Comparison of Cardio Vascular Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) for Detection of Myocardial Viability
Coronary artery disease (CAD) remains the most common cause of death. However, the number of deaths from myocardial infarction has decreased. Mortality from congestive heart failure has more than doubled. It is important to note that CAD accounts for the majority (almost 70%) of congestive heart failure cases.
In the clinical management of patients with symptom of heart condition by CAD, the correct assessment of cardiac muscle viability is crucial to guide treatment and this will be as a result of revascularization of dysfunctional however viable heart muscle can improve cavity perform and future survival.
Generally nuclear imaging, stress echocardiography and stress electrocardiography have been the clinical main step for assessing myocardial viability as well as to detect myocardial Ischemia.
Recently cardiovascular MR (CMR) is a rapidly emerging non-invasive imaging technique, providing high resolution images of the heart in any desired plane and without radiation. CMR has the unique ability to evaluate several markers of myocardial viability that are of proven value. The focus of the present study is on the rapidly emerging clinical role of cardiovascular MRI in the detection of viable myocardium.
Objective: To assess the role of cardiovascular MRI for detection of myocardial viability
