Iodine-123-Rose bengal: An improved hepatobiliary imaging agent.

Abstract

A practical method for preparing )23-I-rose bengal that allows for its rapid and efficient incorporation into the molecule is reported. Administration of 123-I-rose bengal to normal healthy patients showing the normal uptake and excretory pattern visualized with this radio pharmaceutical is also presented. The overall reduction in imaging time and radiation exposure together with the improved images possible should greatly improve our diagnostic capabilities in evaluating the jaundiced patient.
