The MRI examination device makes very loud and various knocking noises. To reduce the volume of these noises, the patient may receive headphone when set up, it can also communicate with the responsible staff at the same time.

The patient is provided with the venous access during the MRI-Sellink examination Medication administered.

This is to ensure that sharp images are created of the intestinal sections, which then enable a very good assessment.
In the meantime, a Contrast media passed into the veins, which after some time has also spread in the intestinal mucosa. Contrast media offer the opportunity to better differentiate changed tissue such as that of a tumor from healthy tissue.
In addition, the Structures such as vessels and tissue thereby in the Sellink MRI examination more visible because the cells of different tissues absorb the contrast agent to different degrees. There are several advantages to this method.

Duration of the Sellink MRI

The examination can also reveal malformations, fistulas, disorders of bowel rotation during development or stenoses.

Is there any suspicion tumor Having developed in the area of ​​the small intestine, the MRI scan can also be a very good diagnostic tool.
The images can be used to detect tumors Contrast media can be judged particularly well in terms of their location and size.
Furthermore, the investigation becomes Clarification of unclear diarrhea, Bleeding and Intolerance reactions to food used.
However, the examination can also be carried out after surgical interventions such as the removal of individual sections of the small intestine. In this way, on the one hand, it is possible to check whether the seams are tight and, on the other hand, the position of the remaining sections of the small intestine can be assessed.


The Sellink MRI examination is contraindicated in patients with a Pacemaker, a built-in Cardio defibrillator, firmly implanted Neurostimulator or one Insulin pump or Dentures with magnetic brackets.
Implanted devices are supported by the MRI according to Sellink massively tightened and damaged and, accordingly, can lead to serious complications.
The doctor should also have a known one allergy or Intolerance to the contrast agent be informed.

The examination should still not be carried out if a pregnancy in the first trimester (1st third) consists. `
So far, damage to the fetus has not yet been proven with certainty, but an examination should only be carried out under strict indication and in exceptional cases.
