Magnetic Resonance Imaging (MRI)
MRI is a cross-sectional imaging procedure based on a strong magnetic field. Since the examination is not associated with radiation exposure, it is used particularly frequently in pediatric radiology.

Examination
MRI examinations are suitable for a wide range of questions concerning the whole body. Depending on the question, the application of intravenous contrast medium may be necessary. For the assessment of the gastrointestinal tract, a so-called MRI-sellink, your child will be given a sugar solution to drink before the examination in order to fill the intestinal loops and thus to be able to assess them better.
Prior to the examination, you will be informed about the indication, the procedure and the risks of the examination.
MRI examinations last between 15 - 60 minutes, depending on the question. Since your child must be positioned as calmly as possible during the entire procedure, the examination may be performed under sedation or anesthesia, depending on age and previous illnesses. In this case, you will receive a separate preparatory consultation by a physician from the anesthesia department.
In our pediatric MRI, patients can listen to radio or music during the examination if they wish. Films can also be watched during some examinations. In most cases, the duration appears shorter and it makes it easier for the child to lie still.
If necessary, a parent or an accompanying person can be present in the examination room. Pregnant accompanying persons or persons with pacemakers or other implants that can be influenced by a magnetic field are excluded from this.
Preparation
- Before the MRI examination, all metallic parts, i.e. jewelry, hair clips, wristwatches, etc., must be taken off. It is best if your child wears comfortable clothing without metallic zippers, buttons, rivets, sequins or glittering prints.
- If the face is to be examined, any braces may need to be removed. If you have fixed braces, please contact us before the examination. So-called retainers (small wires on the back of the teeth) are usually not bothersome.
- If an intravenous contrast agent is used, venous access is placed in advance, usually in the crook of the arm.
- In the case of an MRI sellink (also called hydro-MRI), the child should be fed a low-fat, low-fiber diet starting the day before and should be fasting for the exam.
- In all other cases, if sedation or anesthesia has not been arranged, your child does not need to come on an empty stomach.
