Abstract:
Harmonic and fundamental imaging techniques were directly compared in 20 patients undergoing intravenous contrast echocardiography for enhancement of left ventricular endocardial border definition. Harmonic imaging demonstrated significantly enhanced left ventricular endocardial border detection and improved the duration and intensity of a contrast effect despite a reduced dosing requirement.

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...
