While AI is increasingly applied in medical imaging education to boost quality, curricula worldwide remain inconsistent and lack standardised teaching guidelines, causing knowledge gaps. Review recommends faculty development, AI literacy, and standardised frameworks.
In a single-center study, virtual simulation training improved fetal MRI scanning skills for all technicians (score 54.19 to 66.62, p<0.001). Residents and junior technicians saw largest gains; senior technicians did not significantly improve.
MIT engineers have developed a portable ultrasound system that they say enables individuals with no ultrasound experience to accurately perform breast exams, potentially expanding access. (No clinical validation reported.)
Air pollution's negative impact on bone density is stronger in socioeconomically disadvantaged populations, suggesting a synergistic effect that compounds osteoporosis risk, a new study finds.
FDA has cleared an ultrasound-guided ablation system for treating benign thyroid nodules in adults, offering a non-surgical alternative to traditional surgery or active surveillance.
Pennsylvania has passed a medical imaging licensure bill, requiring radiologic technologists and other imaging professionals to be licensed. The legislation aims to ensure minimum competency standards and improve patient safety. (Specific details not reported in the source.)
Vanderbilt surgeons are the first to use a new PET imaging technique intraoperatively to assess excised breast tissue margins in real-time, potentially eliminating the need for pathology and reducing re-excision rates.
Whole-body MRI screening services are expanding, but patients face trade-offs: potential early disease detection versus risks of false positives, incidentalomas, and unnecessary procedures.
Focus on meaningful innovation that aligns with practice values when considering AI adoption, advises Tessa Cook, MD, PhD, on RSNA Unscripted.
Big Fin SEO launched white-label Generative Engine Optimization (GEO) services, enabling marketing agencies to offer AI-driven search optimization nationwide under their own brand.
Big Fin SEO announced white-label generative engine optimization services for marketing agencies. The launch targets nationwide agencies and is unrelated to radiology or medical imaging.
New MRI research sheds light on staging accuracy for endometrial cancer using the revised 2023 FIGO classification, potentially refining treatment decisions. (Exact findings not reported in source.)
A 100% interventional radiology position with flexible scheduling and a commencement bonus is advertised in Tucson, Arizona, via the ACR Career Center.
This educational lecture breaks down the greater and lesser sacs and key peritoneal recesses, providing a practical framework for radiologists to predict how fluid and disease spread within the peritoneal cavity on CT.
Geisinger Health System’s radiology employer profile is now live on the ACR Career Center, showcasing practice opportunities, benefits, and work culture for radiologists.
Independent private practice sets radiology's market benchmark, providing an anchor against employer exploitation, argues a new opinion piece.
Exam Requirements: Obstetrical Ultrasound (Revised 7-1-2026)
The American College of Radiology has updated its practice parameters and technical standards for general ultrasound examinations, with a revision effective July 1, 2026.
A study in JAMA Internal Medicine suggests that using total years smoked, rather than the current pack-year threshold, could simplify lung cancer screening eligibility and capture more patients likely to benefit from CT screening.
Nearly 100% of surveyed patients say they'd want to be informed when AI is used in their imaging, according to a study in Radiology. (exact figure not reported in source).
Interactive CT quiz from CTisus for July 2026, featuring diverse cases with detailed answers and Dr. Elliot Fishman's expert explanations.
Low muscle density on coronary CT angiography is associated with increased risk of major adverse cardiovascular events, a new study indicates. Exact risk metrics not reported in the available summary.
Meta-analyses of AI in radiology are often biased and methodologically flawed; authors call for more rigorous standards to improve reliability of pooled estimates.
An AI system used for triage in breast cancer screening reduced the number of mammograms requiring human reading by 50% while maintaining a population-level sensitivity of 94.3% compared with double reading (94.8%). Retrospective simulation using a large U.K. cohort.
Research in Radiology: Artificial Intelligence investigates personalized treatment strategies for intracranial aneurysms. Specific outcome measures were not provided in the source, warranting further review of the full study.
A single MRI sequence (T2-FLAIR) may be enough for AI brain tumor segmentation, but models trained this way show a 10–20% drop in Dice score when applied to external data, highlighting a generalizability gap.
In longitudinal radiomic analyses, patient visit frequency can introduce confounding, potentially biasing model outcomes. (Details not provided in source.)
A new registration method for breast MRI preserves tumor signal during alignment, enabling detection of true pathological complete response after neoadjuvant chemotherapy (exact figures not reported in source).
Radiology AI models require continuous, real-world postdeployment monitoring beyond test sets to detect silent failures and maintain safety, as performance can drift with changing data. A commentary highlights the lack of standardized frameworks for this critical phase.
