NOVEL APPLICATIONS OF MCE (MYOCARDIAL CONTRAST ECHOCARDIOGRAPHY) IN CORONARY ARTERY DISEASES WITH DIFFERENT SITUATIONS

Myocardial contrast echocardiography (MCE )can be a feasible alternative to the widely used radionuclide single-photon emission computed tomography (SPECT), which is often limited by higher costs, exposure to radiation, poor spatial resolution and frequent attenuation artefacts.MCE is useful to detect coronary artery disease on basis of myocardial perfusion. Many studies have demonstrated concordance between MCE and SPECT for assessment of Myocardial Perfusion during rest and stress. Myocardial contrast echocardiography also provides higher sensitivity as well as incremental prognostic value over and above Wall Motion in patients with stable coronary artery diseases (CAD). Importantly, the higher sensitivity of MCE over Wall Motion is independent of the type of stress modality used.
