A comparison was made between the use of clinical methods and computed tomography for staging of carcinoma of the urinary bladder in 52 patients. CT was found to be the most reliable method for determining the perivesical extension of the tumour. It is of value for determining the extent of the tumour before irradiation and for establishing the tumour response. It was less reliable for diagnosing metastases in the lesser pelvis.

In routine postoperative observations on 31 transplanted kidneys, computed tomography (CT), ultrasonography (US) and gamma scintigraphy (GS) were compared with respect to diagnosis of abscess or lymphocele in the vicinity of the transplant, rejection and outflow obstruction. The results showed that US was the most reliable procedure for detecting fluid-filled cavities. In cases of graft rejection, GS was of most value. In demonstrating outflow obstruction, there was no definite difference between the three methods.
