Long-term prognostic value of exercise technetium-99m tetrofosmin myocardial perfusion single-photon emission computed tomography
BACKGROUND Exercise (99m)Tc-tetrofosmin single-photon emission computed tomography (SPECT) is a useful tool for short- and medium-term risk stratifications. Currently, the long-term prognostic application of this technique has not been evaluated. METHODS AND RESULTS Exercise (99m)Tc-tetrofosmin was performed in 655 consecutive patients. Ten patients who underwent revascularization <60 days af...
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 ...
متن کاملStress 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 کاملAdenosine Stress Induced Left Bundle Branch Block During Technetium-99m Tetrofosmin Myocardial Perfusion Imaging
The occurrence of left bundle branch block (LBBB) in electrocardiogram during exercise testing is a relatively rare finding. The incidence of LBBB during exercise testing ranges from 0.5% to 1.1%. The mechanism of exercise-induced LBBB (EI-LBBB) is poorly understood, but ischemia is a proposed etiology. Stress myocardial perfusion imaging (MPI) can be useful in patients with EI-LBBB to rule out...
متن کاملThe prognostic value of ECG-gated SPECT imaging in patients undergoing stress Tc-99m sestamibi myocardial perfusion imaging.
BACKGROUND The ability of stress radionuclide myocardial perfusion imaging to predict adverse cardiac events is well accepted. As left ventricular systolic function has also been shown to be an important prognostic indicator, the objective of this study was to determine whether electrocardiography (ECG)-gated single photon emission computed tomography (SPECT) functional data add additional powe...
