Americans undergoing myocardial perfusion imaging to diagnose coronary artery disease, a leading killer in the U.S., are receiving higher levels of radiation than their peers around the world, according to a new study.
The study was published in JAMA Internal Medicine this month.
The MPI test, performed on millions of U.S. patients every year, is a non-invasive imaging exam in which heart muscle blood flow is measured and areas with low flow are identified.
