title: Peridurography with metrizamide: animal and human studies.
abstract: Metrizamide (300 mg l/ml) was tested for spinal peridurography in conscious dogs and humans. Epidural metrizamide was non-irritating in volumes up to 12 ml. Larger volumes caused mild discomfort in two patients. Radiographic contrast was satisfactory, and there were no sequelae. Peridurography with metrizamide (300 mg l/ml) appears to be a safe, useful diagnostic procedure in ambulant patients.
