Continuously moving table whole-body MR imaging is improved using respiratory motion detection and gating. A dual-velocity scan is applied, using lower velocity in combination with gating only when data are acquired from the abdominal and chest regions, whereas higher velocity is used during most part of the scan. Improved image quality is obtained in head-to-toe volunteer scans.
