conclusions in this study there is no correlation between the main lv diastolic indices derived by spect and echocardiography, may be due to the main changes in the last version of guidline for assessment of lv diastolic function by echocardiography. results the population study consisted of 19 male and 30 female with the average age of 58.2 years.there is a mild negative correlation between pf...

Left ventricular (LV) function and volumes, along with myocardial perfusion, have major diagnostic and prognostic importance inpatients with coronary artery disease [4,11,13,14, 18,20,27]. Myocardial perfusion scintigraphy is a well-established technique for evaluation of myocardial perfusion [16,26,37,38]. Electro cardiographic gating during the acquisition of SPECT perfusion images has become...

UNLABELLED Fusion of images of vascular anatomy and of myocardial perfusion images might be helpful for understanding the relationship between ischemia and the responsible vessels. The aim of this study was to develop a simple means of superimposing the images obtained from coronary angiography and gated myocardial perfusion SPECT. METHODS Right and left oblique views from conventional corona...

UNLABELLED Quantitation of regional myocardial function is valuable in patients with coronary artery disease. This study assessed normal heterogeneity and developed and validated normal limits for quantitative regional motion and thickening by gated myocardial perfusion SPECT. METHODS Patients underwent rest (201)Tl/exercise (99m)Tc-sestamibi gated SPECT. Reference values of motion and thicke...

The development of quantitative gated single-photon emission computed tomography (SPECT) has enabled the assessment of left ventricular perfusion, function and wall thickness in a single examination. Accordingly, the present study used gated SPECT to assess the benefit of coronary artery bypass grafting (CABG) in patients with coronary artery disease; 47 of those patients were evaluated before ...

UNLABELLED Aim: Resistin plays a role in the pathogenesis of coronary artery disease and is related to mortality and morbidity through a number of mechanisms. We hypothesize that plasma resistin levels are increased in the presence of ischemia, as measured by GATED single- photon emission computed tomography myocardial perfusion scintigraphy (SPECT MPS), in comparison with nonischemic subjects....

BACKGROUND Patients with hypertrophic cardiomyopathy (HCM) sometimes develop subendocardial ischemia (SEI) in the left ventricle (LV). In the present study it was examined whether volumetric variables obtained by gated single-photon emission computed tomography (SPECT) are useful in detecting exercise-induced SEI in patients with HCM. METHODS AND RESULTS Exercise 99mTc-tetrofosmin myocardial ...

UNLABELLED The purpose of this study was to verify whether the accuracy of left ventricular parameters related to left ventricular function from gated-SPECT improved or not, using multivariate analysis. METHODS Ninety-six patients with cardiovascular diseases were studied. Gated-SPECT with the QGS software and left ventriculography (LVG) were performed to obtain left ventricular ejection frac...

BACKGROUND In contrast to 201TlCl, 99mTc-sestamibi shows very slow myocardial clearance after its initial myocardial uptake. In the present study, myocardial washout of 99mTc-sestamibi was calculated in patients with non-ischemic chronic heart failure (CHF) and compared with biventricular parameters obtained from first-pass and ECG-gated myocardial perfusion SPECT data. METHODS AND RESULTS Af...
