High-resolution vessel wall MRI (vwMRI) of the intracranial arteries is an emerging diagnostic imaging technique
🔹link.springer.com/article/10.100…
🔹j-stroke.org/journal/view.p…
Today it is a useful tool to evaluate ICAD, differential diagnosis, even follow up

#ICAD
✅ICAD is still associated with the highest rates of recurrent stroke of any stroke subtype
✅Future research should look for optimal biomarkers
✅Current management should probably be tailored to the underlying stroke mechanism (ie: embolic vs hemodynamic)
