Graph shows coronary calcium scores in asymptomatic men. The small red block represents the percentage of people with the same age and sex of the presented patient who have less calcium in the coronary arteries. The relatively high calcium score in combination with other cardiac findings in this patient would be a good indication for referral of the patient to a cardiologist before surgery.

In a semi-automated fashion, the dynamic images from 0% to 90% of the cardiac cycle were used to calculate ejection fraction (end-diastolic volume minus end-systolic volume) and the end-diastolic myocardial mass of the left ventricle.
