Abstract:
Myocardial contrast echocardiography is an noninvasive and promising method for the assessment of myocardial perfusion. At the beginning, the contrast agents were administered intracoronary but now the second-generation contrast agents contain microbubbles that traverse the pulmonary circulation and opacity the myocardium after intravenous injection of contrast. The sensitivity, specificity and diagnostic accuracy of myocardial contrast is comparable with perfusion nuclear studies. The myocardial contrast echocardiography is currently the best and most accurate measure of reperfusion at a microvascular level, specially the assessment of non-reflow phenomenon after acute myocardial infarction.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
