IMPORTANT NOTICE
This information is for educational purposes only, to facilitate quality conversations between patients and their personal physician(s). Several essential considerations are required to safely administer any protocol for an individual. This information is NOT intended to diagnose, treat or encourage self-treatment of any medical condition.
This test uses a CAT scanner to measure the amount of calcium in the coronary (heard) blood vessels. It has very good validity in predicting the degree of coronary artery disease (CAD, plaque). It can be a substitute in some cases for a stress test and/or angiography.
The only downsides is that the CAT scanner uses a good amount of radiation. Also the test is not covered by most insurances, costing ~ $200
