[Prostate cancer: anatomo-pathological correlation and MRI].
In our study, 50 patients had a prostatic carcinoma stade B. Before the radical prostatectomy we have realised a MRImaging of the prostate. After a precise histopathologic correlation we tried to appreciate the MRI performance for the detection of neoplasic nodes in the peripheral zone and for the loco-regional staging of the carcinoma. In detection of the pathologic nodes, MRImaging is more sensitive from the apex (22.5%) to the base of the prostate (91%), but it is at the same time specificless (apex: 90%, base: 40%). The accurate diagnostic for loco-regional staging in our study is 70%. Extracapsular extension is often underestimated because of the very small size of the invasion. On the other hand the specificity of MRI in seminal vesicles extension is satisfactory (87.5%).
