In the present study, Gd-DTPA continuous intravenous injection 3D MR angiography using 3D IR preparation Fast SPGR by means of 180° pulse for pulse preparation, was investigated for optimal imaging parameters. 3D IR preparation Fast SPGR (TR 11 ms, TE 1.9 ms) which was used in the present study was rendered free of recovery time and inhibition by initiating a null point for fat impossible. The present Gd-DTPA continuous intravenous injection 3D MRA cannot maintain intravascular Gd-DTPA in high concentration because of a very short imaging time, but also improve Gd-DTPA-fat contrast by establishing optimal preparation times of 150-200 ms and FA 40°, and outline clinically superior angiograms with excellent contrast.
