Magnetic resonance imaging in staging of locoregional prostate cancer: comparison of results with analysis post-surgical histopathology.

Conventional staging for locoregional prostate adenocarcinoma has been demonstrated as potentially underdiagnosing. Therefore, prostate MRI is emerging as an important tool for staging before surgery. Advanced techniques such as diffusion and dynamic contrast enhancement also contribute to increasing its accuracy. In this preliminary study, MRI was compared with prostate histopathology samples, reaching 78% sensitivity and 100% specificity for tumor localization; 33% sensitivity and 100% specificity for extracapsular extension; 100% sensitivity and 100% specificity for involvement of the seminal vesicles. It is possible to believe that these preliminary results are promising, and more cases will tend to confirm these data.
