WHAT IS MRI AND HOW DOES IT WORK?

Magnetic Resonance Imaging (MRI) scan is a specialised tool in medical diagnostics that assists doctors in making diagnoses and determining therapies. It is currently the most accurate radiological technique for diagnosing issues with joints and the nervous system. MRI combines the advantages of computed tomography (CT) and ultrasound scans, allowing for multidimensional imaging. It is also very effective in visualising blood vessels, including 3D reconstructions, providing a wealth of information without the need for invasive procedures. MRI can be used to examine the brain, abdominal organs, spine, bones, joints, and the area around the thoracic vessels.

MRI does not use X-rays for imaging; instead, it uses a magnetic field, so patients are not exposed to harmful radiation. The scan is based on the altered behaviour of the body's fluid spaces (about two-thirds of the human body is water) in a magnetic field, using the body's natural magnetic factors, with the help of a powerful external magnet. Changes in the water content of tissues and cells due to lesions make them visible.

MRI is suitable for diagnosing various conditions, including injuries (sprains, strains, tears, fractures), inflammations, neurological diseases (strokes, cerebral palsy, dizziness, headaches, multiple sclerosis, epilepsy, etc.), spinal diseases (scoliosis, herniated discs, osteoporosis, etc.), metabolic disorders, vascular diseases, developmental disorders, and tumours and their metastases.

The test is painless, harmless, and has no side effects. It can be repeated as often as necessary and is safe even for children. However, patients with pacemakers, magnetisable implants, or metallic materials cannot undergo an MRI.

WHAT ARE THE IMPLANTED METAL OBJECTS THAT CAN BE SAFELY USED FOR AN MRI TEST?

The possibility of undergoing an MRI scan depends on the specific type of implanted object.

A heart rhythm regulator (pacemaker) precludes the possibility of undergoing an MRI scan.

If a bullet, shot, or metal fragment is located in the face, especially around the eye, an MRI scan cannot be performed.

For objects such as brain or aneurysm clips, heart valves, or stents, only patients who provide written confirmation of MRI compatibility can be examined.

Artificial eyes, hearing aids, joint prostheses, artificial limbs, orthopaedic metal materials (screws, plates, nails, wires), as well as other metal objects or materials (such as dental fillings, bridges, crowns, piercings, braces, and spirals) can be tested during the examination.

 

 

CAN AN MRI TEST BE DONE DURING PREGNANCY?

Yes, but be aware that MRI scans are not recommended in the first trimester of pregnancy. The earliest time for an MRI scan is from the beginning of the fourth month, after the 13th week of pregnancy.

 

WHY DO I HAVE TO SIGN A CONSENT FORM?

It's important to sign a consent form before an MRI scan for a few reasons. The MRI machine uses a strong magnetic field, so metal objects can't be brought into the scan area because they can be attracted to the machine and cause injury. Even small metal objects like buttons or clasps can be dangerous, so it's best to wear clothing without metallic objects.

Additionally, a contrast material is sometimes used during the MRI to make the images more clear. While very rare, some people may have allergic reactions to the contrast material. However, the contrast material used for MRI scans is less likely to cause allergies than the one used for CT scans. The contrast material used in MRI scans goes through strict pharmaceutical testing and is considered safe.

HOW IS THE EXAMINATION CARRIED OUT?

The examination is conducted by specialised, experienced professionals in an examination room with a strong magnetic field. Before entering the room, the patient needs to ensure that there are no metal objects on or in their body (e.g., clothing, jewellery, glasses, pacemaker) as these objects can move, heat up, and malfunction in the magnetic field. All metal objects should be left in the changing room.

Once in the examination room, the patient will lie down on the examination table. A magnetic coil will be placed around the body part examined. If the patient feels scared or anxious, they can communicate with the radiographer via a microphone, who can see and hear them through a special glass window. The patient must remain still and breathe evenly during the test, which may last 10-30 minutes. The patient will be provided with headphones or earplugs to help them cope with the clicking noise during the MRI scan.

In some cases, the test may require the use of intravenous contrast material. This contrast agent does not contain iodine and is different from substances used in X-ray examinations. Allergic reactions to this substance are rare, and it helps enhance the contrast of the images.

DO I NEED A REFERRAL FOR PAID (NON-OEP FUNDED) SCANS?

Tests are not covered by social security, so a referral from a general practitioner or specialist is not required. However, we advise our clients to consult their general practitioner or specialist before having an MRI scan if they have any symptoms of illness, injury, or change in health. Please note that an MRI can also be used to confirm a medical condition.

WHEN WILL I GET THE RESULTS OF THE TEST?

We will send the scanned images to the email address you provide. They will be available for download for 30 days and can be downloaded three times to your computer. Our radiologist will provide a written opinion within 3-4 working days. The receptionist at the surgery will inform you about the expected date and time of the result release and the delivery method.

If the patient is not the intended recipient, a report can only be issued with a power of attorney (POA)  signed by two witnesses (name, address) or a POA countersigned by a lawyer. You can request a POA form at the reception desk.

CAN I TALK TO THE DOCTOR BEFORE OR AFTER THE TEST?

Patients have the right to receive personalized information about the test in a way they can understand, either orally or in writing, and to ask the doctor any questions they may have before or after the examination. Any technical questions should be directed to the receptionist or operators first. If the question is medical in nature, the doctor will answer it. Please note that our practice is a diagnostic institute and we are unable to provide comprehensive information about our patients' conditions, treatment methods, or how the test results may affect their treatment. Our doctors can only provide information about the specific MRI examination and matters related to it. Further treatment will be discussed with the specialist at the referring institution.

CAN I HAVE A HEALTH INSURANCE-FUNDED TEST?

An invoice will be issued in the name and address of your health insurance company, with your details (name, address, member ID). You can verify this with your health insurance provider.

CAN I GET AN EXTRA COPY OF THE FINDINGS OR A CD COPY AFTERWARDS?
