ASFNR clinical state-of-practice: For posterior circulation large vessel occlusion stroke, use noncontrast CT to exclude hemorrhage, CT angiography to identify occlusion, and MRI with DWI as reference standard. Imaging scores like PC-ASPECTS help select patients for thrombectomy.
The ACR Appropriateness Criteria 2026 update provides imaging guidelines for suspected or confirmed diffuse lung disease, covering initial evaluation, acute exacerbation, and surveillance.
New expert consensus framework for symptomatic B3 breast lesions: assess concordance, lower excision threshold for discordant/palpable lesions, conservative management for concordant non-atypical lesions, and risk-based surveillance for atypia.
ACR Appropriateness Criteria for indolent lung cancer: For patients with slow-growing subsolid nodules or atypical cysts where surveillance is chosen over intervention, imaging follow-up aims to detect changes that alter management, with modality selection guided by accuracy and…
AI-assisted appendicular fracture detection (AUC 0.847, 95% CI 0.811–0.881) improved accuracy for 2 of 3 radiologists (~76% → 83%, p≤0.001) and cut median read time 33% (12.9→8.6 s) in a retrospective MRMC study; prospective multicenter validation still needed.
AI assistance significantly improved radiologic technologist detection of intraventricular and subdural hemorrhage (5/30 reader-task comparisons, p≤0.007) but did not improve overall any-hemorrhage AUC in this retrospective 100-CT study.
AI (mostly U-Net CNNs) segments craniofacial airways on CBCT with Dice scores 0.90–0.97 and ICC >0.90 vs. manual methods across 14 studies. But external validation is scarce and only 1 study tested OSA prediction against polysomnography — not yet ready for routine use.
MRI radiomics predicts pathological complete response (pCR) in rectal cancer after neoadjuvant chemoradiotherapy: pooled sensitivity 0.82, specificity 0.86, AUC 0.85 (38-study meta-analysis). Deep learning models outperformed. Prospective validation still lacking.
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…
An LLM (GPT-5) extracted pNI-RADS and nNI-RADS scores from OPC surveillance reports with 93.3% and 90.3% agreement for NI-RADS 1 (no disease). For NI-RADS ≥2, exact category agreement was 73.1% (pNI-RADS) and 64.3% (nNI-RADS). Disease-status specificity was 0.95–0.99. Retrospect…
