No FDA-approved PSMA-targeted PET radiopharmaceutical ([68Ga]Ga-PSMA-11, [18F]DCFPyl, [18F]rhPSMA-7.3) has proven diagnostic superiority for prostate cancer imaging; they differ in clearance routes (renal vs hepatic) and supply logistics, so choice should be guided by operationa…

Adding T1 subtraction maps increased consensus-based enhancing component volumes in all 20 treatment-naïve mild pediatric brain tumors (median +41.9%, p<0.001); 35% of cases had a substantial >100% volume increase. Small retrospective study without pathologic gold standard.
When suspected spinal CSF leak imaging is negative or discordant, neuroradiologists should consult directly with patients to reconcile findings, direct next steps, and reduce diagnostic delays—stepping out of the reading room for better care.
In Medicare strokes, AI adoption for LVOs tripled by 2022 but was driven by hospital type and geography, not patient demographics or severity. AI use was 21% in 2022, highest at comprehensive stroke centers (OR 1.5) and in the Stroke Belt (OR 2.0).
CSF-venous fistulas can occur without an associated meningeal diverticulum, arising directly from a normal nerve root sleeve or the thecal sac. In this retrospective multicenter case series, two rare variant types are identified and clinically characterized, expanding the imagin…
Standing weight-bearing CT myelography revealed disc space collapse, increased posterior disc bulge, and severe canal narrowing not apparent on supine imaging in 3 patients with intradiscal vacuum phenomenon (IVP), suggesting supine studies may miss dynamic stenosis.
Opportunistic screening of routine CT exams (e.g., abdominal scans) identifies previously unreported vertebral fractures, flagging patients for osteoporosis workup and potential treatment.
OU Health has named a new chair for its radiological sciences department, as reported by AuntMinnie. Details of the appointment were not immediately available.
Hologic recalled its Brevera 9G breast biopsy needles in January due to risk of metallic particle shedding in tissue and is now boosting production of an alternative biopsy needle to address the shortage.

DeepHealth has expanded its breast imaging AI platform with additional advanced features, though specific capabilities were not detailed in the announcement.
Tracking how a woman's AI risk score increases between two screening mammograms predicts future breast cancer better than the most recent score alone. Women with the fastest score rises had a significantly higher risk. If prospective data confirm this, the velocity metric could…
The European Society of Radiology's SOLACE Project has released public-facing videos promoting low-dose CT lung cancer screening, emphasizing that early-stage detection — before symptoms appear — improves treatment outcomes.
A Maine jury awarded $23M — reportedly the largest non-death malpractice verdict in state history — against Northern Light Health after a radiologist failed to identify a spinal cord injury on CT. Case underscores high-stakes liability in emergency spine imaging.
Arizona Gov. Katie Hobbs signed SB 1165 on June 19, requiring insurers to cover follow-up breast imaging. The law adds Arizona to a growing list of states mandating coverage for supplemental screening in women with dense breast tissue or abnormal findings.
Retired radiologist Janet H. Sung, MD, has donated $1 million to the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo, honoring her late husband.
A radiology group has launched a high school outreach program combining in-person observational rotations with virtual sessions to expose students to the full interventional radiology patient care cycle, from consultation to follow-up.
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.
In the LUMIR challenge, deep learning registration methods outperformed optimization-based approaches on 590 test brain MRIs, producing robust, diffeomorphic deformations that generalized to unseen diseases, protocols, and species in zero-shot tasks.

Non-DCE MRI O-RADS score has excellent inter-rater agreement (κ=0.90) and high PPV for adnexal masses; ADCmean of solid (≤1.3×10⁻³ mm²/s) and cystic (>2.07×10⁻³ mm²/s) components perfectly discriminate malignancy (AUC 1.00, 0.95) in a retrospective study.
In retrospective study of 167 HCC lesions on MRI, moderate-to-severe hepatic iron overload independently reduced LR-5 assignment (OR 0.08, 95% CI 0.02–0.28) and altered key LI-RADS features: washout and capsule.
