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 stress imaging in hypertensive patients.
To assess the potential effect of hypertension on the results of thallium-201 stress imaging in patients with chest pain, 272 thallium-201 stress tests performed in 133 hypertensive patients and 139 normotensive patients over a 1-year period were reviewed. Normotensive and hypertensive patients were similar in age, gender distribution, prevalence of cardiac risk factors (tobacco smoking, hyperl...
متن کاملDipyridamole Thallium Imaging
Thallium e01 Tl) myocardial perfusion imaging with exercise is widely accepted as a simple and safe method to diagnose coronary artery disease (CAD) or to evaluate the extent and significance of disease in patients with known CAD. A significant number of patients cannot achieve the necessary level of exercise with routinely performed 201 Tl treadmill or bicycle exercise testing to properly allo...
متن کاملPrognostic value of dipyridamole-thallium myocardial scintigraphy in patients with Kawasaki disease.
BACKGROUND Although coronary artery lesions are critical complications of Kawasaki disease, their long-term outcome is still unclear. It is sometimes difficult to monitor progressive changes from aneurysms to stenotic lesions because coronary angiography (CAG) cannot be repeated very often, especially in infants. Our prospective study was designed to evaluate the prognostic value of dipyridamol...
