Coronary CTA & Grossman Imaging Centers

In 2006 Grossman Imaging Centers opened their newest facility featuring the most advanced non-invasive CT exam for detecting coronary artery disease, their GE LightSpeed VCT 64 Slice CT Scanner. With this groundbreaking technology which provides unprecedented image quality, we are able to capture images of the coronary arteries in fewer than five heart beats.

What does this mean to you as a patient?

Coronary CT Angiography can provide the earliest possible evidence of coronary artery disease. Most heart attacks and sudden death occurs from plaques that are not significant enough to cause symptoms and abnormalities on other cardiac testing. Many patients who present with their first heart attack have no risk factors at all. Early detection and treatment of cardiovascular disease may help prevent loss of function. The GE 64 Slice CT Scanner completes a specialized CT scan in fewer than five heartbeats and uses highly advanced computers to produce 3-D 360-degree images of the coronary arteries, the place where heart attacks originate.

What does this mean to your doctor?

Coronary CT Angiography gives accurate information about coronary arteries, including narrowing and the degree of plaque. Coronary CTA is the only non-invasive diagnostic test that detects calcified, and more importantly, non-calcified (soft or vulnerable) plaques which are more likely to cause heart attacks and sudden death. This exam can detect heart artery plaque before it shows up on an EKG, stress test, or even a heart catheterization. Stress testing usually only detects plaque that is functionally severe. This gives your doctor a better assessment of your risk and allows for an earlier and better treatment plan.

Early Detection Before Loss of Function

Do you know your risks for heart disease?

  • High Blood Pressure
  • High Cholesterol
  • High Stress Environment
  • Smoking
  • Family History of Heart Disease
  • Diabetes
  • Being Overweight
  • Inactive Lifestyle

Heart disease affects both men and women. Although men are more susceptible at an earlier age, a woman’s risk of having a heart attack rises markedly after menopause.

What is a CT scan? (CAT scan)

CT is an abbreviation for a diagnostic procedure called Computed Tomography. This valuable exam combines X-rays and sophisticated computers to generate detailed anatomical images. A CT scan gives physicians a non-invasive way to see inside your body and the advantage of CT is its ability to rapidly acquire two-dimensional pictures of your anatomy.

Is it Safe?

CT is a safe and effective diagnostic procedure. Like many other imaging technologies, CT has been cleared by the U.S. Food and Drug Administration. In addition, the GE LightSpeed VCT system has been designed with dose reduction features that minimize your exposure to radiation.

What is a Calcium Score and will you be performing one?

With the use of a CT this test measures the amount of calcium deposited in your coronary arteries. The results are expressed as a calcium score. This score gives a risk factor of the severity of coronary disease, an indication that you might be at an increased risk for a heart attack. If your calcium score is too high, the CT Angiography may not be performed, as the results may be less effective. Determining the extent of cardiac risk requires your doctor to interpret your calcium score in combination with other test and risk factors. It is important to remember that this assessment is only intended as an estimate of your risk of heart disease or a heart attack. Talk to your doctor regarding the results of your CT Angiography and Calcium Score. A complete report will be provided to your physician by our Radiologist.

What is a beta-blocker?

Beta blockers decrease the force and rate of heart contractions. It is necessary for your Coronary CTA exam to have your heart rate as close to 60 as possible. If you are currently taking a beta blocker or high blood pressure medication YOU MUST check with your doctor prior to taking the beta-blocker that is provided to you for this study.

This exciting technology is a new technique giving a 3D, non invasive, 360° examination of the coronary arteries. CTA not only allows the assessment of the arterial lumen (or the channel within the artery) but is also used to visualize the walls of the coronary arteries, demonstrating the presence of calcified and soft plaque or critical narrowing which could lead to a myocardial infarction (heart attack).

While the findings of Coronary Artery Calcification Screening (CACS) are limited to calcified atherosclerotic plaque, Coronary CTA (CCTA) is a more comprehensive exam whose findings are comparable to invasive coronary angiography. Click here to see images of the Lightspeed VCT 64 Detector

“In 2000, 1,500,000 coronary angiography procedures were performed in the US, 50% which were diagnostic. Of those 50% required no additional procedure” – ACC/AHA Guidelines for Coronary Angiography, 1999, Scanlon and Faxon

“The rupture of a plaque will be the cause of death of about half of all of us in the United States.” - Dr. Steven Nissen, Cleveland Clinic
