A person who is very large may not fit into the opening of the CT scanner or may be over the weight limit of 650 lbs. for the moving table.

CAD, especially in people below 50 years of age can be present without calcium (non-calcified plaque) and may not be detected by this exam.

Health insurance plans do not typically cover cardiac CT for calcium scoring screenings. Since this is a screening exam it is not covered by Medicare and Medicaid.

A high heart rate may interfere with the image quality of the test. If a patient's heart rate is 80 or more beats per minute, the exam may need to be rescheduled.

Exactly how your treatment or prevention for heart attacks should be modified according to your calcium score remains uncertain.
