When is this exam indicated?

Main applications and indications include cardiac-MR, oncologic MR specific for breast, liver, prostate, pancreas and gastrointestinal system investigations. Orthopedic magnetic resonance provide the most detailed information for joints, muscles and tendons.

How is it performed?

The patient is placed on a bed that moves inside a circular tunnel-like structure (bore) in which the magnets and the gradient and radiofrequency coils are located. The signal obtained is then processed by a computer that provides images of the district examined. Staff will operate the scanner from the next room with whom you can talk during the exam.You will need to be very still and breathe normally -this ensures that the scan images are not blurred. You may be asked to breathe in, breathe out or hold your breath at certain points. During the scan, you will hear clicking or banging noises which are linked to the changing magnetic field as part of the normal exam process.The length of the exam depends on the district under study. If you suffer from claustrophibia (fear of being in a closed space) you must inform the staff prior to the exam.
