Myocardial Perfusion Scan (MIBI)

A Myocardial Perfusion scan, also known as MIBI, MPS or Thallium scan, evaluates coronary artery disease by assessing the blood flow to the heart muscle both at rest and at stress.

The scan involves the use of an injected radioisotope and a dedicated SPECT/CT camera. After the radioisotope has been intravenously injected, the camera is used to produce images of the heart.

These images show both the condition and function of the heart during stress testing (both at rest and stress).

What conditions can be diagnosed by a Myocardial Perfusion Scan?

Myocardial Perfusion scan can be used to:

  • Evaluate blood flow to the heart muscle
  • Check for heart disease
  • Determine whether there is any damage to the heart

Clinical stress testing is usually performed on patients with known or suspected coronary artery disease. While every effort will be made to minimise the risks of the procedure, there is a small risk of complication.

You may be asked to cease certain medications prior to the test.

Caffeine needs to be ceased 24 hours prior to your appointment (this includes, but not limited to, chocolate, tea, coffee, cola, soft drinks, etc).

Fast 4 hours prior to test then water only.
