Interactive method of informing patients of the risks of intravenous contrast media.

Purpose: To evaluate interactive computer-based informed consent for use of contrast material versus the same information in a written format.

Materials And Methods: Patients (n = 160) referred for radiologic examination with intravenous contrast material were block randomized (sex, age, and previous exposure to contrast material) into two groups and were provided either written or computer-based (video) informed consent.

Results: The female patients in the video group scored better on the test than those in the group with the written consent form.
