About Myocardial Perfusion Scan (Exercise)

A Myocardial Perfusion Scan (Exercise) is a nuclear medicine cardiac imaging examination used to assess blood flow to the heart muscle following physical exercise. It typically uses a prescribed radioactive tracer and a gamma camera to produce images showing the distribution of tracer uptake in the myocardium.

The examination is performed according to a clinical protocol determined by the referring cardiologist and nuclear medicine team. The imaging approach and any additional scans depend on the clinical indication.

What Does an Exercise Myocardial Perfusion Scan Evaluate?

The scan evaluates the distribution of radiotracer uptake in the heart muscle following exercise stress. It may help identify areas with reduced tracer uptake that require further assessment for possible myocardial perfusion abnormalities.

The findings are interpreted alongside symptoms, medical history, electrocardiography and other cardiac investigations.

Why Is a Myocardial Perfusion Scan Recommended?

A cardiologist may recommend an exercise myocardial perfusion scan when evaluating selected patients with suspected or known coronary artery disease or symptoms that require assessment of blood flow to the heart muscle during stress.

The results may contribute to further cardiac evaluation and treatment planning. The suitability of the examination depends on the patient's health, symptoms and clinical assessment.

How Is a Myocardial Perfusion Scan (Exercise) Performed?

A prescribed radiotracer is administered according to the examination protocol. The patient performs supervised physical activity, commonly on a treadmill, while the clinical team monitors the patient's response to exercise.

The radiotracer is administered at the appropriate stage of the stress protocol. A gamma camera then acquires images of the heart to assess tracer distribution in the myocardium.

Heart rate, blood pressure and electrocardiographic changes may be monitored during the exercise component. The exact procedure and imaging schedule depend on the prescribed protocol.

Preparation for Myocardial Perfusion Scan (Exercise)

Preparation requirements depend on the imaging protocol and the patient's medical condition. Follow the instructions provided by the nuclear medicine team and referring cardiologist.

• Follow instructions regarding fasting, food and fluid intake.
• Avoid caffeine-containing products if instructed by the clinical team.
• Inform the team about current medications and existing medical conditions.
• Wear comfortable clothing and appropriate footwear for exercise testing.
• Bring previous cardiac reports and relevant investigation results.
• Inform the team about pregnancy or possible pregnancy and breastfeeding, where applicable.

Do not stop prescribed heart medications unless specifically instructed by your treating doctor.

Benefits of Exercise Myocardial Perfusion Imaging

Exercise myocardial perfusion imaging provides functional information about blood flow to the heart muscle following physical activity. It may help doctors investigate possible perfusion abnormalities in appropriately selected patients.

The findings are considered alongside symptoms, exercise response and other cardiac investigations. The scan does not replace a complete cardiovascular assessment.

Understanding the Myocardial Perfusion Scan Report

The report may describe radiotracer uptake in different regions of the heart and identify areas that require further evaluation. The significance of the findings depends on the imaging pattern, image quality and clinical context.

A qualified nuclear medicine physician interprets the images. The treating cardiologist explains the findings and their implications for further assessment or management.

Frequently Asked Questions

What is a Myocardial Perfusion Scan (Exercise)?

It is a nuclear medicine cardiac imaging examination used to evaluate blood flow to the heart muscle following supervised physical exercise.

Why is an exercise myocardial perfusion scan performed?

It may be recommended to assess myocardial blood flow in selected patients with suspected or known coronary artery disease.

Does the scan use a gamma camera?

Yes. The examination typically uses a gamma camera to detect radiation from the administered radiotracer and produce images of the heart muscle.

Does the scan involve radiation?

Yes. The examination uses a radioactive tracer and involves exposure to ionising radiation. The nuclear medicine team selects the appropriate protocol for the clinical indication.

Can I eat or drink before the scan?

Preparation requirements vary. Follow the centre's instructions regarding fasting, caffeine, fluids and medication before the examination.

How long does an exercise myocardial perfusion scan take?

The duration depends on the radiotracer, stress protocol and imaging schedule. Contact the centre for timing information specific to your examination.

Can everyone undergo exercise myocardial perfusion imaging?

No. Suitability depends on the patient's health, ability to exercise and clinical indication. The treating cardiologist and supervising team determine the appropriate testing method.
