Magnetic resonance imaging with dual velocity encoded projection reconstruction acquisition

Magnetic resonance imaging with dual velocity encoded projection reconstruction acquisition

A phase contrast image is produced using a 3D projection reconstruction pulse sequence. A high velocity-to-noise image is produced by using a LOW VENC motion encoding gradient. Phase wrap errors caused by high velocity flow is corrected using phase information in a HIGH VENC image produced from high...

Zusammenfassung:A phase contrast image is produced using a 3D projection reconstruction pulse sequence. A high velocity-to-noise image is produced by using a LOW VENC motion encoding gradient. Phase wrap errors caused by high velocity flow is corrected using phase information in a HIGH VENC image produced from highly undersampled data acquired during the same scan.
