Our object is the evaluation of spatial relationship of MCA plaque and perforator in different types of MCA infarction using VW-MRI. We included 34 patients with acute MCA infarction and divided into 3 groups according to infarction pattern. We evaluated location relationship between perforators and plaques. Wall area, stenosis degree and plaque enhancement were calculated. There was difference in relationship between plaque and perforator, location and characteristics of plaque in different types of MCA infarction. In patients with BOD, the plaque margin was closer to perforator orifice with less stenosis and enhancement than patients with artery to artery embolism.
