Nuclear Tests – ‘MUGA’ and ‘MIBI’

A MUGA is a common test used to determine the function of your heart. This test consists of a special scan of your heart using a radio-isotope solution that is injected into a vein.

A MIBI also uses a different radio-isotope to take pictures of your heart muscle at rest and during exercise or stress to determine if you have narrow or blocked arteries in your heart that could cause chest pain or weak heart muscle.

What the test shows:

The blood flow through the heart

How well the heart muscle is supplied with blood

How well the heart's chambers are working

How badly the heart has been damaged by a heart attack
