Abstract

Background and Objectives : To evaluate the brain MR angiography(MRA) as a tool of diagnosis and follow up study in acute ischemic stroke. Methods : We reviewed 90 patients of acute ischemic stroke who received thrombolytic therapy and underwent brain MRI with MRA from September 1994 to July 1995. They were divided into two groups according to carotid system and vertebrobasilar system and then positive MRA findings were defined as stenosis or occlusion of vessels in relation with MRI lesions. Results : The positive MRA was shown more than 80% in large arteries and lower than 23% in small arteries. And also the MRA was shown the degree stenosis and underlying vessel abnormalities but could not precisely analyze the degree of improvement of vascular patency in this study. Conclusions : The MRA as a routine method addition to the MRI provides relatively reliable and noninvasive screening test and provides information that can be more complete evaluation and prognosis in patients of acute ischemic stroke.
