OBJECTIVES This study assessed the impact of cardiac risk assessment using gated single-photon emission computed tomography (SPECT) on cardiac events in end-stage renal disease (ESRD) patients. METHODS We evaluated 215 asymptomatic patients who began dialysis between January 2005 and April 2009. Baseline electrocardiography and echocardiography were performed in all the patients. The subjects...

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...

Myocardial normal databases for stress myocardial perfusion study have been created by the Japanese Society of Nuclear Medicine working group. The databases were comprised of gender-, camera rotation rangeand radiopharmaceutical-specific data sets from multiple institutions, and normal database files were created for installation in common nuclear cardiology software. Based on electrocardiograp...

introduction: it is recommended that the physician apply at least a semi-quantitative segmental scoring system in myocardial perfusion spect.  we aimed to assess the agreement between automated semi-quantitative analysis using qps (quantitative perfusion spect) software and visual approach for calculation of summed stress  score (sss), summed rest score (srs) and summed difference score (sds). ...

OBJECTIVES It is widely accepted that exercise-induced stunning has an impact on left ventricular ejection fraction (EF); yet, despite the recommendations of the American Society of Nuclear Cardiology, many departments only perform gated SPECT on stress studies. The aim of this investigation was to determine the relationship between rest EF and stress EF in myocardial perfusion studies and to i...

introduction: the relationship between depression and coronary artery disease is well established; however assessment of this relationship using functional and semi-quantitative imaging (myocardial perfusion scintigraphy) was lacking. the aim of this study was to assess the relationship between the severity of depression and the severity of myocardial perfusion abnormality. methods: patients we...

Abstract Background False negative myocardial perfusion images on single-photon emission computed tomography (SPECT) imaging (MPI) is a substantial problem in the interpretation of MPI. To explore possible parameters from gated SPECT that could detected coronary artery disease (CAD) patients with normal images, we retrospectively selected who underwent 2-day Tc-99 m MIBI adenosine stress/rest M...
