EFFECT OF DIAGNOSTIC INTERMITTENT HIGH MECHANICAL INDEX IMPULSES ON GLOBAL LONGITUDINAL STRAIN IN PATIENTS BEING EVALUATED FOR SIGNIFICANT CORONARY ARTERY DISEASE

Intermittent high (IH) mechanical index (MI) impulses from a transcutaneous diagnostic transducer are used to improve endocardial border delineation and analyze myocardial perfusion during infusion of ultrasound enhancing agents (UEAs) These high MI impulses have also been shown to augment skeletal
