Axial (a) and coronal (b) T2w imaging, high b value (c), ADC map (d) and pre-contrast (e) and DCE acquisitions (f) of a study that was given a PI-QUAL score of 3. At least two MR sequences taken together are of diagnostic quality: although T2w imaging is of good diagnostic quality, some parameters are not compliant with the PI-RADS v.2.1 technical recommendations such as the field of view for DWI (23 × 31 cm in c, d—please note that the DWI images here are magnified) and the temporal resolution (17 s) of DCE sequences. The arrows indicate a lesion (Likert 4/5) in the left peripheral zone between 4 and 5 o’clock. Targeted biopsy revealed Gleason 3 + 4 disease
