Integrated model combining emphysema, Pi10, airway branch count, and clinical data detected undiagnosed COPD with AUC 0.83 (95% CI 0.80-0.86) in 5,014 lung screening participants, up from 0.69 for emphysema alone, reducing confirmatory spirometry referrals from 41% to 34%.
FAPI PET/CT showed 93.0% sensitivity vs 76.5% for FDG (p=0.002) in 176 patients with suspected HPB cancers. Nodal accuracy was 86.8% vs 71.1%. Dual-tracer approach did not improve accuracy. Prospective validation needed.
The b-value sets diffusion weighting in DWI MRI, changing sensitivity to water motion. Higher b-values increase diffusion sensitivity but lower SNR. Essential for DWI interpretation and radiology physics exams — part of a 100-question high-yield series.

ECFS-CTN consensus (Delphi process) supports chest CT for CF patients with hemoptysis, allergic bronchopulmonary aspergillosis, or NTM-positive cultures (>2 sputum samples or 1 bronchoscopic result). Final CT justification rests with treating clinicians.
One question — 'My illness has been a financial hardship to me and my family' — identifies financial toxicity in outpatient imaging patients with AUC 0.89–0.90, matching the full 11-item COST score (Spearman r=0.75). Valid even among patients who canceled appointments (AUC 0.88–…
Low-dose chest CT for lung cancer screening produced minimal testing burden overall (mean Testing Morbidities Index 97.5/100 at university vs 96.1/100 at safety-net site; p=.01), but safety-net participants reported significantly more pain/discomfort before and during the scan —…
Decision-analytic model: FDG PET/MR + low-dose chest CT achieved 97% staging accuracy (95% UI 94%–99%) vs 70% (64%–76%) for conventional imaging in stage III breast cancer, at an incremental cost of ~$3,000 per additional patient correctly staged (UI $1,500–$6,500).
A sciatic nerve variant shows an accessory muscle slip from obturator internus to piriformis splitting L5/S1 and S2 nerve roots — not a classic Beaton and Anson type. Always compare with the normal contralateral side to avoid misdiagnosis.
Radiologists Dr. Imran Lasker and Dr. Christoph Agten share their entrepreneurial journeys, discussing mindset shifts, challenges, and opportunities beyond traditional clinical roles.
Susanna Lee, MD, PhD, editor of Radiology Advances, discusses why open access matters for radiology: peer-reviewed imaging research should reach the full global medical community, not just those behind institutional paywalls — and how funding models must evolve to get there.
Hospital executives are actively pushing for AI reading without radiologists, and the slowest readers will be cut first, warns a new educational video. Survival options: boost reading speed, shift to procedural work, or acquire practice equity now.

Radiology pearl: Sagittal-only anterior cruciate ligament (ACL) assessment can lead to missed partial tears. Always evaluate the coronal and axial planes to confirm integrity.
The American Board of Radiology is bringing back the oral exam. ABR Executive Director Brent Wagner, MD, MBA, breaks down the changes in this RSNA interview — essential viewing for residents and program directors preparing for board certification.
A new Radiopaedia 2025 lecture correlates uterine tube segmental anatomy (intramural to fimbriae) directly with hysterosalpingography and MRI appearances, emphasizing findings when pathology is present, relevant pelvic relationships, and clinically significant arterial supply.
EASL's 2025 clinical practice guidelines update recommendations for liver vascular diseases—portal vein thrombosis, Budd-Chiari syndrome, PSOD, SOS, and more—emphasizing multidisciplinary, individualized care based on evidence published since the 2016 version.
EASL 2025 evidence-based guidelines for extrahepatic cholangiocarcinoma (CCA) address early detection, accurate subtype classification (distal vs. perihilar), and integration of molecular profiling into diagnosis and treatment — reflecting real-world clinical management gaps.
RSNA's two-day Spotlight Course on pediatric imaging covers case-based interpretation, age-appropriate protocols, and dose optimization for infants through adolescents — practical content aimed at building diagnostic confidence in pediatric patients.
RSNA's Spotlight Course delivers core pediatric imaging essentials, designed for radiologists and trainees seeking foundational knowledge in pediatric imaging.
AI Tool Extracts Body Composition Data from Routine Chest X-Rays
The molybdenum-99/technetium-99m generator is a cornerstone of nuclear medicine, providing a continuous supply of Tc-99m for diagnostic imaging. This tutorial explains the Mo-99 decay chain, the column-based separation of Tc-99m, and why this system is central to daily clinical…
ABR Executive Director Brent Wagner, MD, MBA details the evolving certification pathway for radiology residents — including the return of the oral exam — in this RSNA Unscripted episode aimed at trainees and program directors.

Combining arterial spin labeling (ASL) perfusion with PI-RADS v2.1 scoring raised AUC from 0.916 (PI-RADS alone) to 0.965 for clinically significant prostate cancer detection in 133 biopsy-confirmed patients — but findings await external validation.
A Navigating Radiology YouTube short stages a best-of-three chest X-ray contest between the MedRAX-2 AI model and a PGY-5 radiology resident. The video is designed to teach chest X-ray interpretation; the challenge outcome was not revealed in the description.
Axial resolution in ultrasound is determined by spatial pulse length (SPL)—shorter SPL yields better separation of structures along the beam axis. SPL depends on wavelength and pulse duration; damping reduces ringing, shortening SPL. Essential for board exams and clinical optimi…
