Silent magnetic resonance angiography (Silent-MRA), which combines the Silent Scan algorithm to achieve a zero echo time with an arterial spin-labelling method, has recently been introduced as a novel MRA technique. Many studies of Silent-MRA focused on evaluating vascular structure; however, reports of further investigations into the flow information generated by Silent-MRA cannot be found. To this end, we compared the flow-encoding Silent-MRA signal with phase contrast flow imaging and found a linear correlation between the two. This preliminary study demonstrates the potential power of using flow-encoding Silent-MRA in assessing complicated vascular disease.
