Contrast-enhanced MR angiography (CE-MRA) permits accurate assessment of the abdominal aorta and the splanchnic arteries, including the celiac trunk and its branches. However, it is often restricted for patients undergoing dynamic-contrast-enhanced imaging of the liver in the same exam. In this study, we employ the recently introduced Relaxation-Enhanced Angiography without Contrast and Triggering (REACT) method using magnetization-prepared dual-echo Dixon for 3D free-breathing non-contrast-enhanced imaging of the celiac trunk. Initial results in healthy volunteer and patients are reported in comparison to the other techniques such as the conventional and arterial spin labeling (ASL) based balanced steady-state free precession (bSSFP) sequences.
