Epidurography using metrizamide an out-patient examination.

An improved technique of epidurography using metrizamide is described. Fifty patients were examined in order to establish whether the technique can be satisfactorily performed as an outpatient procedure and whether it is as useful as radiculography. The findings indicate that metrizamide epidurography is a safe examination, providing at least as much information as radiculography. Our patients tolerated the examination well, avoiding the after effects associated with intradural techniques, and were able to leave hospital a few hours later. No untoward sequelae occurred.
