BREATH-HOLD, CONTRAST-ENHANCED, 3-DIMENSIONAL MR-ANGIOGRAPHY

Breath-hold gadolinium-enhanced three-dimensional magnetic resonance ( MR) angiography was performed with a high-performance gradient MR imag ing system in 10 volunteers with no history of vascular abnormalities (breath-hold interval, 28 seconds; repetition time, 4.0 msec; echo tim e, 1.9 msec; 0.4 mmol gadoterate meglumin per kilogram of body weight) . High-resolution three-dimensional time-of-flight angiograms of the a orta, renal arteries, pulmonary arteries, pelvic arteries, and portal venous system were successfully acquired in all cases.
