Abstract
Objective:To evaluate the characteristics of plaques of middle cerebral artery (MCA) in acute ischemic stroke of basal ganglia using T1-weighted 3D Volumetric Isotropic TSE Acquisition (T1W 3D-VISTA) and its clinical relevance.Materials and Methods:Patients with acute ischemic stroke of middle cerebral artery territory,which were diagnosed by DWI,underwent both MRA and T1W 3D-VISTA examinations.Patients were divided into two groups according to the distribution of infarction,one contained basal ganglia (BG,basal ganglia/basal ganglia as well as the area outside of it) and the other did not contain basal ganglia (N-BG).Distribution of blood vessel walls and the contrast ratio (CR) of signal intensity of the plaques to that of the corpus callosum were compared between BG and N-BG and their clinical characteristics were evaluated.Results:Among 52 patients with cerebral infarction and ipsilateral plaques in M1 (BG 30 and N-BG 22),a total of 1560 image slices were studied.Overall,of the 251 slices with identified plaques,the plaques located at superior wall of BG (37.74％) accounted for a higher proportion as compared with N-BG (10.26％)(P=0.004),and the plaques located at inferior wall (26.42％) and ventral wall (13.21％) of BG accounted for a lower proportion as compared with the plaques located at inferior wall (48.72％) and ventral wall (33.33％) of N-BG (P=0.047 and 0.039,respectively).The average signal intensity (CRs) of plaques of BG was lower as compared with plaques of N-BG (mean,0.84 and 0.92,respectively,P=0.001).The clinical characteristics (including age,gender,hypertension,diabetes,dyslipidemia,smoking,drinking,BMI,NIHSS score within 24 hours after admission,family history of stroke) had no significant difference between BG and N-BG (P＞0.05).Conclusion:T1W-3D-VISTA can detect the distribution of arterial atherosclerotic plaques and the relative signal intensity.As compared with plaques of N-BG,the plaques of BG are relatively more stable and account for a higher proportion at superior wall and a lower proportion at inferior wall and ventral wall of MCA M1 segment.关键词
