Technical implementation of VW-MR imaging. Technical implementation of VW-MR imaging. Comparison of a coronal 2D T1-weighted FLAIR VW-MR imaging sequence (A) and a 3D proton-density–weighted variable flip angle refocusing pulse, fast spin-echo VW-MR imaging sequence (B) in a healthy subject. Insets show magnified images of the carotid terminations with arrows pointing to the arterial wall. Comparison of a standard contrast-enhanced T1-weighted spin-echo sequence (C) and an optimized contrast-enhanced T1-weighted VW-MR imaging sequence (D) shows how blood suppression is needed to reveal an enhancing atherosclerotic plaque (arrow) in the left MCA M1 segment.
