Transient Ischemic Dilatation Ratio in Stress Myocardial Perfusion SPECT in Diabetic Patients-A Systematic Review and Meta-Analysis
Abstract Objective: Abnormal values of the transient ischemic dilation (TID) ratio are associated with severe and extensive coronary artery disease (CAD). TID can be used as a diagnostic and prognostic marker of CAD in diabetic patients. The aim of current study was to determine the pooled estimate of TID ratio in single myocardial perfusion scan in diabetic patients by a systematic review and...
متن کاملComparison 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),...

متن کاملPrognostic significance of ischemic electrocardiographic changes during adenosine infusion in patients with normal myocardial perfusion imaging.
BACKGROUND The development of ST-segment depression during adenosine myocardial perfusion imaging (MPI) has been shown to be an independent predictor of subsequent cardiac events and worse outcome, particularly in association with ischemic defects. However, the prognostic significance of ST-segment depression with adenosine in patients with normal MPI is not known. METHODS AND RESULTS We perf...
متن کاملPerfusion imaging using rubidium-82 (82Rb) PET in rats with myocardial infarction: First small animal cardiac 82Rb-PET
Assessing myocardial perfusion using Rb-PET is emerging as a valuable clinical tool. The rapid decay (T = 76 s) allows for absolute quantification of both rest and stress perfusion within 30 minutes. In addition to evaluation of epicardial disease with perfusion defects, also evaluation of balanced coronary and small vessel disease is possible. For further evaluation of how Rb-PET can be used c...
