A coil sensitivity calibration technique for parallel
imaging that makes use of multiple free-breathing
prescans (MFP) to give accurate calibration data during
free-breathing, without reducing acceleration, is
compared with a temporal calibration technique in 20
prospectively subsampled first-pass myocardial perfusion
datasets.
