Relaxation-Enhanced Angiography without Contrast and Triggering (REACT) is a MR angiography technique without cardiac triggering, breath holding and contrast agent injection and is able to show robust blood-to-tissue contrast over multiple anatomies. This study aims to investigate the feasibility of REACT on central veins by comparing it with conventional CE-MRA and catheter angiography. Results showed that the image quality acquired from REACT was comparable to that from CE-MRA and there was no difference in central venous stenosis evaluated by REACT, CE-MRA and angiography.
