  • Title: Urological applications of computerized axial tomography: a preliminary report.
    Author: Stewart BH, James R, Haaga J, Alfidi RJ.
    Journal: J Urol; 1978 Aug; 120(2):198-204. PubMed ID: 671635.
    Abstract:
    Computerized tomography scanning of the chest and abdomen has been used as a diagnostic technique in more than 4,500 patients since 1974, 190 of whom had histologically proved disorders of the genitourinary system and retroperitoneum. On the basis of this experience computerized tomography scanning has been found to be safe and effective, and offers certain advantages over conventional techniques. The number, extent and content of renal mass lesions can be determined with relatively great accuracy. The presence and extent of metastases into the retroperitoneum, liver and chest can often be shown by computerized tomography scanning when other tests are negative. Placement of needles for aspiration, biopsy, injection of contrast medium or insertion of drainage tubes can be done more accurately under computerized tomography control. Computerized tomography in itself is non-invasive, carries a low radiation exposure comparable to other radiographic procedures and therefore, can be valuable in following the course of patients with various diseases during and after therapy. While scanning will not replace other diagnostic procedures it should lead to a more judicious selection of potentially hazardous tests in selected cases, such as angiography, aspiration and open biopsy.
