performance for NAC involvement, with similar sensitivity, specificity, and predictive values. Clinical relevance CEM offers a reliable, accessible alternative to MRI for evaluating NAC involvement, supporting surgical planning in breast cancer patients, especially when MRI is contraindicated or unavailable.

Scholarly activity and teaching are recognized components of radiology training, but their distribution across residency years is poorly characterized in Italy. We conducted an anonymous cross-sectional online survey of Italian radiology residents between August and September 2024. Among 176 consenting respondents, we assessed scientific article authorship, congress presentation experience, and formal teaching experience. Associations with postgraduate year (PGY) were examined using multivariable logistic regression adjusted for sex and geographic macroarea, with Holm correction across the three main outcomes. Overall, 40.3% reported scientific article authorship, 34.7% congress presentation experience, and 31.8% formal teaching experience; 10.2% had been first author on a scientific article. Article authorship was reported by 16.7% of PGY1 and 64.5% of PGY4 residents, with higher adjusted odds in PGY3 (aOR 6.49, 95% CI 2.54–16.55) and PGY4 (aOR 9.58, 95% CI 3.34–27.48). Congress presentation experience was reported by 56.6% of PGY3 residents, while formal teaching was most frequent in PGY4 (58.1%; aOR 5.61, 95% CI 2.07–15.24 vs. PGY1). Perceived value of research did not differ across PGYs. Scholarly and formal teaching engagement was more frequently reported among later-year residents; longitudinal studies are needed to characterize within-resident development.
