title: Positron emission tomography. The technique and its applications to the study of the cardiovascular system.
abstract: The technical features of positron computed tomography are reviewed, and the positron-emitting tracers of flow and metabolism and their relation to physiologic processes are described. The authors report some of their clinical experience with this new modality and emphasize areas of pediatric disorders of the heart that are likely to benefit from positron computed tomography.
