Evaluation of the PI-RADS v2.1 Score Using Multiple Readers

"1. Ass of targeted suspect lesions~ On each mpMRI,radiologist will contour lesions that were targeted at subsequent biopsy based on reports. Contours will be disclosed to readers who will assess,for each lesion:~ * Likert score(gut feelingie subjective ass of the likelihood that lesion is clinically significant prostate cancer(5-level scale))~ * PI-RADSv2, PI-RADSv2.1 score(by strictly applying the published PI-RADS criteria)~ * EPE score(ie the likelihood of extraprostatic extension;5-level subjective scale without predefined criteria)~ * Max diameter~2. Def of add suspect lesions Readers could define suspectadditional targets(AT);for each AT,they will provide the same criteria. It is expected that, for these suspect AT,at least one score is≥3~3. Ass of lobes Scores of prostate lobes will be automatically calculated based on 2 previous steps of reading. However,in lobes with no suspect lesion,readers could define whether same criteria are1or2,in peripheral zone and transition zone"
