Autor: Joseph M. Norris, Lucy A.M. Simmons, Abi Kanthabalan, Alex Freeman, Neil McCartan, Caroline M. Moore, Shonit Punwani, Hayley C. Whitaker, Mark Emberton, Hashim U. Ahmed

Publikováno v: European Urology Open Science, Vol 30, Iss , Pp 16-24 (2021)

Background: Multiparametric magnetic resonance imaging (mpMRI) has improved risk stratification for suspected prostate cancer in patients following prior biopsy. However, not all significant cancers are detected by mpMRI. The PICTURE study provides t
