The nuclear magnetic or magnetic resonance imaging (MRI) is a modern examination method which provides highly detailed tomographic images of the human body without using X-rays.
For the examination, the patient will be surrounded by a strong magnetic field inside a tube (several times the Earth's gravity).
A very powerful computer system provides layers of images at different levels.
Cross-sectional views of all body regions can be created using this procedure. This includes, for example brain, spinal cord, spine and internal organs as well as soft tissues and joints. Even blood vessels can be represented using this method.
PreparationAs a strong magnetic field is present both in the examination room and in the device, metallic objects, such as keys, coins, lighters, watches, glasses, jewellery, belts or magnetically sensitive things such as credit and debit cards must be stored in the locker room prior to the examination.
During the scan, which is accompanied by technically unavoidable knocking sounds, you should remain quiet and relaxed, as any movement causes defects the image scanning and extends the length of the examination.
Depending on the issue, the time in the machine can be up to 45 minutes.
Reports on findings or images of past investigations (such as previous MRIs, x-rays, ultrasound, or computer tomography) may be useful for evaluation and comparison and should be brought along if possible.
Reasons not to carry out an examinationExaminations are currently not suitable for patients with a pacemaker. In case of pregnancy and if metal objects are present in the body such as prosthetic joints, metal splints or clips after operations, it must be decided on a case-by-case basis whether an MRI is possible and sensible.
