Has your doctor referred you for an MRI scan? It is natural to have questions about the procedure and whether it is safe. Many patients are concerned about radiation exposure or possible side effects from medical imaging.
MRI scans are widely regarded as one of the safest diagnostic imaging methods used in modern radiology. At MBR Health on the Gold Coast, MRI technology allows doctors to examine the body in exceptional detail while avoiding exposure to ionising radiation.
Understanding how MRI works and what to expect can help patients feel more confident before their appointment.
What is MRI and What is it Used For?
Magnetic Resonance Imaging, commonly known as MRI, is an advanced imaging technique used to produce detailed images of the body’s internal structures. Unlike X-rays or CT scans, MRI does not rely on radiation. Instead, it uses strong magnetic fields and radiofrequency waves to generate highly detailed images.
This technology is particularly effective for examining soft tissues in the body, which can be difficult to evaluate with other forms of imaging.
MRI is commonly used in radiology clinics in Australia to assess:
- Brain and neurological conditions
- Spinal injuries and disc problems
- Joint and ligament injuries
- Internal organs such as liver, pancreas, kidneys, breast and prostate
- Whole-body cancer staging and surveillance
- Sport injuries
- Other pain conditions
The high level of detail provided by MRI imaging allows doctors to detect abnormalities that may not be visible using other diagnostic tools.
Why MRI Scans Are Considered Safe?
One of the key advantages of MRI is that the scan does not expose patients to ionising radiation. Imaging techniques such as CT scans and X-rays use radiation to produce images, whereas MRI relies on magnetic energy.
Because of this, MRI scans are often recommended when detailed imaging is required but radiation exposure should be avoided, such as in children, pregnancy, or screening (e.g. whole-body MRI)
MRI has been used in clinical medicine for several decades and is performed millions of times each year around the world. Research and long-term clinical use have consistently demonstrated that MRI is safe when appropriate procedures are followed.
MRI Safety and Medical Implants
Although MRI scans are safe for most people, the strong magnetic field means certain precautions must be taken.
Patients should always inform their radiology provider if they have any implanted medical devices, foreign objects in or on their body, or metal within the body. This may include:
- Pacemakers or implanted defibrillators
- Cochlear implants
- Surgical clips or metal implants
- Metal fragments from previous injuries
- Certain prosthetic devices
Before any MRI scan is performed, patients complete a safety questionnaire. This allows the radiology team to confirm that the scan is suitable and safe for the individual. Prior to entering the scanner room, the MRI team will confirm MRI safety again with the individual.
MRI During Pregnancy
MRI scans may sometimes be recommended during pregnancy when important diagnostic information is needed. Because MRI does not involve radiation, it can be an appropriate imaging option in some circumstances.
However, the decision to perform an MRI during pregnancy is made carefully by the referring doctor and radiologist. Each situation is assessed individually to ensure the scan is medically necessary.
What to Expect During an MRI Scan
Many patients feel uncertain about what happens during an MRI scan. In reality, the procedure is straightforward and non-invasive.
During the scan, the patient lies on a padded table that moves into the MRI scanner. The machine captures detailed images while producing rhythmic tapping or knocking sounds. Ear protection is typically provided to ensure comfort. Some clinics also offer an MRI cinema experience, meaning you can watch TV shows or movies during your scan for a more comfortable experience.
Depending on the area being examined, most MRI scans take between 30 and 60 minutes. Remaining still during the scan helps ensure the images are clear and accurate.
Some scans may involve the use of contrast dye to highlight certain structures or blood vessels. If contrast is required, the radiology team will inform you.
Is MRI Contrast Safe?
In some cases, an MRI scan may involve the use of a contrast agent to improve image clarity. MRI contrast typically contains gadolinium and is injected into a vein during the scan to help highlight blood vessels, inflammation, or abnormal tissue.
For most patients, MRI contrast is considered very safe and is used routinely in radiology when additional detail is needed for accurate diagnosis. Side effects are uncommon and usually mild, and the contrast material is naturally filtered from the body by the kidneys after the scan. Before administering contrast, the radiology team will review your medical history and kidney function to ensure the procedure is appropriate for you. You are welcome to ask any questions you may have about whether or not IV contrast is right for you.

Frequently Asked Questions
Below are some commonly asked questions. For a full list, visit our frequently asked questions page.
Does an MRI scan use radiation?
No. MRI scans do not use ionising radiation. Instead, MRI technology uses strong magnetic fields and radiofrequency waves to create detailed images of the body. This makes MRI an important diagnostic tool in radiology when doctors need high-quality images without exposing patients to radiation.
Is an MRI scan painful?
MRI scans are non-invasive and painless. Patients lie on a padded table that moves into the MRI scanner while images are taken. The machine produces rhythmic tapping or knocking sounds during the scan, but ear protection is usually provided. The most important requirement is remaining still so the images are clear.
Can I have an MRI if I have metal in my body?
Possibly, but it depends on the type of metal or medical device. Because MRI uses strong magnetic fields, patients must inform the radiology team about any implants, surgical clips, pacemakers, or metal fragments in the body. Many modern implants are MRI-compatible, but the radiology team will review your medical history and ensure the scan can be performed safely.
Do I need a referral for an MRI scan?
In most cases, an MRI scan requires a referral from a doctor, specialist, or other qualified healthcare provider. The referral outlines the clinical reason for the scan and helps the radiologist focus on the area being investigated. If you are unsure whether you need a referral for a Gold Coast MRI, the team at MBR Health can advise you and help guide the booking process.
Is an MRI scan at MBR Health covered by Medicare?
No. MRI scans are not bulk billed at MBR Health. Patients will generally have an out-of-pocket cost for their MRI scan. For more information on how Medicare applies rebates to MRI scans, visit our blog “MRI Medicare Rebates Explained”.
