[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.
