[Value of nuclear magnetic resonance tomography in the diagnosis and stage determination of urinary bladder neoplasms].

We arrived at the following conclusions in our study on the ranking of magnetic resonance tomography in diagnosis and staging of urinary bladder neoplasms: MR tomography possesses high sensitivity but only low specificity in diagnosing the local spread of the tumour. Sensitivity of MR seems to be better in respect of determining the paravesical tumorous spread, than that of other methods. However, it is not possible to determine the tumour status of a space-occupying growth. No advantages of MR over other methods, especially computed tomography, were seen in the examination of lymph node metastases in the minor pelvis.
