The ACR has issued its 2026 update to Appropriateness Criteria for myelopathy, providing evidence-based imaging guidance for acute, chronic, and vascular causes of spinal cord dysfunction to help differentiate extrinsic from intrinsic pathology.
In 82,957 women with negative screening mammograms (Kaiser Permanente cohort), combining Mirai AI, a 313-SNP polygenic score, and BCSCv3 clinical risk reached C-index 0.70 (95% CI 0.69–0.71) vs 0.66, 0.62, and 0.61 for each alone — supporting integrated risk-stratified screening.
After venous sinus stenting for pulsatile tinnitus, temporal bone remodeling occurred in 73.1% of patients with follow-up CT (38/52). Remodeling was significantly more likely with a diverticulum vs isolated wall dehiscence (85.7% vs 47.1%; adjusted OR 8.08, 95% CI 1.31-49.73), a…
Across >3 million multicenter emergency department encounters, overall ED neuroimaging utilization doubled from 2016 to 2025. Head CT without contrast remained dominant, but CT perfusion use rose >5-fold over the same period, signaling a marked shift in acute stroke workup inten…
In 221 patients undergoing cardiac CT/CTA, epicardial adipose tissue volume (EAV) independently associated with CAD after adjusting for traditional risk factors and calcium score; extensive plaque burden rose from 15.6% to 46.7% across EAV quartiles. EAV did not predict high-ris…
AI-assisted biparametric MRI (uAI, United Imaging) raised novice-reader AUC from 0.684 to 0.744 and sensitivity from 0.71 to 0.79 at PI-RADS ≥3 in 646 men; experienced-reader sensitivity gains were smaller and nonsignificant (p=0.344/0.291). Retrospective.
90% of students preferred a combined 3D-model plus 2D-image approach over either alone in station-based dermatology learning. 2D images scored marginally higher for diagnostic skill (7.3/10) and clinical application (7.2/10) vs. 3D models (6.8 and 6.7). Findings are perception-b…
Neurosurgical technique paper describes a standardised retractorless bifrontal craniotomy approach—pericranial flap harvest, frontal sinus obliteration, bilateral olfactory nerve dissection, intradural repair—for traumatic anterior fossa CSF fistulas. Outcomes quantified only qu…
Cross-sectional survey of 368 Jordanian medical students found AI-tool users had significantly more positive attitudes toward AI-integrated anatomy teaching (p<0.001); chatbots were the most-used AI tool (73.9%), but traditional slides remained the dominant study resource (91.9%…
3D T1 VIBE detects intracavernous cranial nerves far better than MPRAGE in neuro-ophthalmic MRI. In 54 exams, VIBE visualized CN V1 in 65–70% vs 6–9% and CN VI in 70–78% vs 19–22% for MPRAGE (all p<0.001), suggesting VIBE should be the preferred sequence.
Fish-mouthing (focal end convergence) occurred in 20% of Surpass Evolve flow diverter cases at 1 month but resolved in most, falling to 7% at 1 year. Fusiform shape, multiple aneurysms, and MCA location were risk factors. Retrospective; n=94.
A DL-generated high-contrast thin-slice CT (HCCT) from plain NCCT pushed inter-rater ASPECTS correlation from 0.72 to 0.94 (p<0.001) in 303 LVO stroke patients across 4 centers — outperforming standard NCCT for early ischemic change detection and favorable-outcome prediction.
Acute-phase T2-FLAIR radiomics improved risk stratification for delayed encephalopathy after CO poisoning: AUC 0.876, sensitivity 0.80, specificity 0.84 in held-out testing. Deep white matter was the dominant signal source. Retrospective; not externally validated.
Deep learning-accelerated DIR MRI reduced optic nerve scan time by 44% (23 min → 13 min) in 75 patients with suspected optic neuropathy, detected significantly longer lesions than STIR (β=7.4–7.6%, p<0.001), and was interchangeable with conventional DIR. Prospective single-cente…
Baseline PVR ≥300 mL triples risk of PAE failure: composite endpoint (prostate surgery or indwelling catheter) 38.7% vs 11.3% (RR 3.43; 95% CI 1.76–6.70; p=0.0003) in this retrospective cohort. Early symptom scores improved similarly regardless of PVR, but durability suffers.
Interventional radiology is consolidating into a distinct specialty: the share of radiologists doing any IR work fell from 66.9% to 49.6% (2008–2023), while those with >90% IR workloads doubled (4.1%→8.8%), and the odds of super-majority IR work rose 65% by 2020–2023 (OR 1.65; 9…
A 'Lessons in IR' M&M case highlights Sweet syndrome — an acute febrile neutrophilic dermatosis — mimicking central venous port infection, underscoring that not all port-site inflammation is infectious. Rare but important diagnostic pitfall for IR teams.
In 112 mammograms read by 10 residents, AI changed the BI-RADS category in 9.7% of assessments and altered diagnostic confidence in 19.2%, with upgrades outnumbering downgrades. Sensitivity for BI-RADS 4+ rose from 72.0% to 82.3% against an expert-consensus standard, though this…
A logistic regression model combining mammographic descriptors, age, and DCE-MRI enhancement classified BI-RADS 4/5 microcalcifications with 90.9% accuracy (F1 0.889) in preliminary internal testing of 53 biopsy-proven cases. Findings require multicenter validation before practi…
Incidental finding follow-up remains fragmented and error-prone in radiology. This RSNA session examines AI-enabled operational infrastructure—using breast imaging as a case example—to improve tracking, communication, and care continuity while reducing administrative burden.
A study suggests breast ultrasound AI may achieve sensitivity comparable to radiologists in pregnant and lactating women — a population with notoriously challenging imaging. Numbers and design details not reported in source; findings require independent validation.
