171 MRI Vessel Wall Imaging after Intra-Arterial Treatment for Acute Ischemic Stroke 7 Figure 5 . A 75-year-old female with an anterior circulation ischemic infarction of the left MCA territory (non-IAT group, number 30 in Supplemental table 1 ). Transverse and coronal precontrast ( A and C ) and postcontrast ( B and D ) magnetization-prepared inversion recovery turbo spin-echo (MPIR-TSE) vessel wall images at 7T were performed 10 days after symptom onset of the ischemic infarction. Eccentric vessel wall enhancement is seen of the supra-clinoid portion of both intracranial carotid arteries ( B and D ; arrows). The basilar artery appears normal (white arrowheads in A and B ).
