S. Duboistoussaint et al., PROSTATIC-CARCINOMA - CORRELATION OF HISTOPATHOLOGIC FINDING AND MR-IMAGING, Journal de radiologie, 76(4), 1995, pp. 179-184
In our study, 50 patients had a prostatic carcinoma stage B. Before th
e 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 periphera
l zone and for the loco-regional staging of the carcinoma. In detectio
n 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 s
pecificless (apex: 90%, base: 40%). The accurate diagnostic for loco-r
egional 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 sat
isfactory (87.5%).
