Dipyridamole thallium 201 imaging. How safe is it?
D ipyridamole thallium 201 scintigraphy is increasingly being used as an alternative to exercise scintigraphy for detection of coronary artery disease and risk stratification.1,2 Intravenous infusion of 0.56 mg/kg dipyridamole, the average dose used in clinical studies, causes a significant increase in myocardial blood flow in zones perfused by normal coronary arteries but only a slight increas...
متن کاملDipyridamole combined with exercise for thallium-201 myocardial imaging.
A new stress test for thallium-201 myocardial imaging in which pharmacological coronary vasodilatation with dipyridamole is combined with dynamic exercise is described. In 38 patients with coronary artery disease the sensitivity, total number of defects, degree of redistribution, and visual quality of thallium-201 imaging were greater after dipyridamole with exercise testing than after exercise...
متن کاملThallium-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 ...
متن کاملLung thallium-201 uptake during exercise emission computed tomography.
To test whether the analysis of lung uptake is worth adding to the interpretation of exercise thallium-201 (201TI) emission computed tomography (ECT), a lung/heart ratio of 201TI uptake was measured from an anterior image during ECT in 25 clinically normal (Group 1), 91 angiographically normal (Group 2), and 265 subjects with coronary artery disease (Group 3). The mean +2 s.d. of ratios in Grou...
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...
