[Abstract] Objective: To evaluate the wall features of symptomatic atherosclerotic middle cerebral artery stenosis by using HRMRI.Materials and Methods: One hundred and twenty-seven cases clinical data and image data about symptomatic atherosclerotic middle cerebral artery stenosis were analyzed. According to the DWI sequence, 127 cases were divided into symptomatic and asymptomatic group. Clinical data and wall features were compared between two groups (location, morphology, signal).Results: There was significantly difference between two groups in diabetes (χ2=23.446, P<0.001), male was more in symptomatic group than asymptomatic group (χ2=5.104, P=0.024), there was no significantly difference in two groups in age, hypertension, hyperlipidemia, smoke and drink (P>0.05). One hundred and ten plaques in 127 cases, ventral plaque was the most. Superior plaque was more in symptomatic group than asymptomatic group (χ2=4.257, P=0.039), irregular surface was significant difference in two groups (χ2=8.087, P=0.004), hyper-intensity was obvious difference in two groups (χ2=5.396, P=0.020).Conclusion: HRMRI could evaluate the wall features of atherosclerotic middle cerebral artery.
