Can 3D Pseudo‐Continuous Territorial Arterial Spin Labeling Effectively Diagnose Patients With Recanalization of Unilateral Middle Cerebral Artery Stenosis?

A typical patient with R-MCA undergoing stenting before (top row) and after (bottom surgery. 65-year-old male severe stenosis. (a) DSA showed that stenting, the stenosis was significantly alleviated, blood flow recanalized, distal branches were well visualized. (b) DWI no obvious high signal operation. (c) Preoperative 3D pcASL low perfusion area visible in M6, postoperative had returned to normal. (d) (e) tASL M3, M5, M6 areas lower than of contralateral side, hypoperfusion normal by Wang et al (175–183).
