- Does the patient have to be prepared for the investigation?
- How is the examination conducted?
- Is it necessary to use a contrast agent?
Do not eat anything at least 6 hours before the examination if you are planning a MRI of the head using a contrast agent (for example, to identify tumours or as part of a multiple sclerosis diagnosis).
Otherwise, no special preparation is required for the head MRI and only general MRI examination instructions apply.
The radiology engineer will place you in the appropriate position on the examination table and install a suitable coil. You will be provided with earphones for hearing protection as loud noises are generated during the investigation. You will be placed inside the MRI apparatus for the duration of the examination. You will hold a bell in your hand to use it if any problems occur during the procedure to alert the radiological engineer performing the procedure.
It is of particular importance that you remain completely still during the investigation as the movements impair the image quality!
The treatment takes about 30 minutes. The time is extended by an additional 15 minutes if a contrast agent has to be used.
Contrast agent is not routinely used in such examinations, except in special cases, such as to define known tumours, vessel malformation, in multiple sclerosis diagnostics, etc.
