What is an MRI scan?

 

An MRI (Magnetic Resonance Imaging) scan is a safe and non-invasive imaging test that uses strong magnets and radio waves to produce detailed images of the inside of your body.

These images are converted into grayscale, which allows doctors to detect differences between normal and abnormal tissue. Compared to other imaging devices, MRI scans provide an exceptional level of soft tissue detail.

MRI scans are commonly used to examine the brain, spine, joints, muscles, and internal organs, helping your doctor diagnose and monitor a wide range of conditions.

What are MRI scans used for?

An MRI scan is particularly useful for assessing the head and spine, abdomen and pelvis, breast and for joint and musculoskeletal problems.

An MRI scan requires specialised equipment and expertise, and allows evaluation of body structures that may not be visible with other imaging methods.

The appointment generally takes between 30-60 minutes.

A trained, experienced staff member will discuss the procedure with you. This is a good opportunity to ask any question you may have.

You will be asked to change into a gown and remove all metallic objects such as jewellery, dentures, hearing aids, etc.

Your Examination

If needed, you will have an intravenous line inserted. Our staff will position you on a bed that will gently move through the scanner, stopping to scan relevant areas. You will be asked to remain still throughout each of the 4-5 separate scans for up to twenty minutes. If you have difficulty lying flat, or are uncomfortable in confined spaces, the MRI staff will assist and make you more comfortable.

The Medical Radiation Technologist (MRT) or Radiographer will talk to you via a two-way intercom during the scan and let you know what is happening throughout. You can talk to the MRT at any time, even during the scan if you need to. If you have any questions, please don’t hesitate to ask. The MRI machine makes a loud tapping noise while scanning (from the MRI coil movement) however you will be able to listen to music during the scan. 

Post Examination

You will be asked to change back into your clothes and your items will be returned to you. You will be monitored for 10 minutes. You may eat or drink after your scan. There are no known side effects from the magnetic field.
