Abstract
- To evaluate the impact of the addition of quantitative apparent diffusion coefficient (ADC) data into the diagnostic performance of the Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) scoring system to predict clinically significant prostate cancer (CSPCa). We retrospectively included 91 consecutive patients who underwent prostate multiparametric magnetic resonance imaging (mp-MRI) and histopathological evaluation. Mp-MRI images were reported by the PI-RADSv2 scoring system and patients were divided into groups considering the likelihood of CSPCa. ADC value and ratio were obtained. Findings were correlated with histopathological data. CSPCa was found in 41.8% of cases (n = 38). PI-RADSv2 score 3–5 yielded a sensitivity of 97.4% (95% confidence intervals 86.5–99.5), a specificity of 50.9% (37.9–63.9), and AUC of 0.74 (0.67–0.81) to predict CSPCa. ADC value
