MRI

IRM, Imagerie La Chaux-de-Fonds

Magnetic resonance imaging (MRI) is an examination that can provide images of all the parts of the body. It uses a magnetic field (magnet). The mechanism is by using many hydrogen nuclei that make up the tissues of the human body ro produce images. An MRI is an examination without irradiation and does not hurt.

Up to 1h15 depending on the body region

  • Pregnancy in progress or desired so that precautions are taken. Please note, this examination is avoided in pregnant women in the first quarter of pregnancy in case the exam is not absolute necessity.
  • Breast feeding: in case of use of contract medium certain precautions must be observed.
  • Risk of allergic reaction to the contrast product.
  • Presence of a pacemaker or any implantable electronic system. It must be ensured that the implanted material is MRI-compatible. If it is not, then the examination is contraindicated. In some cases, the device must be pre-programmed and then reprogrammed after the examination so that it does not malfunction.
  • Presence of any metallic foreign body: ocular implant, certain prostheses, surgical clips, metal shards in the eyes, piercings etc. These could contraindicate the examination.

Except for abdominal MRIs, it is not necessary to be on an empty stomach and the usual medications can be taken.
It is recommended not to put on make-up before a head examination because some eyeshadow, eyeliner, mascara, etc. may contain fine metallic particles.

Claustrophobic patients:

Should you wish, we can administer a light sedation provided you have not already taken another medication. The effect may last beyond the examination. For this reason, it is imperative to be accompanied by someone else for the return in order to avoid a fall or an accident.

  • The examination request from your doctor
  • Your insurance card or accident report

Our medical staff will accompany you throughout your stay in our center.

  • A technician will pick you up in the waiting room then you will go to the changing room, and he will tell you which clothes to take off. You will also have to remove and leave in the cabin any metal parts (jewellery, watch, glasses, hearing and dental prostheses, piercings, etc.). Removing jewelry and piercings already at home reduces the risk of forgetting to do so in our changing room.
  • While on the examination table, the part of your body to be examined will be positioned in the center of the magnet. You will be asked to remain as still as possible so that the images are clear and of good quality. In case of movement, the images become blurred, and the sequence must be restarted. Whatever the duration of the exam, you will always be under surveillance. The medical staff sees and hears you. In the event of a problem, you have a bell in hand which allows you to call us.
  • Having an MRI is a completely painless examination but a bit long and possibly unpleasant due to the repetitive noise inside the device. If necessary, ear protection will be given to you or if the region examined allows it, it is possible to have a headset with music.
  • Some contrast product may need to be injected. The experience is like undergoing a simple blood test.
