A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease.Specifically, it looks for calcium deposits in atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. [1]
Widow maker is an alternative name for the anterior interventricular branch of the left coronary artery. [9] [3] The name widow maker may also apply to the left coronary artery [10] or severe occlusions to that artery. [11] [12] This term is used because the left main coronary and/or the left anterior descending supply blood to large areas of ...
Specifically, it looks for calcium deposits in the coronary arteries that can narrow arteries and increase the risk of heart attack. [17] This severity can be presented as Agatston score or Coronary Artery Calcium (CAC) score. The CAC score is an independent marker of risk for cardiac events, cardiac mortality, and all-cause mortality. [18]
Dr. Rohit Vuppuluri, DO, FACC, RPVI, a vascular cardiologist in Chicago, Illinois, says that one way to know how much coronary calcification you have is by getting a coronary calcium scan. “A ...
Typically, coronary artery disease occurs when part of the smooth, elastic lining inside a coronary artery (the arteries that supply blood to the heart muscle) develops atherosclerosis. With atherosclerosis, the artery's lining becomes hardened, stiffened, and accumulates deposits of calcium, fatty lipids, and abnormal inflammatory cells – to ...
Endoscopic optical coherence tomography, also intravascular optical coherence tomography is a catheter-based imaging application of optical coherence tomography (OCT). [1] It is capable of acquiring high-resolution images from inside a blood vessel using optical fibers and laser technology.
The calcification deposits, [74] after they have become sufficiently advanced, are partially visible on coronary artery computed tomography or electron beam tomography (EBT) as rings of increased radiographic density, forming halos around the outer edges of the atheromatous plaques, within the artery wall.
Specifically, it looks for calcium deposits in the coronary arteries that can narrow arteries and increase the risk of a heart attack. [60] A typical coronary CT calcium scan is done without the use of radiocontrast, but it can possibly be done from contrast-enhanced images as well. [61]
