Single-shot EPI (sshEPI) DWI has comparable the diagnostic performance of PC equivalent to sshEPI DWI using C-SENSE and multi-shot EPI (mshEPI) DWI called IRIS, whereas sshEPI DWI using C-SENSE and IRIS improve the image distortion and image blurringcompared to sshEPI DWI.
Details of the imaging parameters
A 80-year-old male with prostate cancer (PSA level of 13.69 ng/mL, Gleason score of 3+4) in the transitional zone. Cancer lesion is shown as a homogeneous hypointense lesion with mass effect on T2-weighted imaging (A). The lesion with focal hyperintensity is depicted clearly in the three DWI image (sshEPI DWI, sshEPI DWI using C-SENSE, and IRIS) (B, C and D). SNR and CNR is higher in sshEPI DWI than in sshEPI DWI using C-SENSE and IRIS, whereas sharpness in sshEPI DWI using C-SENSE and IRIS is better than sshEPI DWI.
