Coronary artery calcium scoring uses X-ray techniques to detect calcification in coronary arteries, a feature of advanced atherosclerosis.

“so coronary I'll see a coronary calcium score is a CT scan that's done dry meaning without any contrast so you lay on the CT table and it's a very quick scan and because there's no contrast anytime you see something that's really really bright white in there which is normally what color contrast would be you know it's calcium so there's a scoring system where you can actually get some anatomic detail not to the degree of understanding how much narrowing there is of the arterial lumen but you can see which arteries so the left main artery the circumflex artery the left anterior descending the right artery the posterior descending artery and the amount of calcification is then scored and ranked against a percentile”

“coronary calcium is a an important step forward in cardiovascular Imaging and it's a process where you can accurately and and pretty safely determine using x-ray techniques whether there's calcium bone in the coronary arteries and calcification is part is a feature of advanced aosc crosis”
