Coronary artery evaluation. Coloured 3D computed tomography (CT) angiography scans of the coronary arteries of a 75-year-old woman, seen in four different views. This scan was done to evaluate the health of the coronary arteries (the arteries that supply blood to the heart) in a case of dilated cardiomyopathy. The arteries include the right coronary artery, and the left coronary artery (right) and its branches, the interventricular artery (the left anterior descending artery) and the circumflex artery. All the arteries shown are in good health with no stenosis (narrowing).
