The Coronary Artery Scan by Electron Beam Tomography (EBT) Coronary Artery Scanning is the most sensitive test for determining the presence and extent of the atherosclerotic process. A Coronary Artery Scan is capable of detecting and measuring calcium deposits (plaque build-up) in the major coronary arteries. The procedure takes less than l5 minutes and is painless and non-invasive (no needles or injections). The scan produces 30-40 images of the heart. Each image is taken in l00 milliseconds, approximately l5 times faster than the standard CT scan. The amount of x-ray dosage is approximately equal to one abdominal x-ray. Three electrodes will be attached to you to obtain the images at the proper cycling of your heartbeat. You will be instructed to hold your breath for short periods of time to eliminate respiratory motion. All images are analyzed by qualified radiologists and cardiologists for the presence of calcification in your coronary arteries. These results are then forwarded to you if you are a self-referred patient or to your physician if you are a physician-referred patient. HeartScan Imaging's program is designed for symptom-free men and women who fit the following criteria: Men, aged 40-65 and Women, aged 45-70 with at least one other risk factor*. *Risk Factors: Diabetes, cigarette smoking, overweight, family history of coronary artery disease, high cholesterol, high blood pressure The Chest Scan by Electron Beam Tomography (EBT) The Chest Scan involves scanning 100-140 thin 3mm slices through the entire volume of the lungs in a single 15 second breath-hold.  This test is usually recommended for smokers and requires a physician referral.  The images are interpreted by an expert board certified Radiologist.
