Abstract

Objective: Value of magnetic resonance imaging (MRI) was compared ​​with biopsy results of transrectal ultrasound-guided 12-core prostate biopsy. Subjects and methods: A total of 70 patients were examined by mpMRI and then transrectal ultrasound-guided 12-core prostate biopsy at E Hospital. Result of MRI were compare with histopathological data. Results: On T2-weighted imaging (T2W) 91,7% lesions showed hypointensity, 93,3% lesions in the transition zone and 90,1% lesions in the peripheral zone showed hypointensity. On diffusion-weighted imaging (DWI), the restricted diffusion in the peripheral  and  transition zones indicated PCa in 96,5% and 86,5% lesions. After dynamic contrast-enhanced (DCE) imaging, the early enhancement rate in the peripheral zone  was 89,5% lesions, higher  than in the transition zone at 73,0%. Invasion signs seminal vesicle invasion in 10 patients (34,5%), seminal vesicle and bladder neck invasion in 3 patients (10,3%). Pelvis node extension was observed in 7 patients (24,1%), and bone in 5 patients (17,2%). Conclusions: Our results showed that prostate cancer lesions often showed hypointensity on T2W, restricted diffusion on DWI, and early enhancement after DCE.
