Non-contrast myocardial perfusion assessment in porcine acute myocardial infarction using arterial spin labeled CMR
Background Following acute myocardial infarction (AMI), microvascular integrity and function may be compromised as a result of microvascular obstruction (MVO) and vasodilator dysfunction [1,2]. It has been observed that both infarct and remote myocardial territories may exhibit impaired myocardial blood flow (MBF) patterns associated with abnormal vasodilator response [3]. Arterial spin labeled...
متن کاملMyocardial perfusion using arterial spin labeling CMR: promise and challenges.
c i d B t Arterial spin labeling (ASL) magnetic resonance imaging (MRI) is a noncontrast technique that can quantify tissue blood flow. It is most commonly applied to the brain (1) and kidney (2); however, it also has potential application to other organs, including the heart (3). Used for the heart, ASL might eventually play a role in cardiac pharmacological stress testing, where it could be u...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Arterial Spin Labeled Perfusion MRI
Perfusion refers to the delivery of oxygen and nutrients to tissues by means of blood flow and is one of the most fundamental physiological parameters. Disorders of perfusion also account for most of the leading causes of medical disability and mortality. While measurements of perfusion are of direct diagnostic value in vascular disorders, perfusion measurements also serve as biomarkers for a b...
متن کاملAssessment of coronary endothelial function using blood oxygenation level dependant cardiovascular magnetic resonance imaging (BOLD-CMR) in a canine model
Background Endothelial function is important in the pathogenesis of atherosclerosis. Whereas endothelial function of peripheral circulation can be assessed non-invasively with Flow-Mediated Dilatation, no method exists for coronary circulation. BOLD-CMR utilizes inherent contrast, where the signal intensity (SI) is linearly correlated with the regional tissue level of deoxygenated hemoglobin. T...
