Non-Contrast-Enhanced Abdominal MRA Using Velocity-Selective Saturation and Multiple Inversion Recovery

Hattie Z. Dong¹, Taehoon Shin¹, Dwight G. Nishimura¹

A new non-contrast-enhanced method based on velocity-selective saturation and multiple inversion recovery (VS-MIR) was developed for magnetic resonance angiography (MRA) in scan times as short as a single breath-hold. VS-MIR leads to excellent background suppression while relaxing the in-flow requirements for vessel contrast. MRA results with this method in the abdominopelvic region demonstrated good vessel contrast over a wide superior-inferior range.
