Abdominal imaging for critically ill patients requires a short breath-hold scan time. Volumetric Interpolated Breath-hold Examination (VIBE) is routinely used for the dynamic contrast enhanced studies for characterizing lesion in the abdominal organs such as the liver and the kidneys. To further reduce the scan time, phase partial Fourier is often employed. However, phase partial Fourier and echo asymmetry increase blurring in the in-plane view. In this abstract, phase correction with projection onto convex sets (POCS) is used with the VIBE sequence in order to reduce the blurring and maintain the image quality
