A new technique was developed to perform fast
acquisition of 4D flow in abdominal vessels. By
combining undersampled spiral sampling and dynamic
compressed sensing reconstruction, 4D flow could be
acquired in significantly shorter time, down to a breath
hold. In 5 subjects, the novel technique shows high
correlation with a standard Cartesian 4D flow
measurement and good agreement with 2D phase contrast.
Accelerated spiral 4D flow has high potential for
comprehensive assessment of hemodynamics in a clinically
acceptable scan time.
