Demographic and lesion characteristics of N = 112 patients. All patients underwent two prostate MR examinations (SA and SB) performed on the same day approximately 15 min apart following repositioning on MR scanner table

Axial images refer to each 2D axial slice of the whole prostate volume. Each image is considered as positive if a clinically significant prostate cancer (csPCa) lesion exists on the image or is considered as negative
