چکیده

Radiation exposure in cardiac imaging is a major healthcare concern and low-dose cardiac imaging has important implications for patients. We describe the application of a low-dose comprehensive cardiac computed tomography protocol that assesses anatomy, function, perfusion and viability with correlations to invasive coronary angiography and magnetic resonance imaging.

Comparison of transient ischemic dilation ratios in SPECT and SPECT-CT myocardial perfusion imaging in the low pre-test probability group

Introduction: The main purpose of this study was to compare transient ischemic dilation (TID) ratios in SPECT-low dose CT and SPECT Myocardial Perfusion Imaging (MPI) by application of different quantitative programs and quantify the possible shift in the upper normal limits of TID ratio in the SPECT-CT MPI. Methods: 149 Patients with low pre-test probability for coronary artery disease (CAD),...

CT myocardial perfusion imaging

Computed tomography (CT) is capable of comprehensively assessing the heart in order to provide information on anatomy, function, perfusion and viability. CT coronary angiography can assess both the coronary artery lumen and the characteristics of atherosclerotic plaques. CT myocardial perfusion imaging can provide additional information compared to CT coronary angiography by highlighting areas ...

Translation of Methdology used in Human Myocardial Imaging to a Sheep Model of Acute Myocardial Infarction

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...

Evaluation of Cardiac Function Using Fast Computed Tomography

Cardiovascular disease is a major cause of mortality in Western society but at its early phase may manifest as subtle alterations in coronary epicardial or microvascular function, including endothelial dysfunction, abnormal perfusion or permeability, and remodeling, which may precede clinical manifestation of vascular disease. These modifications might be associated with subclinical decline in ...
