Deep learning reconstruction enables rapid musculoskeletal MRI sequences to achieve diagnostic quality comparable to standard acquisitions, reducing scan times without sacrificing image quality (quantitative details not provided in source).
Histotripsy is a needle-free, non-thermal focused ultrasound technique for tumor ablation, but a review finds its clinical evidence is limited to early feasibility studies. Robust trials demonstrating oncologic efficacy (such as local tumor progression-free survival) versus esta…
New AJR article proposes an 'intestinal stroke' pathway to standardize and expedite the radiologist's role in diagnosing mesenteric ischemia, emphasizing early CT interpretation and structured reporting.
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…
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…
This AJR podcast episode distills strategies for early-career radiologists considering career pivots, offering mindset shifts and actionable frameworks. Based on expert perspective, not empirical data.
In a retrospective study of 740 CT/PET-CTs, three commercial AI lung nodule tools detected similar actionable nodules (p=0.73). However, small measurement variations led to significantly more BTS 1-year follow-ups for one tool (p<0.001 vs. another). Fleischner guidelines were mo…
A letter to the editor discusses the recent systematic review and meta-analysis of vacuum-assisted vs core needle breast biopsy, highlighting methodological concerns (specific findings not available in the snippet).
In low-dose abdominal CT (median 1.34 mSv), deep learning-based denoising significantly improved quantitative noise and overall image quality, with denoised filtered back projection (FBP) rated best subjectively, though sensitivity and specificity for acute appendicitis did not…
A systematic review of AI in dental radiology finds significant impact on cephalometric, panoramic, and CBCT imaging, with CNNs, U-Net, and transformers as dominant architectures. The study bridges theory to clinical use and includes bibliometric analysis, though pooled performa…
A 3D-printed surgical microscope provides fixed 6.5× magnification, enabling trainees to suture 2-mm vessels. Prototypes deployed in four countries. Low-cost, portable solution could expand global microsurgery education, but rigorous comparison against standard microscopes is st…
In a randomized trial of 54 undergraduates, lecture-before-practice teaching improved practical ultrasound skills (median OSCE score 0.95 vs 0.82, P=0.002) and overall performance (0.9 vs 0.82, P=0.009) vs practice-first sequencing. Theoretical knowledge did not differ.
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…
