Recently non-invasive imaging study of spinal canal had been well developed, but as for lumbar disease, examination with radio-opaque media is still needed in many cases. Lumbar peridurography is one of them which can be done in out-patient clinic easily. Sodium iothalamate has so far been used in many cases, but it sometimes causes severe pain during and after procedure. We have been using iohexol for lumbar peridurography since October 1987. 81.4% of patients in the group using iohexol (group 1) showed excellent or good contrast, and 68.4% of those using iothalamate (Group 2). Concerning about pain during and after procedure, only 10.9% of group 1 patients complained moderate or severe pain, whereas the rate was 35.8% in group 2. We concluded that iohexol gives more benefit than iothalamate in lumbar peridurography. We also discuss about Computed Tomography after lumbar peridurography, regarding to its diagnostic usefullness. It proved to be useful in making diagnoses in a few cases.
