What are the limitations of Cardiac CT for Calcium Scoring?

A person who is very large may not fit into the opening of a conventional CT scanner or may be over the weight limit—usually 450 pounds—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.

Not all health insurance plans cover cardiac CT for calcium scoring.

A high heart rate may interfere with the image quality of the test.

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

EBCT scanners have fewer rows of detectors and lack the spatial resolution of the latest generation CT scanners.
