BACKGROUND The aim of this study was to assess the prognostic value of technetium-99m tetrofosmin gated SPECT imaging in women using quantitative gated single photon emission computed tomography (SPECT) imaging. METHODS We followed 453 consecutive female patients. Average follow-up was 1.33 years (max. 2.55). Hard endpoints were cardiac death, acute myocardial infarction, or documented ventri...

Introduction: Myocardial perfusion imaging using gated SPECT and phase analysis is an effective tool in evaluation of mechanical dyssynchrony. The purpose of this study was to determine the normal ranges of global and regional phase parameters. Methods: A total of 100 patients with normal resting and stress electrocardiograms, low pretest likelihood for c...

PURPOSE Inferior attenuation is a common problem in the interpretation of myocardial perfusion SPECT. We explored whether cardiovascular magnetic resonance (CMR) was a useful adjunct in differentiating between artifactual attenuation of the inferior wall and the presence of myocardial infarction and/or ischemia. METHODS We used CMR to assess resting wall motion, myocardial perfusion, and the ...

Background. We prospectively investigated whether adenosine 2`TI tomography (SPECT) could determine the extent of coronary artery disease, the presence ofjeopardized myocardium, and the risk for in-hospital cardiac events in 120 clinically stable patients early (5±3 days) after myocardial infarction. Methods and Results. All patients had coronary angiography and SPECT in close proximity. Adenos...

background: pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. the aim of this study was to evaluate whether spect/ct myocardial perfusion imaging (mpi) could be used for assessing sheep myocardium following an acute myocardial infarction (mi) and response to int...

BACKGROUND Myocardial perfusion gated single photon emission computed tomography (SPECT) can be used for non-invasive detection of coronary artery stenosis and cardiac allograft vasculopathy (CAV), which is a crucial factor for the long-term survival of heart transplant (HTx) recipients. A frequently observed finding in myocardial perfusion imaging of patients after HTx is inhomogeneous myocard...

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...

INTRODUCTION AND OBJECTIVES The aim of this study was to compare magnetic resonance and gated-SPECT myocardial perfusion imaging in patients with chronic myocardial infarction. METHODS Magnetic resonance imaging and gated-SPECT were performed in 104 patients (mean age, 61 [12] years; 87.5% male) with a previous infarction. Left ventricular volumes and ejection fraction and classic late gadoli...

OBJECTIVES The purpose of this study was to determine how frequently and for what reasons the addition of electrocardiographically gated technetium-99m (Tc-99m) sestamibi single-photon emission computed tomographic (SPECT) images add value to nongated SPECT perfusion images. BACKGROUND Electrocardiographic gating of Tc-99m sestamibi SPECT images permits assessment of regional and global left ...
