Evaluation of tumour extension by whole body scanner

Fifteen patients with urinary bladder carcinoma were examined by computerised tomography parallel with conventional urography before, during and after radiation therapy. Computer tomography gave better diagnostic information in the cases in which the tumour had encroached upon, or was growing outside the bladder wall, and was equally as valuable as urography when it was located wholly within the bladder. The scans were of great value as a guide in the planning of computer-aided radiation therapy.
