It remains a challenge to diagnose the oligometastatic prostate cancer (PCa) due to the ambiguous definition of oligometastatic PCa. Previous studies had shown that dynamic contrast enhanced (DCE) - MRI imaging could be used to assess tumor aggressiveness. This study indicated that transfer constant (Ktrans) had the potential to assess the aggressiveness of PCa. And Ktrans combined with clinical characteristics (such as age and prostate specific antigen) had the higher diagnostic efficiency for oligometastatic and widely metastasis PCa.
