title: Medical and economic considerations in using a new contrast medium.
abstract: In deciding to use a new intravascular contrast medium, the considerations should be patient safety, Imaging efficacy, and cost. Balancing these factors, use can be estimated. With the new low-osmolality contrast media, particularly the nonionic media, the expected increased patient safety must be balanced against the much higher cost.
