Single-shot EPI (sshEPI) DWI still suffers from distortion and blurring. Multi-shot EPI (mshEPI) DWI called IRIS and sshEPI DWI using C-SENSE (a combination of parallel imaging and compressed sensing) enables to reduce distortion and blurring. A total of 14 prostate cancer (PC) patients underwent mpMRI including sshEPI DWI, IRIS, and sshEPI DWI using C-SENSE under the same scan time. The sshEPI DWI has comparable the diagnostic performance of PC equivalent to sshEPI DWI using C-SENSE and IRIS, whereas sshEPI DWI using C-SENSE and IRIS improve the image distortion and image blurring compared to sshEPI DWI.
