Hara et al. [24] in order to evaluate DWI for the diagnosis and localization of recurrent PCa after definitive EBRT retrospectively analyzed 10 patients with BF (PSA range: 2.06–7.36 ng/mL) using histological findings from 22-core 3-dimensional prostate mapping biopsy as a standard reference. Here, KLK3 is linked to posterior cortical atrophy.
