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.
