We evaluated a combination of SENSE acceleration and compressed sensing in the MR simulation workflow to reduce scan time and improve image quality and anatomical coverage. Imaging series were performed with SENSE-only and with a combined SENSE+compressed sensing (CS) software package. CS resulted in an average reduction of 28% in single-series scan time with negligible changes in image quality and the ability to contour structures for RT treatment planning. In addition, CS permitted pulse sequence modifications which reduced respiratory artifacts, improved visibility of the prostatic urethra, and eliminated the need for a Foley catheter in prostate cancer patients.
