title: [The clinical value of preoperative staging of bladder and prostatic cancers with nuclear magnetic resonance and computerized tomography].
abstract: To evaluate the diagnostic value of preoperative staging of bladder cancer and cancer of the prostate, CT and NMR scans of 45 histologically defined tumors of the bladder and the scans of 24 patients with radical prostatectomy were compared. Lack of extravesical spread was imaged correctly by NMR in all cases of urothelial cancer (pT1-pT3a). CT diagnosis failed in 39%. False-negative results were obtained in 2 of 5 invading tumors (pT3b) by NMR and in 3 of 5 by CT. Extraglandular spread of cancer of the prostate was diagnosed with an accuracy rate of 79% by NMR and of 46% by CT. The diagnostic value for detection of pelvic lymph node metastases had a low-sensitivity rate of 26% in NMR and of 22% in CT.
