Background: proper assessment of patients with ischemic cardiomyopathy is a key determinant for management other investigations, improving the patient’s quality life and reducing future cardiac events. This study was conducted to evaluate value myocardial MIBI washout rate using delayed resting perfusion imaging in limited resources countries. Patients Methods: this prospective included 86 (64 ...

PURPOSE OF THE REPORT The aims of this study were to compare perfusion and functional parameters between early (ES) and standard (SS) post-stress gated SPECT MIBI, to validate ES against coronary angiography, and to determine whether ES parameters can predict future cardiac events. PATIENTS AND METHODS The sample included 63 patients with normal or mildly impaired left ventricular function an...

Although single photon emission computed tomography (SPECT) is preferable for myocardial perfusion scintigraphy, in a minimal number of circumstances, planar imagingmay be useful ormay be the onlymodality available. Purpose. To evaluate regional myocardial perfusion and function. Planar imaging is an acceptable method for myocardial perfusion imaging. The anatomy of the heart is sufficiently si...

Myocardial ischemia may occur during an exercise session in cardiac rehabilitation programs. However, it has not been established whether it is elicited when exercise prescription is based on heart rate corresponding to the anaerobic threshold as measured by cardiopulmonary exercise testing. Our objective was to determine the incidence of myocardial ischemia in cardiac rehabilitation programs a...

OBJECTIVE In this study, we describe a new technique for three-dimensional registration of CT coronary angiography (CTCA) and gated myocardial perfusion SPECT. METHODS Twelve patients with known or suspected CAD who underwent CTCA and gated SPECT were enrolled retrospectively. Coronary arteries and their branches were traced using CTCA data manually and reconstructed in three-dimensions. Gate...

Background. The aim of this study was to assess the prognostic value of technetium-99m tetrofosmin gated SPECT imaging in patients with left bundle branch block (LBBB) using quantitative gated single photon emission computed tomography (SPECT) imaging. Methods and Results. We followed 101 consecutive patients with LBBB using technetium99m tetrofosmin gated SPECT imaging. Average follow-up was 1...

BACKGROUND The phenomenon of reversible impairment in LV function has been well described and is known as myocardial stunning. OBJECTIVE Thallium-201 myocardial perfusion gated SPECT was used to evaluate myocardial stunning and its incremental prognostic value in patients with coronary artery disease. PATIENTS AND METHODS Fifty-six patients (aged 63+/-11 years) with coronary artery disease ...

Introduction: Gated SPECT myocardial perfusion scanning has new capabilities in addition to its main applications such as left ventricular dyssynchrony using phase analysis. Phase analysis has been investigated through various software including Emory Cardiac Toolbox (ECTb) and Quantitative Gated SPECT (QGS). The aim of this study is to evaluate the effect of reconstruction par...

OBJECTIVES The aim of this research was to evaluate kinetics and extent of myocardial contrast enhancement (CE) in comparison with single-photon emission computed tomography (SPECT) early after acute myocardial infarction (AMI). BACKGROUND Quantification of infarct size serves as a surrogate end point in evaluating new therapies of AMI. Contrast-enhanced magnetic resonance imaging (CeMRI) of th...
