A single case report: high-grade prostate adenocarcinoma (Gleason 5+5=10) debuted with cervical lymph node skip metastases and extensive central venous thrombosis — no pelvic or bone involvement — despite only a PI-RADS 3 mpMRI lesion. Unexplained thrombosis in elderly men shoul…
CTA is the go-to first-line test for reversible cerebral vasoconstriction syndrome (RCVS) at 77% of French academic centers, but confirmatory and follow-up strategies vary widely. 85% document reversibility with long-term imaging; authors propose a pragmatic pathway pending pros…
In 10 patients with local CSF-venous fistula (CVF) recurrence after transvenous embolization (TVE), two failure mechanisms emerged: Onyx cast margin leakage (external/basivertebral veins) and incomplete internal epidural venous plexus occlusion — findings that may guide technica…
In 2,652 CT exams (4.1% fracture prevalence), Aidoc AI detected acute cervical spine fractures with sensitivity 89.1% vs 94.5% for radiologists; combined sensitivity/specificity favored radiologists (p=0.02). Single-center retrospective study.

On ankle MRI, chronic periosteal sleeve avulsion of the flexor retinaculum is easily missed on coronal views alone. The axial sequence clearly demonstrates the retinaculum wrapping around the medial malleolus tip instead of inserting sharply, with associated chronic scar plate a…
This item is a literary/cultural essay about deception in society, routed from a general blog. It contains no radiology, imaging, or clinical content and does not meet RadPigeon editorial scope.
The American College of Radiology advises radiology practices to immediately review CMS Q3 National Correct Coding Initiative (NCCI) edits, as quarterly updates directly affect billing compliance and claim denials for diagnostic imaging.
ACR urges Congress to fund NIH All of Us program, collecting diverse health data including imaging for precision medicine.
FDA officials outlined programs to streamline regulatory review for radiology AI tools at the ACR DSI Summit, aiming to accelerate safe innovation (specific initiatives not detailed in source).
The federal administrative fee for initiating No Surprises Act independent dispute resolution cases has been lowered, reducing costs for radiologists challenging out-of-network payer reimbursements (exact new fee not reported in source).
Subtle Medical's deep-learning CT enhancement software received FDA clearance. The algorithm denoises and sharpens CT images, potentially allowing lower-dose acquisitions without sacrificing diagnostic quality. (Exact performance figures not reported in source.)
DeepHealth debuts AI-Enhanced Reporting Pro, a tool designed to integrate artificial intelligence into radiology reporting to streamline workflow (specific capabilities and performance metrics not detailed in source).
