A CT Angiography, a 64-slice multi-detector computed tomography scanner, is capable of cardiac imaging that examines the structure and vessels of the heart.

X-ray images along with the aid of a computer that generates cross-sectional views and 3-D images of the heart, a CT angiography exam is a non-invasive study that can assist your doctor in identifying soft plaque, or blockages, and calcium in the arteries. It also provides a precise look at the structure, shape and size of the heart.

If you have abnormal chest pain a cardiac CT angiogram might be performed as well to analyze your heart's structure to prepare for specific procedures.

The procedure is non-invasive compared to a heart cath and provides much more detailed anatomy of the coronary arteries than is obtained with other non-invasive procedures, such as stress tests.

Calcium Scoring

Calcium deposits can develop from plaque that has built up over time inside your arteries; this is called atherosclerosis or hardening of the arteries. During a cardiac CT exam, the initial image taken by the CT scanner determines your calcium score – a number indicative of the amount of calcium in your arteries.

The calcium score study also reveals the exact levels to scan for the CT angiogram study and can determine if you are someone who won't benefit from the angiogram study due to the large amount of calcium in your vessels.

Cardiac CT Angiogram

Once the calcium score is determined, the rest of the exam continues, and a contrast dye is injected into an IV. The contrast dye travels through the blood vessels and enhances images of your heart, making them more visible on the CT scan. The exam provides your doctor with information about cardiac risks and a detailed picture of coronary artery plaques to help in the diagnosis and treatment of coronary artery disease.

CT Angiography can help your physician to decide if your health care related issues can be managed with drug therapy, diet and exercise of if you need to be referred for cardiac catheterization for angioplasty and stenting.
