Detection of occult thymoma during exercise thallium 201, technetium 99m tetrofosmin imaging for coronary artery disease.
Thallium (Tl) 201 and technetium (Tc) 99m tetrofosmin single-photon emission CT are routinely used in the evaluation of coronary artery disease. Mediastinal tumors demonstrate Tl 201 and Tc 99m tetrofosmin uptake. We report a 56-year-old man who developed chest pain after a previously successful angioplasty and stent of the left anterior descending coronary artery. He underwent a Tl 201, Tc 99m...
متن کاملMyocardial technetium-99m-tetrofosmin and technetium-99m-sestamibi kinetics in normal subjects and patients with coronary artery disease.
UNLABELLED This study was designed to compare the tracer kinetics between 99mTc-sestamibi and 99mTc-tetrofosmin in a heterogeneous group of 24 patients admitted for routine perfusion imaging. METHODS Twelve patients were studied with 99mTc-tetrofosmin and 12 with 99mTc-sestamibi. In each group, six patients had a low likelihood for coronary artery disease, and six patients had angiographicall...
متن کاملComparison of technetium-99m tetrofosmin and thallium-201 single-photon emission computed tomographic imaging for detection of myocardial perfusion defects in patients with coronary artery disease.
OBJECTIVES We compared dipyridamole technetium-99m (Tc-99m) tetrofosmin and thallium-201 (Tl-201) single-photon emission computed tomographic (SPECT) imaging with respect to the detection rate of perfusion abnormalities in 26 patients with angiographic coronary artery disease (CAD). BACKGROUND Experimental studies have shown that myocardial extraction of Tc-99m tetrofosmin is lower than that ...
متن کاملMyocardial perfusion scan accuracy in detection of coronary artery disease - Comparison with exercise stress test [Persian]
Introduction: In patients with coronary artery disease (CAD) noninvasive evaluation for detection of ischemia is important to avoid invasive interventions like angiography. Exercise stress test is conventionally the first study used in evaluation of CAD. Considering the noninvasive nature of the myocardial perfusion scan, we decided to compare its accuracy with stress test. Methods: Patie...
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...
