RACER-GRASP: Respiratory-Weighted Aortic Contrast Enhancement-Guided and Coil-Unstreaking Golden-Angle Radial Sparse MRI

摘要

PurposeTo develop and evaluate a novel dynamic contrast-enhanced imaging technique called RACER-GRASP (Respiratory-weighted, Aortic Contrast Enhancement-guided and coil-unstReaking Golden-angle RAdial Sparse Parallel) MRI that extends GRASP to include automatic contrast bolus timing, respiratory motion compensation and coil-weighted unstreaking for improved imaging performance in liver MRI.
