The use of MCE for viability assessment is based on the principle that microvascular integrity is a fundamental prerequisite for myocardial viability. 23 Myocardial contrast enhancement can be observed only if the coronary microvasculature is preserved and perfusion defects indicate a disrupted coronary : Melissa Leung, Dominic Y Leung. Myocardial contrast echocardiography (MCE) Intracoronary contrast administration has emerged as a modality for assessing myocardial perfusion, and it has the potential to predict myocardial viability. Basis: Myocardial contrast enhancement depends on an intact microcirculation. Traditionally nuclear imaging, stress echocardiography and (stress) electrocardiography have been the clinical mainstays for assessing myocardial viability as well as to detect myocardial ischaemia. However, cardiovascular MR (CMR) is a rapidly emerging non‐invasive imaging technique, providing high‐resolution images of the heart in any Cited by: As such, PET has been proven invaluable to the noninvasive investigation of cardiovascular biology and physiology. Assessment of myocardial perfusion and substrate metabolism are of particular value in the evaluation of patients with (suspected) coronary artery disease (CAD) to detect ischemia and myocardial viability.
Your doctor has ordered a myocardial viability PET scan to measure myocardial glucose metabolism using FDG. Our team of specialized doctors, nurses and technologists is led by Alan Waxman, MD, Chief of Nuclear Medicine. Before Your Exam. Do not eat or drink caffeine products (chocolate, soda, tea, coffee or Excedrin®) for 24 hours before exam. The myocardial uptake of thallium is a sarcolemmal membrane Na/K ATPase-dependent active process requiring cell membrane integrity, and is therefore indicative of myocardial viability. Thallium uptake by myocytes is also a reflection of regional perfusion (required for delivery of tracer to the myocyte) and viability. A Nuclear Medicine Thallium Viability Scan is a test used to evaluate the blood flow to the heart. After a heart attack (myocardial infarction), some of the heart muscle may be permanently damaged or scarred. Once this occurs, the area affected will cease to function properly. Other parts of the heart may be injured, but not permanently scarred. As a result, myocardial viability has captured the imagination of researchers and clinicians seeking to unravel the cellular and subcellular mechanisms and define appropriate diagnostic modalities. These diagnostic modalities include: cardiac catheterization, positron-emission tomography, magnetic resonance imaging, two-dimensional.

VAN DER WALL The first edition of this book was published in Since then important advances have occurred in the field of myocardial viability. This, coupled with increasing interest by the scientific community in the broader issues of its relevance to patient care, suggested to us the need to write the second. Second, in comparative studies with thallium reinjection and PET imaging with FDG, most myocardial segments that were identified as viable by reinjection had metabolic evidence of myocardial viability. 67 – 69 The concordance between data on thallium reinjection and FDG uptake was excellent, with 51% of regions with severe irreversible.
