Comprehensive evaluation of a Thorotrast patient: an overview

For several decades, thousands of people received Thorotrast during the course of angiography and other radiologic procedures. Eventually, as the hazards of this radioactive, radiographic contrast agent became apparent, research was initiated to further evaluate its associated adverse effects. In 1988 and 1989, Charles W. Mays, together with colleagues at a variety of sites, developed a detailed protocol for the comprehensive postmortem evaluation of one subject who had been administered Thorotrast 36 y previously. This case represents the first holistic approach to the analysis of Thorotrast in a whole body, simultaneously assembling clinical and autopsy findings with dosimetric, radiochemical, autoradiographic, and molecular evaluations.
