Contrast Echocardiography
Ultrasound contrast agents are widely used in clinical practice for left ventricle opacification in sub-optimal echocardiograms. Recently, significant research has focused on the use of contrast echocardiography as a non-invasive means to evaluate myocardial perfusion. Advances in contrast agents as well as ultrasound technology have enabled investigations into myocardial contrast echocardiogra...
متن کاملDiffuse Pulmonary Arteriovenous Malformation in Children: Essential Value of Contrast Echocardiography in Diagnosis
Pulmonary arteriovenous malformations (PAVM) are abnormal communications between pulmonary arteries and pulmonary veins, and most commonly congenital in nature. Although rare, it is an important consideration in cyanotic patients of unknown cause. We report 3 cases with diffuse PAVM in children with different clinical manifestations and initial diagnosis was made by transthoracic contrast echoc...
متن کاملContrast echocardiography in myocardial infarction
The contrast agents used in ultrasound are approved for several clinical situations. New echocardiographic techniques, such as harmonic imaging and power pulse inversion imaging, can improve the visualization of microbubbles. In this article we discuss the early development of contrast echocardiography, new technologies that help improve image acquisition and its practical role in the assessmen...
متن کاملQuantification methods in contrast echocardiography.
New technologies and the availability of new echo-contrast agents have resulted in advances of diagnostic and prognostic indications of left ventricular opacification (LVO) and myocardial perfusion. The clinical diagnostic value of ultrasound contrast media for LVO and its impact on the clinical decision-making process has been demonstrated in several studies. Recent research aims at developing...
متن کاملMyocardial contrast echocardiography.
MCE has evolved from a laboratory tool to a clinical procedure. It would be wrong to consider it merely another tool for imaging of myocardial perfusion. As discussed, it allows physicians to bring physiology and pathophysiology to the bedside, providing a better understanding of the underlying mechanisms of abnormal findings in individual patients. MCE can provide quantitative measurements tha...
