Whole-heart NCMRA Using Single-Breath-Hold TFE EPI at 3T:Comparison with 3D-mDixon TFE Coronary MRA on Healthy Volunteers

Non-contrast-enhanced whole-heart coronary MRA(NCMRA) is a noninvasive modality for the detection of coronary artery disease. 3D-mDixon with compressed SENSE has been used in clinical practices but was limited to its scanning time of approximately 5-15 minutes. The EPI technique could shorten the scan time in MRI acquisition. The study aimed to evaluate the image quality of single breath-hold TFE-EPI NCMRA and 3D-mDIXON NCMRA with compression SENSE in healthy volunteers. The results showed there was no significant difference in image contrast between the LM, RCA proximal, and LAD proximal. The single breath-hold TFE-EPI sequence might have its own unique advantages.
