Echocardiography

Cardiac ultrasound uses reflected sound waves (echos) to create images of anatomy inside the body. Echocardiograms are the primary cardiac imaging modality used to assess the heart and diagnose or track cardiac issues. Echo is the gold standard imaging modality to assess the heart, particularly with calculating left ventricular ejection fraction (LVEF), which is a measure of cardiac output. In addition to noninvasive standard transthoracic echo (TTE), invasive transesophgeal echo (TEE) is also used when clearer, more detailed imaging of the heart is needed. Both 3D and 4D echo echo systems are rapidly gaining wider adoption and enable new types of assessments, especially in the structural heart space and in transcatheter procedural guidance.

ASE: Biomarkers may predict chemo-related cardiotoxicity

According to research presented during the 21st annual scientific sessions of the American Society of Echocardiography (ASE) in San Diego this week, cardiac troponin plasma concentrations and longitudinal strain can predict the development of cardiotoxicity in patients treated with anthracyclines and trastuzumab chemotherapies.

ASE recommends contrast agent usage in echoes

The American Society of Echocardiography (ASE) has issued a consensus statement, supporting the use of contrast agents used to enhance echocardiogram images, and providing a guide for physicians who may be hesitant to use the contrast agents following a 2007 FDA black-box warning. The statement was published in the November issue of Journal of the American Society of Echocardiography.

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.
