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...

BACKGROUND Although single photon emission computed tomography (SPECT) and positron emission tomography (PET) myocardial perfusion imaging (MPI) have evolved considerably over the last decade, there is no recent comparison of diagnostic performance. This study was designed to assess relative image quality, interpretive confidence, and diagnostic accuracy by use of contemporary technology and pr...

BACKGROUND Myocardial perfusion imaging (MPI) has been used in the assessment of chagasic heart disease. OBJECTIVE To investigate the value of gated-single photon emission computed tomography (gated-SPECT) MPI to detect early cardiac involvement in chagasic patients in the indeterminate phase, who present segmental motion abnormalities detected by tissue Doppler imaging (TDI)-derived strain. ...

We report a case of a young Indian male who had an incidental abnormal focal uptake of 99mTechnetium-MIBI (Methoxy Isobutyl Isonitrile) in the right lobe of thyroid while undergoing 99mTc-MIBI myocardial perfusion gated SPECT (Single Photon Emission Computed Tomography) imaging as a part of his myocardial ischemia status evaluation. This focal uptake was eventually detected to be a malignant th...

introduction: in patients with coronary artery disease (cad) noninvasive evaluation for detection of ischemia is important to avoid invasive interventions like angiography. exercise stress test is conventionally the first study used in evaluation of cad. considering the noninvasive nature of the myocardial perfusion scan, we decided to compare its accuracy with stress test. methods: patients wi...

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 ...

BACKGROUND The aim was to determine the sensitivity and specificity of gated myocardial perfusion SPECT (MPS) with a technetium-labelled (Tc) perfusion tracer to detect myocardial infarction (MI) in a clinical population referred for assessment of stress-induced ischemia using late gadolinium enhancement cardiac magnetic resonance (CMR) as reference method. METHODS 119 patients referred for e...

BACKGROUND The assessment of left ventricular function may be impaired by the abnormal interventricular septal motion frequently found after coronary artery bypass grafting (CABG). Studies on the validation of gated SPECT as a tool for the assessment of left ventricular function in this patient group are scarce. OBJECTIVE We investigated the agreement and correlation between left ventricular ...

BACKGROUND Ischaemic heart disease (IHD) is a major health problem today. However the focus has shifted primarily to angiographically detecting epicardial vessel stenoses, and ways and means of surgically correcting the blocks. Patients are often not fully evaluated for cardiac function, and diastolic dysfunction of heart, which is often an earlier manifestation than systolic dysfunction, goes ...
