T2-WI 4/4

All met

1Adequate SNR throughout axial T2-WI 2Relevant prostatic structures clearly delineatedCapsule, ejaculatory ducts, NVBs, external urethral sphincter 3No significant artifact in the prostatic regionMotion, blurring, signal loss, ringing, wrap-around 4Sagittal/coronal T2 has adequate SNR, resolution, and no significant artifact

Technical prerequisite

3 mm slices

DWI 4/4
