Phase Contrast MRI (PC-MRI) offers unique advantages
over Doppler ultrasound for the quantification of
hemodynamics. However, lengthy scan times have limited
the clinical use of PC-MRI. We propose a Bayesian
inference technique to accelerate PC-MRI data
acquisition. The technique exploits the rich structure
inherent to the data across space, time and encodings.
Using 2D PC-MRI data from healthy volunteers,
performance of the technique is examined over a wide
range of acquisition times for prospective and
retrospective under-sampling. The proposed technique
provides an accurate recovery of peak and mean velocity
at accelerate rates of eight or higher with fast
computation.
