The artery is open. Is the brain actually getting blood? 🧠🤔

My latest #RIAM explores no-reflow on perfusion imaging after thrombectomy and why reopening the artery is only part of the story.

CT in obese patients is a trade-off: ⬆️ X-ray attenuation usually means cranking up the dose just to keep images diagnostic.

New in @radiology_rsna: can photon-counting CT break that trade-off? Same patients, both scanners

🫁🦴 One scan, two screenings?
Lung screening CT also images the spine. Can automated CT-based BMD predict vertebral fractures, and is it linked to mortality?

A low NIHSS doesn’t make a basilar occlusion low stakes. But who really benefits from EVT? 🤔
This @radiology_rsna study suggest the answer may depend on just how mild “mild” is.👀
