CT Scan: Computed Tomography

CT Scan: Computed Tomography

A CT scan uses X-ray technology to take multiple views of the inside of the body. Compared to regular X-rays, a CT scan can take clearer and more detailed images of organs, bone, soft tissue, blood vessels and other parts of the body.

Some of the primary uses for CT scans include:

Looking for bleeding inside the body, especially the in the skull
Studying the chest and abdomen
Determining the size and location of a tumor
Diagnosing skeletal problems
Diagnosing blood vessel diseases
Planning radiation treatments for cancer
Guiding biopsies and other tests
Planning surgery
Identifying injuries from trauma

CT Coronary Calcium Scoring

This single breath-hold, non-invasive, and fairly inexpensive CT scan can assess the extent of coronary artery calcium. Calcium scoring can help identify atherosclerosis of fatty buildup in the wall of the heart arteries, helping to determine your treatment and risk-reduction plan.

Candidates include men over 40 and women over 50 with risk factors for heart disease (diabetes, smoking, high blood pressure, high cholesterol, family history of heart disease), but no symptoms.

Insurance doesn't cover this procedure, which costs $150.00.
