Three dimensional (3D) whole-heart (WH) coronary MR angiography (CMRA) requires an extended imaging time, but it may be reduced by providing a subject with visual feedback (VFB). Thirteen healthy volunteers were scanned and quality of 3D WH-CMRA images was compared among three scan conditions: free breathing (FB) with and without VFB (FB + VFB and FB - VFB, respectively) and multiple breath-holds with VFB (MBH + VFB). All but two subjects were able to complete all scans. The average scan times were 10.0 +/- 2.2, 10.0 +/- 2.5, and 8.2 +/- 1.3 min for FB - VFB, FB + VFB, and MBH + VFB, respectively. In the MBH + VFB condition, scan time was significantly reduced by 18% compared with both FB scans. No significant difference in image quality was observed between the FB - VFB and MBH + VFB conditions, but scores were significantly deteriorated at some segments in the FB + VFB condition. The MBH + VFB scan can be performed with a shorter scan time without failure or impairment of image quality.
