ENHANCED DETECTION OF SEVERELY ISCHEMIC BUT VIABLE MYOCARDIUM . USING THALLIUM- GLUCOSE- INSULIN REINJECTION BY INFUSION METHOD

Abstract

Abstract: Because Thallium-201 kinetics, like potassium kinetics. It may be affected by serum insulin levels, we performed this study to identify severely ischemic myocardium using a new protocol based on the infusion of Thallium-201, insulin, potassium and glucose solution. Results are compared to the routinely done studies like stress Thallium-201and thallium-201 reinjection. These results confirm that continuous infusion of Thallium-201 with a low dose of insulin in a glucose/potassium chloride is safe and may enhance cellular uptake of the radiotracer in severe ischemic regions, thereby improving viable myocardium detection by more than 30% in comparison to the other routine techniques.
