FAQ
Unsuitability for scanning
MRI Scans cannot be performed in the following circumstances:
- If you have an implanted pacemaker, defibrillator or simulator
- If you have an electronic/electric implant which cannot be removed
- If you have metal fragments dispersed around your body (depending on the type of examination)
We also try to avoid scanning patients during the first trimester of pregnancy (12-14 weeks)
How to make an appointment
To make an appointment please call 48 42 663 84 66,
Monday to Friday from 8 a.m. to 8 p.m., Saturday and Sunday from 9 a.m. to 3 p.m.
During the registration you will be asked for:
- Name, address and contact number
- Who referred you for the MRI scan and when
- Which part of your body is to be scanned
You will need to bring with you:
- A Doctor’s referral
- An insurance card
- The results of other tests
- Documentation of previous scans
How does the MRI work?
The MRI machine applies an RF (radio frequency) pulse that is specific only to hydrogen. The system directs the pulse towards the area of the body to be examined. The pulse causes the protons in that area to absorb the energy required to make them spin in a different direction. This is the “resonance” part of MRI. The RF pulse forces them (only the one or two extra unmatched protons per million) to spin at a particular frequency, in a particular direction. The specific frequency of resonance is called the Larmour frequency and is calculated based on the particular tissue being imaged and the strength of the main magnetic field. When the RF pulse is turned off, the hydrogen protons begin to slowly return (relatively speaking) to their natural alignment within the magnetic field and release their excess stored energy. When they do this, they give off a signal that the coil now picks up and sends to the computer system. What the system receives is mathematical data that is converted, through the use of a Fourier transformer, into a picture that we can put on film. That is the “imaging” part of MRI.
What to expect at the examination
Before you enter the scanning room, you will be asked to leave all metal and electronic objects in the locker-room. Remember to remove all items from your hair, e.g. hair-clips.
Ladies, please do not use strong make-up as substances in cosmetics can affect the quality of the results.
Certain MRI scans may require an injection of a contrast material, the decision for which is made by either the Doctor who referred you for the scan or the one who is present during the examination. Possible side effects from the injection could be a headache and a feeling of warmth. Very rarely, an allergic reaction may occur.
Next, you enter the scanning room and lie down on a special bed. A coil is set above the part of the body to be scanned. The coil picks up a signal from your body. This signal is used to see the image of your internal organs. When inside the MRI scanner you will hear a strong noise, which is quite normal whilst the scanner is in use. It lasts up to 15 minutes, then disappears and starts again. To feel more comfortable, earphones may be worn.
Whilst inside the scanner, you are connected to the medical team via a hand-held controller, which can be used if you wish to communicate any anxiety.
The scanning room is air-conditioned.
When and how will I receive the results?
The results, in CD format, are available within 3 days. The CD will then be sent to you by post.
