Accuracy of cardiac CT, radionucleotide and invasive ventriculography, two- and three-dimensional echocardiography, and SPECT for left and right ventricular ejection fraction compared with cardiac MRI: a meta-analysis.
AIMS Left ventricular ejection fraction (LVEF) and right ventricular ejection fraction (RVEF) are important tools in clinical decision-making. We hypothesized that two-dimensional echocardiography (2DE), three-dimensional echocardiography (3DE), radionucleotide ventriculography (RNV), cardiac computed tomography (CT), gated single-photon emission CT (SPECT), and invasive cardiac cine ventriculo...
متن کاملEvaluation of left ventricular wall motion, volumes, and ejection fraction by gated myocardial tomography with technetium 99m-labeled tetrofosmin: a comparison with cine magnetic resonance imaging.
BACKGROUND Whether left ventricular function can be assessed accurately by gated single photon emission computed tomography (SPECT) in patients with myocardial infarction and severe perfusion defects is not well known. METHODS AND RESULTS Twenty-five patients with an acute myocardial infarction underwent 99mTc-labeled tetrofosmin (99mTc-tetrofosmin) gated SPECT and cine magnetic resonance ima...
متن کامل4D cardiac MRI in the mouse.
With the introduction of mouse models for the study of cardiac morphogenesis, there arises a need for new imaging protocols that can capture both morphological and functional information. High-resolution 2D cardiac cine MRI has often been used to quantify left and right ventricular function. In this study we propose a 3D isotropic cardiac cine MRI protocol with a voxel size of 200 microm(3) as ...
متن کاملComparison of 201Tl, 99mTc-tetrofosmin, and dobutamine magnetic resonance imaging for identifying hibernating myocardium.
BACKGROUND Both radionuclide perfusion tracers and contractile response to dobutamine have been used to identify hibernating myocardium. The aim was to compare 201Tl (thallium) single photon emission CT (SPECT), 99mTc-tetrofosmin (tetrofosmin) SPECT, and dobutamine cine MRI for identifying regions of reversible myocardial dysfunction. METHODS AND RESULTS Thirty patients with 3-vessel coronary...
متن کاملCo-registration of cardiac MRI and rest gated SPECT in the assessment of myocardial perfusion, function and viability.
PURPOSE Myocardial perfusion is routinely measured by SPECT--this technique has a rather low spatial resolution but covers the whole myocardium and is equipped with efficient image analysis software. Cardiac MRI has higher spatial resolution than SPECT and excellent sequences for myocardial function and viability detection but the lack of easy-to-use methods of acquisition and post-processing o...
