Gated myocardial single photon emission computed tomography (SPECT) is being used for the diagnosis of coronary artery diseases. In this study, we developed new software for the quantification of volumes and ejection fraction (EF) on the gated myocardial SPECT data using a cylindrical model. Volumes and EF by developed software were validated by comparing with those quantified by quantitative g...

BACKGROUND The cardiovascular disease is the main cause of death among diabetic patients, which makes it crucial to identify the individuals at higher risk of cardiovascular events. OBJECTIVE To evaluate the prognostic value of scintigraphy with gated single photon emission computed tomography (SPECT) in patients with diabetes mellitus (DM) and suspected coronary artery disease. METHODS Ret...

BACKGROUND The outcome of patients with severe ischaemic left ventricular (LV) dysfunction is determined by the extent of myocardial viability and the presence of LV dyssynchrony. We aimed at assessing both parameters from the same imaging method, i.e. gated positron emission tomography (PET) F18-fluorodeoxyglucose (FDG) scans. METHODS Phase analysis from Emory Cardiac Toolbox was applied on ...

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...

BACKGROUND Gated single photon emission CT (SPECT) sestamibi imaging allows the simultaneous assessment of myocardial perfusion and left ventricular function. OBJECTIVE The purpose of this study was to evaluate a technique for quantitative regional wall motion assessment using gated SPECT (99m)Tc-sestamibi imaging. PATIENTS AND INTERVENTIONS Fourteen subjects without cardiac pathology and 2...

INTRODUCTION AND OBJECTIVES Systolic function and myocardial perfusion are evaluated before hospital discharge and can change during follow-up. The purpose of this study was to evaluate these parameters by gated-SPECT in the first year after acute myocardial infarction. PATIENTS AND METHOD We studied 74 consecutive patients with a first uncomplicated acute myocardial infarction (49 infero-lat...

BACKGROUND The purpose of this study is to evaluate the feasibility, the image quality, and the clinical relevance of an early gated post-stress (GPS) single-photon emission computed tomography (SPECT) tetrofosmin (Myoview™-GE Healthcare) acquisition protocol. Time delay between myocardial technetium-labeled tracer administration and SPECT acquisition is usually about 30 minutes after stress, a...

UNLABELLED The prognostic power of myocardial perfusion imaging in patients with ischemic heart disease (IHD) has been demonstrated since planar imaging. We aimed to investigate whether gated SPECT retains this value in current cardiology if compared with a complete diagnostic work-up and with more recent prognostic indicators. METHODS We selected from our database a cohort of 676 consecutive...
