title: A randomized blind trial of iopamidol (Niopam) and Metrizamide (Amipaque) in lumber radiculography.
abstract: A randomised blind trial comparing Iopamidol (Niopam) and Metrizamide (Amipaque) for lumbar radiculography was performed in 100 patients. Significantly more patients receiving Metrizamide complained of having severe headaches (P less than 0.05) and vomiting (P less than 0.05). There was no difference in quality of the radiculograms.
