Offering New Levels of Excellence in CT

Coronary Heart Disease (CHD) is the leading cause of death in most of the world. To help avoid it, experts recommend that people learn the risks for heart disease, be tested and diagnosed as early as possible, and begin treatment as soon as they can. Imaging techniques such as cardiac CT are just one tool doctors use to examine the heart and determine a patient’s risk for developing heart disease.

The SOMATOM Sensation Cardiac 64™ takes CT scanning to new levels, employing the latest and fastest technology to create clear, detailed images of your body that will help your doctor make the best diagnosis, and best treatment, for you. This is a non-invasive procedure that is performed in less than 10 minutes and provides valuable information regarding patency of the coronary arteries and deposition of calcium in these vital blood vessels of the heart.

New Level of Speed

Engineered for speed and accuracy so a complete exam of the heart can take as little as 10 minutes, from scan to diagnosis. * Previously, patients suspected of heart attack might undergo a stress test, EKG study, and blood testing, which could take much longer.?Allows doctors to evaluate the most common causes of acute chest pain with a single scan.?Permits some patients to avoid surgical procedures such as cardiac catheterization.?*Results may vary. Data on file.

New Level of Comfort

64-slice technology requires that you hold your breath for shorter periods than older, 16-slice technology—for example, a scan of the blood vessels in your heart now requires that you hold your breath for 9 seconds, compared to 17 seconds with 16-slice equipment.

New Level of Clarity

The SOMATOM Sensation Cardiac 64 provides excellent image quality, regardless of your size and weight. Images the beating heart in real time, permitting evaluation of its valves and the motion of its walls in greater detail.

New Level of Versatility

The SOMATOM Sensation Cardiac 64 can also be used when studying Cardiovascular conditions, including stroke and blood clots and other conditions involving the brain, colon, or lungs.


Frequently Asked Questions

What is a CT Scan?

Computed tomography (CT), also referred to as computerized axial tomography (CAT), is an x-ray technique that uses a special scanner and a computer to create cross-sectional images of the body. Unlike standard x-rays, which take a two dimensional projected picture of the part of the body being examined, the CT has the ability to image that same structure as a series of cross-sectional images. The CT Scan produces clearer, more detailed images of the part of the body being examined than can be accomplished by x-rays and is the preferred cross-sectional imaging test in most cases for examination of the chest, abdomen, pelvis, sinus, ear and some bones.

What is a 64-Slice CT Angiogram?

An “angiogram” generally refers to a medical imaging study that is used to look at arteries in the body. The purpose of an angiogram is to usually to determine if there is narrowing in arteries or some other disease that may impair blood flow. Narrowing of arteries is often due to atherosclerosis. The term angiogram can be confusing as there are two types of angiogams that can be performed, and each can be used to look at arteries and veins throughout the body. The two main classes of angiograms may be referred to as “catheter” angiograms and “non-invasive” angiograms, which include CT (computed tomography) and MRI (magnetic resonance imaging) angiograms. Catheter angiograms have been present for a longer period of time, and refer to a study where dye is injected into the bloodstream through a vein or artery using a catheter (a small plastic device). A physician then evaluates the arteries and veins by looking at 2-dimensional X-ray images of the blood vessels. Catheter angiograms are still the diagnostic test of choice under certain conditions. The downside to a catheter angiogram is that it is more invasive to the patient and sedation is used. Catheter angiograms have a higher risk of serious adverse events, including rupturing a blood vessel and infection. Although the risks are more serious, they occur relatively infrequently. 64 Slice CT angiograms refer to angiograms completed using computed tomography technology. These studies are increasing in use because of the excellent image quality. 64 Slice CT coronary angiograms were previously performed using catheter techniques until recent advances in 64 slice CT technology allowed for high quality images. Coronary arteries supply the heart itself with blood, and an insufficient supply of blood may lead to a heart attack. A physician usually orders an angiogram to determine the severity of narrowing of the arteries. If there is narrowing of the coronary arteries, for example, a physician may suggest coronary artery bypass surgery or the placement of a stent to ensure that there is adequate blood supply to the heart. The advantage to using a 64 slice CT scan versus catheter angiography is that the physician does not need to insert a catheter directly into a vein or artery to inject dye. Instead of inserting a catheter into a large vein or artery and advancing the catheter to the area being studied, the physician will administer a contrast agent into an a peripheral vein (usually in the arm) using a small needle. This contrast agent highlights blood flow in comparison to other organs and structures, and allows the physician to visualize arteries and veins on a CT scan. Compared to a catheter angiogram, this is a much less invasive procedure and is more “patient-friendly,” with a decreased chance of infection or other adverse outcome.

Can anyone have a CT Scan?

s a general rule, anyone can have a CT Scan. We prefer not to scan pregnant women, especially in their first trimester. Decisions as to whether it is prudent to scan a pregnant woman will be made in each case based upon the part of the body being examined, the stage of the pregnancy and the medical necessity of the exam.

What happens during a CT Scan?

You will be asked to lie on a table that slides into a large, circular opening in the doughnut shaped CT scanner. Just prior to the study you will be asked to hold your breath for up to 20 seconds. Cross sectional x-ray pictures are collected as the table moves through the scanner. Detectors in the scanner receive these beams and send signals to a computer. The computer processes these signals and produces a cross-sectional image on a viewing monitor. The electronic digital images are then recorded for the radiologist to interpret.

What is a CT Scan with contrast?

Certain CT Scans are performed with a contrast agent. Your referring doctor and/or the radiologist will decide if contrast is advisable. You may be required to drink a flavored drink containing a barium contrast material which highlights the hollow digestive organ on the images. For some CT scans, you may need intravenous injection of iodinated contrast to help make blood vessels, organs or abnormalities show up better on the scan. Excel Diagnostics & Nuclear Oncology Center uses only non-ionic iodinated contrast agents which are the safest available. Our staff will give you the specific instructions before your exam.

How long does a CT exam take?

Most CT Exams without contrast take about 5 minutes. However, A CT scan may range from 5 minutes to one hour, depending on the type of scan performed. You may ask the technologist before the exam what the expected duration of the exam will be.

How should I prepare for my CT Scan?

Depending on your particular CT scan, you may be given instructions on food and drink consumption the day before and the morning of the exam. Our staff will provide you with those instructions. Feel free to call us if you have any questions.

What happens after the CT Scan?

Our radiologist will review your CT scan and produce a report. The report will be faxed to your referring physician. Your referring physician will discuss the results with you.

What information do I need to provide before the exam?

You will be called and asked to answer questions before your exam regarding your medical history, previous surgeries, and previous radiology exams. You will also need to bring in your medical insurance card for us to bill your insurance company. If you have any questions, call Excel Diagnostics & Nuclear Oncology Center at 713-781-6200.
