[The diagnosis of bladder carcinomas by NMR tomography: an improvement with Gd-DTPA?].
85 patients suffering from urinary bladder carcinoma were examined by magnetic resonance imaging in a prospective study. Following precontrast diagnosis, 15 patients were given an intravesicular application of gadolinium-DTPA (Gd-DTPA). Another 35 patients received an intravenous bolus of GD-DTPA. A diagnostic advantage was achieved in only 2 of 15 tumours by using intravesicular contrast application. Compared to the precontrast diagnosis, a 14% improvement from 69% (precontrast) to 83% (contrast medium) was seen with Gd-DTPA applied intravenously in the diagnosis of the tumour stage. The diagnostic gain lies in the improved tumour recognition, the improved demarcation of papillary, non-muscle-infiltrating tumours and in the more definite diagnosis of infiltration into neighbouring organs and the pelvic wall. Demarcation of perivesicular fatty infiltration is rendered more difficult by Gd-DTPA.
