“…It is suggested that in addition to ADC image texture and shape information, its own features and ADC values also have certain diagnostic value. The research of Xu ( 26 ) and Zhang ( 27 ) has proven this conjecture.…”

“…Finally, texture analysis could further stratify PI-RADS 3 lesions into indolent or clinically significant PCa (csPCa) nodules, thus avoiding unnecessary biopsies [ 12 , 19 , 21 ]. The paper published by Hectors et al [ 12 ] showed a sensitivity and specificity of 75% and 79.6%, respectively, with an AUC of 0.76 regarding the detection of csPCa among PI-RADS 3 lesions ( p = 0.022), while mpMRI alone registered a sensitivity of 38.24% and a specificity of 53.85% for PI-RADS 3 tumors [ 34 ].…”

“…It has been shown that the diagnostic accuracy of prostate MRI examinations can be improved by considering PSA density, quantitative image criteria such as mean ADC values and radiomic features, as well as by using new techniques like MR fingerprinting and machine learning (11,13,(20)(21)(22)(23)(24). Furthermore, 68Ga-PSMA PET/CT also showed good accuracy in the primary diagnosis of csPCa and could be used additionally in case of uncertainty whether a biopsy should be performed or not (25) CDR of PI-RADS categories ≤2 are very low, independently from PSAD (4).…”

“…Zhang et al proposed a downgrading algorithm for PI-RADS ≥4 lesions with an mADC cut-off at a threshold value of 732 μm 2 /s (13). By applying this downgrading algorithm, they achieved to increase specificity and accuracy without sacrificing sensitivity for detection of csPCa (ISUP >1) in their patient cohort.…”
