The benefit of using radial instead of Cartesian readouts for MS-CAIPIRINHA accelerated myocardial perfusion measurements was explored. Conjugate gradient SENSE was used to determine fully sampled data for the two slices acquired simultaneously. A phantom study was performed first, which revealed lower g-factors for radial MS-CAIPIRINHA in comparison to a corresponding Cartesian acquisition. Finally, saturation-recovery-prepared and ECG-triggered radial MS-CAIPIRINHA was applied for perfusion investigations of the myocardium in a healthy volunteer.
