Role of Intracranial Vessel Wall (VW) MRI in Evaluating Luminal Pathologies.

Intracranial vessel wall (VW) MRI is a state-of-art technology to evaluate vessel wall diseases. It requires high spatial and contrast-to-noise ratio (CNR) resolution as well as capability of blood and cerebrospinal fluid (CSF) suppression to visualize the arterial wall. Our vessel wall protocol including T2 -weighted, 3D time of flight (ToF) MR angiography, diffusion-weighted imaging (DWI), gradient echo imaging (GRE), high resolution post contrast 3D T1-weighted turbo spin echo (TSE) with motion-sensitized driven-equilibrium (MSDE) black blood sequence and post contrast 3D T1-weighted volumetric isotropic fast field echo (FFE) done within 30 minutes which is capable to show vessel wall diseases.
