Are spinal cord injury patients more prone to contrast reactions?

A previous investigation has indicated that spinal cord injury patients are more prone to develop reactions to intravenous contrast media. An investigation into the incidence of contrast reaction in 100 spinal cord injury patients undergoing intravenous pylography together with the incidence in a control group of 100 non-paraplegic patients, has been made. This has shown that spinal cord injury patients do not have a higher incidence of reaction. The aetiology of contrast reaction is briefly discussed with particular reference to the paraplegic patient.
