What are Radionuclide Tests for your Heart?

With heart conditions being such a big killer, it is sensible to let your doctor know if you think that you have a problem with your heart. There are many tests that can be done to look at the health of the heart, and one of the most popular is the ECG test – it is easy and quick, as well as giving a good overall impression of the heart health. It is also used in clinical trials such as these adaptive phase 1 studies by Richmond Pharmacology.


A type of test that you may be asked to have if you have a heart problem is a radionuclide test. There are two main types of this test – they are a CT (computerised tomography) scan and a myocardial perfusion scan. Both of these work using radiation, which is very safe as it is not a large amount.

The CT Test is used if you have pain in your chest, but the doctors are unsure what is causing it. Using this method, they will be able to get a good look at the heart. A substance is injected into a vein before you are then asked to lie in a CT scanner machine. This can diagnose conditions such as an enlarged heart, and heart disease.

The myocardial scan uses a camera to get pictures of what is happening in the body. This is a test that is often used if you have already had a diagnosis of angina but are having chest pains, or to see if you have coronary heart disease.
