Radiation From Cardiac CT Scans Varies
Study Shows Many Centers Are Not Using Radiation-Lowering Strategies
CT Scan Advisory
On Monday the American Heart Association issued an advisory to doctors in its journal Circulation, urging the judicious use of CT scans for the diagnosis of cardiovascular disease.
Gerber, who led the panel that wrote the advisory, says doctors need to carefully consider whether patients with chest pain or other symptoms consistent with heart disease will benefit from the test before ordering it.
The advisory also warns against using CT scans to screen asymptomatic patients who are at risk for cardiovascular disease.
"This is already happening, but there are no studies that show that screening asymptomatic patients and then changing their treatment based on the results impacts survival," he says.
