Myocardial Viability Imaging
The concept of hibernating myocardium originated from observations in the 1970s that the myocardial dysfunction seen in patients with chronic coronary artery disease (CAD) was not always permanent (1). The fact that revascularization with coronary artery bypass grafting (CABG) could result in the recovery of contractile function in previously akinetic segments led to the development of numerous...
متن کاملMyocardial viability assessment using nuclear imaging.
Myocardial assessment continues to be an issue in patients with coronary artery disease and left ventricular dysfunction. Nuclear imaging has long played an important role in this field. In particular, PET imaging using 18F-fluorodeoxyglucose is regarded as the metabolic gold standard of tissue viability, which has been supported by a wide clinical experience. Viability assessment using SPECT t...
متن کاملMR imaging of myocardial perfusion and viability.
CMR is a rapidly developing new modality with applications in clinical cardiology for detection and assessment of myocardial ischemia and viability. CMR perfusion results for the detection of ischemia in comparison with stress echocardiography and scintigraphic techniques are reasonable, but all the studies reported to date have been conduced in selected patients. Larger studies in patient popu...
متن کاملMyocardial Viability Imaging using HYPR-based MRI Techniques
INTRODUCTION Assessing myocardial viability in patients with coronary artery disease and left ventricular dysfunction can be critical to determine which patients might benefit from revascularization [1]. Delayed-enhancement MR imaging (DE-MRI) has shown promise in distinguishing healthy myocardium from infarcted myocardium since infarcted myocardium exhibits higher signal than normal myocardium...
متن کاملAssessment of Myocardial Viability with Magnetic Resonance Imaging
Accurate assessment of myocardial viability is a central goal in clinical diagnosis of ischemic heart disease, as well as in basic research into the underlying mechanisms of cardiac pathology. Clinical assessment of myocardial viability would have a significant impact on the management of patients with ischemic heart disease, by avoiding unnecessary revascularization procedures, as well as asse...
