Cardiac Imaging

Noosa Radiology provides a wide range of Cardiac imaging services daily, including CT Coronary Angiography, CT Coronary Calcium Scoring, Stress Echocardiography, Echocardiography, Myocardial Perfusion, Exercise Stress Test and Holter Monitoring.

Preparing for your examination

Please be aware that all Cardiac Imaging requires an appointment. Please call us to arrange a time.

What to bring:

  • A referral from your GP or specialist to have the examination
  • Medicare card
  • Pension/concession card
  • Previous films from other clinics relating to the area being scanned with us

Please tell us if you are pregnant or breastfeeding.

You may be required to have a consultation prior to the examination. Please contact Noosa Radiology staff to organise an appointment.

Some procedures require preparation including fasting and being well hydrated. You should continue taking all prescribed medications as usual.

Reasons for Cardiac Imaging

CT Coronary Angiography

Every day adults with no symptoms of heart disease fall victim to the "silent killer". Each year more than 100,000 people will die of heart attacks before they reach a hospital. For both men and women, heart disease claims more lives than the next six causes of death combined. Because symptoms such as chest pain do not usually occur until the very late stages of disease, many individuals are not aware that a problem or condition exists until it is too late.

With the latest CT technology at Noosa Radiology, we now have the ability to see crisp, clean video of the heart and coronary arteries. Your GP can request a CT scan of the heart and chest that will give you a measure of your heart health before any symptoms such as chest pain or shortness of breath occur. Consider it a one-stop heart check-up with an analysis of the coronary arteries, valves and myocardial mass. Prior to 64 detector technology, assessment of the coronary arteries was only available by inserting a catheter into a leg artery, which generally involves day admission to hospital. This revolutionary technology was recently featured in Time Magazine as one of the most significant advances in medical imaging technology.

CT Coronary Calcium Scoring

Coronary Calcium Score is an alternative to CT Coronary Angiography (CTCA) to screen for coronary artery disease. A limited CT scan is performed to measure calcific atherosclerotic plaque. This test has been available for over 20 years and is useful in risk stratification.

Stress Echocardiography

Exercise Stress Echocardiogram (stress echo) is a test that determines how well your heart & blood vessels are working before and after exercise. A Cardiologist uses both ultrasound images as well as the electrocardiogram (ECG) to provide a comprehensive assessment of your heart function. You will be asked to exercise on a treadmill. When your heart rate reaches peak levels, an ultrasound is taken to determine whether your heart muscles are getting enough blood & oxygen while you exercise. Stress Echo can help diagnose a range of heart problems as well as provide a treatment plan for cardiac rehabilitation.

Echocardiography

This is an ultrasound of the heart and is performed by a qualified technician using a dedicated ultrasound probe and software. This examination is predominantly used to assess function of the cardiac chambers and valves. The examination is performed by an echocardiographer. It may take up to 45 minutes and requires changing into a gown.

Myocardial Perfusion

Nucelar Myocardial Perfusion studies are a non-invasive and reproducible procedure to demonstrate blood flow to the heart, or myocardium. A tracer is administered intravenously at rest and after stress. Patient's can be stressed using a treadmill or by administration of a pharmaceutical. This gives functional information of areas of the heart which receive reduced blood flow at stress, indicating a significant narrowing to one or more of the coronary arteries.

Noosa Radiology has the latest SPECT/CT Gamma Camera from Siemens. This technology results in up to 25% increased accuracy in myocardial perfusion studies with reduced patient dose. We are the only centre on the Sunshine Coast which can fuse imaging from CT Coronary Angiography with Myocardial Perfusion studies to provide an anatomical vascular map of coronary narrowing.

Exercise Stress Test

An exercise stress test is used to measure the effect of exercise on the heart. This test involves you walking slowly and/or jogging on a treadmill so the activity of your heart can be measured. One of our doctors are in the room with you at all times. Please call Noosa Radiology for more information or to book an appointment.

Holter Monitoring

A holter monitor is a small battery operated portable device that measures and records your hearts activity continuously for 24 hours. Your GP or specialist may refer you for a holter monitor to see if you have a slow, fast or irregular heartbeat. This monitor has no risks and isn't painful to wear. To undergo a holter monitor test you will need to make an appointment with Noosa Radiology. Over the next 24 hours, it is recommended that you proceed with your usual daily activities to ensure the monitor captures an accurate reading of your heart rate and rhythm. You will be given a time to come back to Noosa Radiology to have the holter removed. A report will be sent to your referring GP or specialist the following day.
