Abstract

A magnetic resonance method and system are provided for providing improved 3D imaging of blood vessels and the like, which provides suppression of both blood and fat signals and is insensitive to subject motion, thereby facilitating improved visualization of vessel walls. The image data pulse sequence includes a plurality of pulse series, where each series includes a dark-blood sequence, a fat-suppression sequence, and a data readout sequence. Each data readout sequence samples a particular radial direction within each partition (Kz value) that passes through the Kz axis, and different radial orientations are sampled in subsequent series to provide a stack-of-stars sampling scheme.
