Atheroma plaques. Coloured 3D profile computed tomography (CT) scan of the abdomen of a 72 year old. The front of the body is at left. Many atheroma plaques (fatty deposits, pink) are seen lining the aorta (running down centre), the body's main artery. The plaques narrow the artery, raising blood pressure. Treatment is usually with either balloon angioplasty or a stent to re-open the artery.
