Cardiovascular imaging of remote myocardial ischemia: detecting a molecular trace of evidence left behind.
Intravenous microbubbles currently are approved by the Food and Drug Administration solely for the purpose of enhancing left ventricular cavity opacification. However, intravenous microbubbles also have been used in several clinical studies to detect myocardial perfusion. Ultrasound imaging of myocardial contrast to detect perfusion abnormalities has significant advantages over other imaging te...
متن کاملDiagnostic Value of Ankle Brachial Index for Myocardial Ischemia in Asymptomatic Diabetic Patients and Comparison with Myocardial Perfusion Imaging
Objective: The ankle-brachial index (ABI) as a simple test which can detect peripheral arterial disease (PAD). Therefore in this study we try to evaluate the diagnostic value of ABI for silent myocardial ischemia in diabetic patients and compare the results with myocardial perfusion imaging (MPI) results. Materials and Methods: All 149 diabetic patients in this study were categorized according...
متن کاملmasked ischemia on myocardial perfusion imaging: a case example
discussion the reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. there may be other findings on mpi images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. another important issue is the ecg changes during exercise stress testing, wh...
متن کاملDetecting left ventricular myocardial ischemia during intravenous dobutamine with cardiovascular magnetic resonance imaging (MRI).
Advances in computer software, scanner hardware, and hemodynamic monitoring equipment have permitted the development of cardiovascular stress testing protocols for use during intravenous Dobutamine infusions within magnetic resonance imaging (MRI) scanners. Recent studies have documented that the safety profile and clinical utility of Dobutamine/Atropine cardiac stress testing during MRI compar...
متن کاملDynamic myocardial CT perfusion imaging for evaluation of myocardial ischemia as determined by MR imaging.
OBJECTIVES The aim of this study was to determine the feasibility of computed tomography (CT)-based dynamic myocardial perfusion imaging for the assessment of myocardial ischemia and infarction compared with cardiac magnetic resonance (CMR). BACKGROUND Sequential myocardial CT perfusion imaging has emerged as a novel imaging technique for the assessment of myocardial hypoperfusion. METHODS ...
