119 Intracranial Atherosclerosis Assessed with 7T MRI 5 Figure 3. Images in a 69-year-old man with a left-sided ischemic stroke obtained 56 days after symptom onset. Cardiovascular risk factors present were hypertension and diabetes mellitus. The Second Manifestations of ARTerial disease (SMART) vascular risk score was 37%, indicating a 37% chance of a recurrent vascular event within 10 years. A total of 14 vessel wall lesions were detected on the pre- and postcontrast 7T transverse 3D T 1 -weighted magnetization-prepared inversion-recovery TSE images (TR 3952 ms, TE 37 ms, TI 1375 ms, voxel size 0.8 x 0.8 x 0.8 mm 3 ). ( A ) In the anterior circulation, transverse postcontrast MRI show vessel wall thickening (white arrow) of the supra-clinoid portion of the right internal carotid artery and ( B ) the right M1-segment (white arrow). ( B and C ) In the posterior circulation, transverse postcontrast MRI show vessel wall lesions in the right P2-segment (white arrowhead in B ), and the basilar artery (arrow in C ).
