[Irradiation of the patient and its costs in the usual diagnostic procedures for disk hernia. Radiculography, spinal phlebography and tomodensitometry].
Three methods are currently employed for the diagnosis of sciatica due to disc lesions: radiculography, spinal phlebography, and computed tomography. Though their indications vary according to the author, it seemed worthwhile to compare radiation delivered by each of them, because of the often young age of the patients. Dosimetric studies using a Rando Phantom enabled calculation of doses to the skin, spinal cord, and gonads. Results indicated that low doses were delivered by the scanner, relatively high doses by spinal phlebography, and intermediate doses by radiculography. These findings suggest that the initial examination preoperatively in cases of simple sciatica due to herniated disc should be a CT scan whenever possible. Phlebography, on the contrary, and particularly in young women, should be used only exceptionally, as a result of the high doses delivered to the ovaries even during technically simple explorations.
