Nuclear Medicine & Echocardiography

Queensland Nuclear Imaging is a independent imaging service specialising in a full range of nuclear medicine diagnostic imaging.

We specialise in cardiac stress testing with myocardial perfusion imaging as well as echocardiography (cardiac ultrasound).

Experienced & Dedicated Team

We are staffed by an experienced team of nuclear medicine specialists and cardiologists.

Cardiac stress tests are personally supervised by consultant physicians. All procedures are conducted within the safety of a tertiary cardiac hospital - the Prince Charles Hospital.

All Tests Bulk-Billed

All tests are bulk-billed, with no out of pocket expenses for the patient.

All reports are available the same day.

What is Nuclear Medicine?

Nuclear medicine imaging is unique, because it provides doctors with information about both structure and function of organs.

It is a way to gather medical information that would otherwise be unavailable, require surgery or necessitate more expensive diagnostic tests.

Nuclear medicine imaging procedures often identify abnormalities very early in the progress of a disease, sometimes long before many medical problems are apparent with other diagnostic tests.


What are Radiopharmaceuticals?

Nuclear medicine uses very small amounts of radioactive materials (radiopharmaceuticals) to diagnose and treat disease.

In imaging, the radiopharmaceuticals are detected by special types of cameras that work with computers to provide very precise pictures about the area of the body being imaged.

In treatment, the radiopharmaceuticals go directly to the organ being treated.


Is it safe?

The amount of radiation in a typical nuclear imaging procedure is comparable with that received during a diagnostic x-ray.

Depending on the type of nuclear medicine exam you are undergoing, the radiotracer is either injected into a vein, swallowed or inhaled as a gas and eventually accumulates in the organ or area of your body being examined. There it gives off energy in the form of gamma rays, which are detected by the gamma camera.

Information for Referrers

Queensland Nuclear Imaging (QNI) is an independent nuclear medicine and echocardiography service collocated in the grounds of the Holy Spirit Northside and Prince Charles Hospital campus.

QNI provides a comprehensive nuclear medicine imaging service specialising in cardiac stress testing with myocardial perfusion imaging.


Patients are bulk billed for QNI tests.

All Nuclear medicine studies and Echocardiography will be entirely cost neutral for the patient, with no out of pocket expenses.


Same-day reports

Reports will be available same day via download with Medical-Objects software or via fax.

In the case of significant abnormal results, the supervising physician will telephone the referring doctor.


Patient Services

We will advise the patient regarding any preparation which may be needed but this is also detailed on the back of the A4 referral and within the Information for Patients section of this web page.

We are available for phone consultations at any time on (07) 3139 4010.


Referral Form

A referral may be faxed to us on (07) 3139 4577 or ask the patient to contact our receptionist on (07) 3139 4010.

Cardiac stress testing at QNI

Nuclear myocardial perfusion stress imaging (MPS) involves the use of radiotracers to generate scintigraphic images of the myocardium. It is the best validated and most standardised of all cardiac imaging modalities, demonstrating regional perfusion, ventricular wall motion and accurately calculating left ventricular ejection fraction.

Stress testing is either performed using treadmill exercise or pharmacological stress with Dobutamine or Dipyridamole in those who cannot exercise. There are very few contraindications. Stress testing is conducted in the safety of a tertiary cardiac hospital and is conducted by experienced consultant physicians.

Applications include:

  • triaging of chest pain, including patients who are unable to adequately exercise.
  • patients with abnormal resting ECG where interpretation of exercise ECG is impossible(eg, baseline ST segment changes, LBBB)
  • when standard stress ECG is equivocal or may be falsely positive eg middle-aged women.
  • Cardiac event prediction in asymptomatic patients eg before major surgery, and where silent myocardial ischaemia is likely eg diabetics.
  • patients with known coronary artery disease eg to assess perfusion post angioplasty, or to determine if a stenosis is functionally significant.

Sensitivity and specificity for prediction of significant coronary artery disease is 80-85%, similar to stress echocardiography.

Our Location



The Private Practice Clinic is situated in the Administration Building which is the second building on your right (¾ of the way up the hill) as you head towards the Prince Charles Hospital campus from Rode Road. It is between Holy Spirit Hospital and Brisbane Emergency.
There is parking available in the multi-storey car park (METRO parking) which is on the left-hand side of the road almost opposite our building. This is a private car park and charges may apply. When you exit the car park walk up the 4 steps and then veer to your right following the pedestrian crossing across.
There is signage on the fencing marked Private Practice Clinic and Queensland Nuclear Imaging (QNI). Once you have crossed the crossing you will see a green sign saying Holy Spirit Hospital, beside this sign is a ramp going down (where cars are parked) to the Administration Building. We are on the ground floor of this building.
