[Study of the coronary arteriole bed at rest and during hyperemia by selective coronary scintigraphy with labeled microspheres].
The hyperemic response induced by the tri-iodinated contrast agent injection for coronarography assesses functional value of the arteriolar areas of coronary distribution. The intracoronary injection of two kinds of micropheres labeled with gamma emitter radionuclides of different levels of energy (99m-Technetium and 113m-Indium) provides comparison of the studied areas-scintigraphies at rest and during hyperemia.
