A detailed TPM analysis of cardiac function necessitates high spatio-temporal resolution which leads to prolonged scan durations. These scan times are typically too long for data acquisition within a single breath hold. Respiratory navigator-gating can compensate breathing-related motion, but causes an additional increase in measurement time and images with residual motion artifacts. The aim of this study was to combine UNFOLD with variable density spiral SPiRIT TPM to achieve an additional scan time reduction by a factor of 2 and an effective undersampling factor of 6. UNFOLDed SPiRIT TPM demonstrates good results and enables scan times within very short breath holding.
