Heart scans in Middle Tennessee

Know your risk for heart disease. Specialists at Ascension Saint Thomas provide heart scans that help inform your treatment plan.

A simple heart scan can help you and your doctor better understand your heart health so that you can get the right treatment sooner. A heart scan creates high-resolution images to identify and measure calcium-containing plaque in your arteries. Too much plaque can narrow your arteries and restrict blood flow. If daily tasks or a short walk are more difficult than they used to be, ask about heart screening options.

Calcium buildup in your arteries can be caused by diet, high blood pressure, high cholesterol, diabetes and other pre-existing medical conditions. That’s why our heart care team starts by getting to know you. We listen to understand you and your health concerns. Then, we work together to create a heart care plan that’s right for you.

Who should get a heart scan?

Your age, gender, lifestyle and medical history play a role in your heart health. You may benefit from a heart scan if you:

  • Are a man or woman over age 40
  • Are a smoker or have a history of smoking
  • Have a family history of heart attack at an early age
  • Have diabetes
  • Have high blood pressure
  • Have high cholesterol

*A heart scan is not for everyone. It is not recommended for routine screening of people who do not have symptoms of heart disease and have a low risk of heart attacks. Heart disease risk factors include hypertension, high cholesterol, diabetes, obesity, tobacco use, family history of heart disease. We recommend you work with your doctor on your overall health plan and any risk factors you have.

Schedule your calcium scoring CT

Calcium scoring is a diagnostic screening exam used to detect coronary artery disease (CAD) even in the absence of symptoms. By measuring the amount of calcium buildup in the arteries, this test can identify the presence of CAD and assess its severity if present. To schedule your calcium scoring CT with Premier Radiology, call 615-356-3999.

Advanced imaging for your heart

Care teams at Ascension Saint Thomas provide advanced diagnostics and cardiac imaging, including:

  • Cardiac MRI – advanced imaging technology used to diagnose heart disease.
  • Chest X-ray – used to diagnose chest trauma and heart-lung disease.
  • CT angiography – Advanced CT imaging of the heart that can see both calcified and noncalcified atherosclerotic plaque, used in combination with the HeartFlow® test to diagnose and treat coronary artery disease.
  • Echocardiography – also known as an echo test, uses ultrasound to show heart function. Electrocardiogram (EKG) – records how your heart’s electrical system is working and creates a digital record so your doctor can quickly assess your heart during routine checkups and emergency care.
  • Exercise stress test – records your heart’s activity while you walk on a treadmill.
  • Event monitor – a small recording device that records your heart activity and is used as part of our cardiovascular telehealth monitoring services.
  • HeartFlow® cardiac imaging – creates a 3D image of the heart and arteries to detect blood flow blockages.
  • Holter – a recording device that records the electrical activity of your heart for 24 hours.
  • Myocardial perfusion test – also known as a nuclear stress test, helps your doctor see how your heart muscle works at rest compared to when it’s working during exercise.
  • Transesophageal echocardiogram (TEE) – uses an ultrasound probe placed in your esophagus to create images of your heart.

A doctor’s referral is needed to schedule a heart scan. After your heart scan, your care team sends your results to your heart doctor.
