Multiparametric MRI (mpMRI) of the prostate can detect clinically significant prostate cancer in men. To accelerate the time-consuming acquisition process, we integrated a new Compressed SENSE (CS) method for T2-weighted sequences with propeller acquisition and compared it qualitatively and quantitatively to conventional SENSE accelerated T2-weighted propeller sequences. We could demonstrate that while the new CS acquisition method has less artifacts, better image sharpness and higher apparent signal-to-noise ratio (aSNR) and contrast-to-noise ratio (CNR), it reduced the acquisition time by 24%. These findings indicate a superiority over the conventional T2-sequence and could improve the diagnostic workup of patients with prostate cancer.
