Side effects
The administration of contrast medium during an MRI examination can rarely trigger allergic reactions. This can be manifested by itching, rashes, nausea, vomiting, headaches, dizziness, shortness of breath or an allergic shock that can lead to death in the worst case. However, serious or permanent damage is very rare and at the slightest sign of intolerance or allergic reaction, medication can be injected to mitigate the reaction.
Other complications typical of MRI, such as the heating of metal parts in the body or the first appearance of fear of small spaces (claustrophobia), can also occur. But an MRI with claustrophobia is also possible. With older tattoos and permanent make-up, skin irritation or heating of the skin can occur if the dyes contain metal. Extremely rarely, there can be ringing in the ears (tinnitus), which often disappears after the examination, but very rarely can remain. After an MRI examination with or without contrast medium, mild to moderate headaches may occur, which usually subside on their own.
Contraindications
A poor creatinine level, which indicates poor kidney function, is a contraindication for an MRI examination with contrast medium. If there have been allergic reactions to contrast media in the past, the risk of a new reaction should be weighed before use. If an allergy is known, medication can be given as a precautionary measure if the examination has to be performed.In addition, there are contraindications that apply to all MRI examinations, such as metallic foreign bodies (war injury or similar) or pacemakers, as well as fear of narrow spaces (claustrophobia).
Fitness to drive
The ability to drive is not restricted after the administration of a contrast medium. If sedative medication has been given, no vehicles should be driven or dangerous activities performed in the following 24 hours.
MRI with contrast medium knee
In the case of rheumatic, degenerative or chronic diseases of the knee joint, contrast media can supplement the MRI examination, since pre-damaged tissue absorbs contrast media in contrast to healthy tissue. Blood vessels can also be depicted well with contrast medium. In most cases, however, and especially in the case of acute injuries, no contrast medium is administered.
