Diffusion-weighted MRI as a screening tool of stroke in the ED

Am J Emerg Med. 2002 Jul;20(4):327-31. doi: 10.1053/ajem.2002.33776.


This report describes a novel imaging technology for the evaluation of stroke patients. Diffusion-weighted magnetic resonance imaging can visualize hyperacute ischemic stroke which cannot be seen on computed tomography; moreover, it only takes few minutes to scan. We believe that diffusion-weighted magnetic resonance imaging, rather than routine computed tomography, should be considered when the emergency physician evaluates a patient with acute ischemic stroke.
