CT Coronary Angiogram
+ Calcium Score

Computed Tomography (CT) coronary angiogram is used to check whether coronary artery is smooth or not, and to assess the severity of coronary artery narrowings calcifications. After scanning, a calcium score is derived to predict the probability of coronary artery disease.

CT coronary angiogram is the best non-invasive, anatomical test to visualize the walls and diameters of the coronary arteries. Based on the findings, the doctor will determine whether the patients need coronary stenting or coronary artery bypass grafting (CABG).
