title: The accuracy of tc-scan in the diagnosis of retroperitoneal metastases of malignant testicular tumours.
abstract: Based on the investigations carried out on 18 patients with testicular tumours, the results of CT-scanning are compared with the findings of conventional radiological examination and with lymphography in particular. At the actual state of technical evolution, the study reveals that CT-scanning does not possess sufficient spatial resolution to permit the diagnosis of very small lymph node metastases and all the more of a specific diagnosis of these metastases. Nevertheless, it remains a fact that CT-scanning obviously is a preferable method with respect to the visualisation of the exact extent and size of large involvements and the effects upon the surrounding tissues. CT-scanning is proposed as the screening-procedure with regard to patients suffering from testiscarcinoma, and allows, in a great number of cases, to make more invasive techniques superfluous.
