A CT scan is a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, organs, and blood vessels. CT scans are more detailed than standard x-rays.
CT scans may be done with or without contrast. “Contrast” refers to a substance taken by mouth or injected into an intravenous (IV) line that causes the particular organ or tissue under study to be seen more clearly. Contrast examinations may require you to fast for a certain period of time before the procedure. Your physician will notify you of this prior to the procedure.
CT scans may be performed to help diagnose tumors, investigate internal bleeding, or check for other internal injuries or damage.
CT Heart Scan(Calcium Scoring)
Doctors use heart scans to check for calcium deposits in your heart’s coronary arteries. Calcium deposits, known as plaque, can narrow your arteries and increase your risk of heart disease. This quick and painless CT (computed tomography) scan of your heart measures your coronary calcium score which can indicate whether you have a higher risk of having a heart attack before any symptoms of heart disease occur. This inexpensive test provides valuable information about your heart health.
CT Lung Scan
Following the National Lung Screening Trial (NLST) criteria, this low-dose CT scan provides the best way to detect lung cancer before symptoms appear. If you are a current or former smoker between ages 55 and 74, talk to your doctor to see if you may benefit from screening. Few or no symptoms occur in the early stages of lung cancer. It is the number one cause of cancer deaths in the US. Recent studies have shown that low-dose CT scans are two-and-a-half times more effective than general x-rays at finding lung abnormalities. However, abnormality does not necessarily mean cancer.
