Imaging of the basilar artery terminal branches in a 55Â year old man with acute medial bithalamic infarctions. 3D time-of-flight MRA MIP image through the distal basilar artery shows a focal high grade stenosis of the left posterior cerebral artery (PCA) P1 segment. 2D postcontrast BBMRI image (b) oriented through the short axis of the stenosed vessel (a, line) demonstrates circumferential eccentric wall thickening and enhancement (arrow) compatible with an atherosclerotic plaque
