The image quality and diagnostic performance of diffusion weighted imaging (DWI) using multiplexed sensitivity encoding (MUSE) and DWI using reduced field-of-view (rFOV) technique in detecting prostate cancer were compared. Visual scores of MUSE-DWI regarding the visibility of prostate anatomy and overall image quality were significantly higher than those of rFOV-DWI. The diagnostic performance in detecting prostate cancer was not significantly different between MUSE-DWI and rFOV-DWI. MUSE yielded high quality DWI without reducing FOV and is expected to be more useful than rFOV technique for evaluation of the prostate including lymph node metastasis.
