Synopsis

It is important for MMD patients to receive repeated life-time follow-up examinations for evaluation of bypass patency and collateral formation from neovascularization after bypass surgery. In this study we evaluated the clinical value of high-resolution (0.4 × 0.4 × 0.4 mm³ isotropic) CS TOF-MRA for assessment of STA-MCA bypass and neovascularization by using CTA as the reference. We found that high-resolution CS TOF-MRA could provide better visualization for both STA-MCA bypass and neovascularization than traditional CTA within a clinically reasonable time in MMD patients after surgical revascularization.
