Studies Raise Questions About Echocardiography

Larry Husten, PHD

Echocardiography is a safe, noninvasive tool to image the heart without the use of radiation. For this reason it has become the most frequently used method to look at the heart for a wide variety of medical indications. Now two new studies suggest that, despite its popularity, transthoracic echocardiography is often not beneficial. One study […]
