PC-MRI is commonly acquired using interleaved
flow-compensated (FC) and flow-encoded (FE) echoes. We
hypothesize that the FC data, which represents
background phase, does not change significantly over
time in certain applications, such as common carotids
artery. Therefore, we proposed to under-sample the FC
data and use a view-sharing approach (FCVS) to
synthesize a composite FC frame for each corresponding
FE frame. FCVS was evaluated in prospective in vivo
study with six healthy volunteers and compared with a
standard FCFE PC-MRI on peak velocity and flow
measurements.
