Widespread clinical use of phase contrast MRI is
restricted due to this modalities low data acquisition
efficiency. Low efficiency may lead to low temporal and
spatial resolution within a clinically acceptable breath
hold. Compressed sensing in combination with low Rank
Block Wise constraint is a promising strategy in
increasing acquisition efficiency. The goal of this
study is to characterize the efficacy of Low Rank Block
Wise reconstruction by reconstructing retrospectively
undersampled data, and comparing maximum velocity
measure from reconstruction to maximum velocity obtained
from fully sampled data sets. Agreement between maximum
velocities will be achieved by using Bland Altman plots.
