Stress thallium-201/rest technetium-99m sequential dual isotope high-speed myocardial perfusion imaging.
OBJECTIVES Our purpose was to describe a novel, rapid stress thallium-201 (Tl-201)/rest technetium-99m (Tc-99m) agent myocardial perfusion imaging (MPI) protocol (Tl/Tc) with a high-speed MPI scanner and to compare this protocol with a standard rest/stress Tc-99m agent protocol (Tc/Tc) with respect to image quality and radiation dosimetry. BACKGROUND Recent advances in gamma camera technology...
متن کاملThe value and throughput of rest Thallium-201/stress Technetium -99m sestamibi dual-isotope myocardial SPECT.
Myocardial perfusion scintigraphy is an established method in cardiology for the diagnosis and evaluation of coronary artery disease (CAD). Thallium-201 and Tc-99m sestamibi myocardial perfusion imaging has been widely accepted as non-invasive diagnostic procedure for detection of CAD, risk stratification and myocardial viability assessment. But, standard Tl-201 redistribution and same day or 2...

متن کاملMyocardial perfusion imaging with technetium-99m-Tc NOET: comparison with thallium-201 and coronary angiography.
UNLABELLED We compared TcN-NOET [bis(N-ethoxy, N-ethyl dithiocarbamato)nitrido 99mTc] and 201Tl images to estimate the utility of this compound in the detection of coronary artery disease (CAD). METHODS Twenty-five patients undergoing cardiac catheterization had stress-redistribution-reinjection 201Tl SPECT imaging, stress-delayed (2, 4 and 6 hr postinjection) and rest-delayed (4 hr postinjec...
متن کاملTechnetium-99m-Teboroxime: A New Agent for Myocardial Perfusion Imaging
The assessment of myocardial perfusion by nuclear scintigraphy is an important diagnostic tool for the evaluation of patients with ischemic heart disease. Although a variety of radiopharmaceuticals have been used to assess coronary blood flow, thallium-201 ( 01 Tl) has become the most commonly used imaging agent since its introduction for clinical use by Lebowitz eta!. in 1973 (J). Thallium-20 ...
