Thallium-201 Myocardial Perfusion Imaging
The sensitivity of myocardial perfusion imaging (MPI) using thallium-201 injected both at rest and during peak exercise was compared to simultaneously recorded 12 lead electrocardiography (ECG) for the detection of transient ischemia in 20 normal subjects and 63 patients with coronary artery disease (CAD). No significant perfusion defects or ECG changes were seen on either the rest or exercise ...

Thallium-201 Myocardial Perfusion Scintigrams in the Evaluation of Aortocoronary Saphenous Bypass Surgery In a recent article, Verani et al. (/) reported the effect of aortocoronary bypass grafting (ACBG) on regional myocardial perfusion, using thallium-20! imaging after exercise. At the present time there is considerable controversy about ACBG and the way in which angina is relieved by this op...
متن کاملThallium-201 for myocardial imaging. Relation of thallium-201 to regional myocardial perfusion.
Following intravenous administration, the myocardial concentration of tracer thallium-201, potassium-43, and rubidium-81 were determined in mice; thallium was present in the greatest concentration in the myocardium (2.08% compared 1.25% for potassium and 1.15% for rubidium at 10 minutes). The regional myocardial distribution of thallium-201 was determined in dogs under conditions of normal flow...

a D t t H w l c T t l t a e 9 2 r t c A i “ e 9 n a s t s r m m p i Thallium-201 has several virtues as a myocardial perfusion agent. It is one of the best of the soluble agents for measuring regional myocardial perfusion, because it has a blood clearance half-time of 30 s and a first pass extraction in the myocardium of 88% (1) (compared with the 1-min blood clearance half-time [2] and 50% to ...
متن کاملTomographic Thallium-201 Myocardial Perfusion Scintigrams After Maximal Coronary Artery Vasodilation with Intravenous Dipyridamole Comparison of Qualitative and Quantitative Approaches
Eighty-six patients had thallium-201 (20'Tl) myocardial perfusion scintigrams after intense coronary artery dilation with i.v. dipyridamole. The dipyridamole was infused at 0.15 mg/kg/min for 4 minutes. Significant side effects were infrequent. Coronary angiography showed that 24 of our 86 patients had normal coronary vessels or 30% luminal obstruction in one coronary artery; 11 patients had a ...
