The American Academy of Neurology’s new guidelines on using MRI for stroke may represent best practice, but practical issues remain, interviews with several experts revealed.
In the July 13 issue of Neurology, the academy compared all the scientific data through 2008 on diffusion- weighted and perfusion-weighted imaging in acute ischemic stroke. A panel of experts in vascular neurology and radiology found DWI is established as useful and should be considered instead of noncontrast CT for the diagnosis of acute ischemic stroke within 12 hours of symptom onset.
