Abstract Objective: To evaluate the presence, shape and enhancement degree of symptomatic middle cerebral artery atherosclerotic plaques by 3.0T high-field and high-resolution magnetic resonance imaging technology, and to evaluate the relationship between the stability of plaque and cerebral infarction. Methods: The imaging and clinical data of 60 cases of atherosclerotic middle cerebral artery were analyzed retrospectively, HR-T1WI shows plaque morphology and enhancement degree between plaque and pituitary, and the comparison between plaque and pituitary divided into three groups: strong enhancement, mild enhancement and no enhancement. Result: Sixty cases of symptomatic patients were included in the statistics, and 45 cases had eccentric plaques. The enhancement degree of middle cerebral artery plaque in 19 cases of acute phase, 14 cases of subacute phase, 15 cases of chronic phase and 12 cases without cerebral lesion were analyzed. The Spearman correlation coefficients between enhancement degree of plaque and enhancement degree of pituitary and P values were statistically significant. Conclusion: Middle cerebral artery eccentric atherosclerotic plaques are more common, and there is a close relationship between the stability of plaque and the incidence of cerebral infarction, and the combination can be used to identify other vascular diseases.
