Pre-Scan Breathing Pattern and Image Quality in Respiratory-Triggered T2-Weighted Liver MRI: Radial Versus Cartesian Fast Spin Echo.
BACKGROUND Respiratory-triggered T2-weighted imaging (T2WI) may use rectilinear sampling (respiratory-triggered fast recovery fast spin echo [RT-FRFSE]) or radial sampling (periodically rotated overlapping parallel lines with enhanced reconstruction [PROPELLER]). Their relative performance across breathing patterns is...
