[Caudal radiography versus computerized axial tomography in the diagnosis of lumbosacral radiculitis].

The advantages and disadvantages of caudoradiography and computed tomography in the diagnosis of compressive sciatic radiculitis are compared. With this in mind, the data on 103 patients admitted to Giaveno Hospital in 1986-1987 are analysed. In this series 99 were subjected to CAT scans, 21 to caudoradiculography (7 to both examinations) and 41 to surgery. Apart from revealing the advantages and defects of the two techniques, the results confirm the preference for CAT expressed elsewhere in the literature.
