Comparison of 12-mm thick maximum intensity projections from navigator-gated 3D bSSFP (left) and navigator-gated single-shot radial QISS (right) in a healthy subject. Scans were acquired with identical spatial resolution, navigator positioning, and navigator acceptance window. Compared with 3D bSSFP, single-shot radial QISS shows better suppression of signal from pericardial fluid and less sensitivity to flow and respiratory motion artifacts, resulting in more uniform vessel signal and improved vessel sharpness
