Myocardial imaging with radionuclide-labeled particles. Analysis of the normal image, abnormal image, and technical...

Myocardial imaging following the direct injection of labeled particles is an effective and safe method of studying regional perfusion. Perfusion defects can conveniently be classified as apical, anterior, inferior, or posterior and related to the distribution of specific coronary arteries. The hemodynamic effects of contrast material, inadequate mixing of particles, coronary anatomy, and associated cardiac pathology are important technical considerations affecting the performance and interpretation of studies using this technique.
