Also known as angiography or arteriography, this special x-ray helps to detect if your coronary arteries are blocked, where, and by how much.
The researchers interviewed 200 patients who were undergoing a diagnostic test called angiography, an X-ray exam of the blood vessels and heart chambers that can determine if a person has coronary heart disease.
This is a special kind of angiography procedure that's specifically designed to examine the blood vessels in the heart and how they respond to different medications.
Another use would be before painful procedures such as angiography, balloon angioplasty, and the insertion of venous catheters.
Yet doctors are reluctant to do an invasive test, such as angiography, which sends a probe into the heart and has its own dangers, Einstein said.
But abnormal results from that test, which are common in healthy people, often lead to additional tests, including CT angiography.
John McEvoy, a heart specialist at Johns Hopkins Hospital and the lead author, said doctors are looking for "optimum use" of a non-invasive imaging test called coronary computed tomographic angiography, called a CCTA test and also known as CT angiography.
"Our findings suggest that low-risk patients without symptoms don't benefit in the short term from knowing whether or not plaque has been detected using CT angiography," Dr. McEvoy said.
Vincent Staub contended that he was fired from his job as an angiography technician because his immediate supervisors objected to the time he missed because of his duties as a member of the Army Reserve.
Techniques include all of those required to perform state-of-the-art diagnosis including computed tomography, magnetic resonance imaging, magnetic resonance angiography and spectroscopy, as well as functional MRI and MEG.
