CT Heart Scans Controversial

Computed tomography (CT) scans of the heart are becoming more popular. The scans also are called CT angiograms. Like an angiogram, they allow an inside view of blood vessels. But the test is not invasive. Advocates say it can find heart disease in people with no symptoms. But critics say there’s no proof it improves care or saves lives, the New York Times reported June 30. The test also is costly and exposes the patient to many times the radiation of a regular X-ray. Experts told the Times that this test is an example of the growth of new technology before its benefits have been proven.
