Coronary Artery Perfusion Scanning with ¹³¹I-MAA Injected Directly into the Coronary Artery of Congenital Coronary Anomalies

Abstract

5μCi/Kg ¹³¹I-MAA was injected into the right coronary arteries in Cases 1, 2, and 3 under the diagnosis of right coronary artery fistula, and in Case 4 under the diagnosis of Bland-White-Garland syndrome. The results were compared with the angiocardiogram and right heart catheterization. When a fistula is small and cardiac cavity at the opening is not visualized by the angiocardiogram, coronary perfusion scanning successfully disclosed the location of fistula and influence of coronary circulation.
