[Current techniques in MR imaging of cerebral infarction].
The imaging of cerebral infarction is a current topic now that the usefulness of both thrombolysis for hyperacute infarction and carotid endarterectomy has been established. Diffusion-weighted imaging (DWI) by EPI is a highly sensitive method of detecting hyperacute infarction. Further, the combination of DWI and perfusion MR makes it possible to detect hyperacute infarction as well as predict the final size of infarction. Contrast-enhanced MRA can demonstrate carotid bifurcation without flow-related signal loss within 30 seconds and can visualize major cervical arteries from the aortic arch to the circle of Willis.
