Objective To compare the staging accuracy of transResults Endorectal coil MRI was more sensitive than TRUS for detecting both ECE, SVI and the site of ECE rectal ultrasonography (TRUS) and endorectal magnetic resonance imaging (eMRI) for organ-confined involvement in organ-confined prostatic carcinoma. TRUS was more accurate than eMRI for detecting the prostatic carcinoma. Patients and methods Twenty-five patients with clinisite of SVI involvement. However, the overall staging accuracy rates for both imaging modalities were equal. cally confined prostatic adenocarcinoma were evaluated to be candidates for radical prostatectomy. AllConclusions Neither TRUS nor eMRI was significantly better than the other for determining the local extent underwent TRUS and eMRI before surgery. Imaging findings evaluated prospectively in each patient of prostatic carcinoma. Therefore, TRUS should be the study of choice until MRI technology improves suBcwere extracapsular extension (ECE), seminal vesicle invasion (SVI) and the site of involvement.
