The purpose of our study was to summarize the typical imaging performance of PACNS and evaluate the value of 3D- VW-MRI sequence in demonstrating the detailed information in detection, diagnosis, evaluation, and follow-up for PACNS.
Figure 1：(A): MRA demonstrated smooth wall and no obvious stenosis. (B): Head MRI showed abnormal signals in the left oculomotor nucleus. (C-E): 3D VW-MRI showed unevenly thickening and abnormal enhancement of basilar artery，bilateral posterior cerebral artery and middle cerebral artery. (F-G):Curved plannar reconstruction by 3D-VW-MRI showed the left and right middle cerebral artery had no apparent enhancement after 4 months therapy, while the vessel wall was getting thickness.
Figure 2：(A):MRA revealed multiple stenosis of both the anterior circulation and the posterior circulation. (B~H)3D VW-MRI showed smooth, concentric arterial wall thickening and enhancement of bilateral vertebral artery, the left internal carotid artery and middle cerebral artery.
