Due to the distinct ghosting artifacts, in Tissue Phase Mapping (TPM), inflowing blood causes phase errors corrupting the velocity information in Cartesian velocity-encoded acquisitions. Suppression of these phase errors demand blood suppression [1], causing a reduction of the temporal fidelity of the cine data. The different point-spread function in radial data acquisition causes less distinct artifacts and may lead to less velocity corruption enabling white-blood TPM imaging. This contribution compares the degree of corruption in black- and white-blood TPM for Cartesian and radial velocity measurements.
