Abstract：Objective: To apply 3.0T high-resolution MRI (HRMRI) in the diagnosis of basilar atherosclerotic in paramedian pontine infarction (PPI). Methods: Consecutive 53 patients with PPI were performed MRA and HRMRI, compared the differences in assessing the basal artery stenosis between the two methods. The distribution, composition features and remodeling index of basilar artery atherosclerosis were observed using HRMRI, the correlation of basilar artery atherosclerosis and cerebral infarction were analyzed. Results: Nineteen cases of basal artery stenosis deteeted by MRA (35.84%) compared with 34 cases detected by HRMRI (64.15%), there were significant statistically differences (P<0.05). Forty-four cases of basilar artery atherosclerosis were detected by HRMRI (83.01%). The basilar artery atherosclerosis were mainly distributed in the front and left sites, the percentage of eccentric plaques was 90.91% and unstable plaque was 59.09%. Negative remodeling was found in 15 patients, intermediate remodeling in 12 patients, and positive remodeling in 17 patients. The basilar artery plaques at or near the origin of the penetrating artery in 13 cases. Conclusion: HRMRI is more sensitive to detect basilar artery stenosis compared with MRA. The basilar artery atherosclerosis mainly distributes in the front and left sites in PPI patients, and plaque instability is high incidence. Morphological analysis of basal artery plaque using HRMRI has high value in patiens of PPI.
