Evidence that stroke outcomes do not only depend on the infarcted brain, but also what’s left. The whole brain matters! #ResilienceIsKey
🎊 Our new study is now online in AJNR! While stroke research has focused on the infarct, we show using AI that non-infarct regions tied to brain plasticity and health also predict functional outcomes. @GregZ_MD @stanfordneuroi1 @StanfordRad @TheAJNR

Commercially available AI-accelerated MRI algorithms shorten acquisition time and improve image quality, with the potential downstream effects of increased number of images and higher demand on radiologists. @GregZ_MD

Important study! Stop doing CTAs!
Patients with isolated traumatic SAH and normal coagulation rarely need intervention. Our new study outlines a risk-based approach to guide follow-up imaging. Always grateful for @dyousem1’s inspiring mentorship.✨ @TheAJNR @hopkinsneurorad @Hopkins_Rad
