Hi. Cardiac CT for calcium scoring is a convenient and noninvasive way of evaluating whether you may be at increased risk for a heart attack. The exam takes little time, causes no pain, and does not require injection of contrast material.
Given your history, it may be caused by coronary stenosis. CCTA-calcium Scoring can be used to evaluate the degree of cardiovascular stenosis and determine the etiology of atrial fibrillation, chest pain and dizziness.
