Cardiac MRI

Why is it done?

A cardiac MRI (Magnetic Resonance Imaging) is a non-invasive test that takes very detailed pictures of the heart muscle and valves.


This test has the advantages of being noninvasive. It is a safe test producing a magentic field without the use of radiation.


The scan takes approximately 30-90 minutes to perform depending on the images being taken. It is relatively common for patients to become claustrophobic in the scanner (roughly one in six) beause of the 'tunnel' and noise the machine makes. If you are likely to become claustrophobic during the test remember to mention this to you doctor - who may be able to prescribe you something to relax you on the day.
