How Does a Coronary Calcium Scan Work?

A coronary calcium scan is one done with a CT scan. We often call it the mammogram of the heart, because in the similar a way, we're scanning for hidden disease. It actually has the same amount of radiation as a mammogram, it takes less time, it's actually less painful, there's no pain at all, it's minimal radiation and instead of finding hidden lumps, it finds hidden plaque in our arteries that if we don't do something about, they'll eventually cause a heart attack or a stroke.
