Abstract
Technical reliability was determined for triggering three-dimensional (3D) contrast material-enhanced magnetic resonance (MR) angiography with MR fluo roscopy. Technical requirements for high reliability were also identified. Reliability was evaluated in 330 consecutive patient studies of the neck, t horax, abdomen, and pelvis. Contrast material arrival was detected fluorosc opically in 325 of the 330 studies (98.5%), and the 3D sequence was success fully triggered in 321 of 330 studies (97.3%). Fluoroscopic triggering of c entrically encoded 3D MR angiographic acquisitions is a highly reliable mea ns of obtaining 3D MR angiograms with high spatial resolution.
