What is Magnetic Resonance Imaging (MRI)?
Magnetic Resonance Imaging or MRI is a new way to visualize the inside of the body. This new technology has no harmful biological effect.
What Is special about Magnetic Resonance?
This new Imaging technique does not use ionizing radiation like X-Rays or CT. It is painless, has no side effects and in 90% of the cases does not require injection of contrast agents. This technique gives additional informations to other diagnostic methods.
How does it work?
In the scanner you will be exposed to two natural phenomena: a magnetic field and Radio waves. Water molecules within your body will react to those two forces, by aligning themselves with the magnetic field as well as reemitting radio signals matching those emitted by the system. These signals are then processed into images with the use of a computer.
What should I do during the exam?
The only things we will ask you to do is to stay still and relax as we proceed with the examination.
Will I feel Something?
Not at all but you will hear lots of knocking noises when we do the images.

Must I be alone?
The design of the equipment is such that it is not possible for someone to be by your side. In extreme conditions someone may be in the examination room for reassurance.
After the exam you will be able to attend normal activities without any problems.
What happens during the exam?
During the test you will be required to lie very still on a bed inside a large scanner. During the scanning procedure you will hear knocking sounds. With MR there is no radiation or radioactive material. If you are on medication, please take it as scheduled.
Why must I keep my appointment?
Due to the length of the procedure only a small number of patients can be examined each day. We make every effort to stay on schedule, but please bring a book or craft in case you must wait. We also ask that you arrive 30 minutes earlier than your appointment time.
Whom should I call if I have any concerns?
If you have questions, please call your doctor who requested the exam.
