After comparing with digital subtraction angiography (DSA) and high-resolution two-dimensional oblique-sagittal black-blood magnetic resonance imaging (2D-BB-MRI), we evaluated the value of high-resolution three-dimensional oblique-sagittal black-blood magnetic resonance imaging (3D-BB-MRI) in carotid artery stenting (CAS) for atherosclerotic carotid stenosis with cerebrovascular ischemic events. Two radiologists evaluated the maximum stenosis (Max-stenosis), maximum transverse plaque thickness (Max-TPT) and location of maximal lumen stenosis, plaque rupture, degree of maximal lumen stenosis and maximum longitudinal plaque extension (Max-LPE) on MRI images by consensus, and then compared the results with DSA. Our findings showed that the 3D-BB-MRI can provide a good preoperative preparation for CAS.
