Examinations | MRI-scan (magnetic resonance imaging)
With an MRI scan a picture of the water-rich structures in the body is made by the magnetization of the water in the tissues. Fluids (such as brain- and spinal fluid) and softer tissues (brain, spinal cord, nerve tissues) are rich of water and made visible in detail. Bone and air contain no water and are therefore better visualised on a CT scan. MRI stands for magnetic resonance imaging. An MRI scan shows best the soft tissues of the body of all radiological studies. MRI is not suitable for people who wear metals in their body or a pacemaker. Titanium is non-magnetic, so people with titanium implants can have an MRI exam.
During the examination the patient lies in a long tunnel tube. People who suffer from claustrophobia may have a stuffy feeling in this tunnel. The survey takes less than half an hour, and it is important that the patient lies still to prevent blurry images. Generating the magnetic field is accompanied with much noise and the machine makes a thumping sound. Some people may tollerate the narrow tube of the MRI because of claustrophobia. Sometimes pre-soothing medication is given.
