No special preparation is required. If intravenous contrast material is needed, you must not eat two hours before the examination. We will also need laboratory test results dated within two weeks of the MRI scan for kidney function.
You will be asked to lie on your back in the machine. Images of the skull will be prepared usually in three planes and in various sequences according to protocols set for each disorder. The scanning takes 35-45 minutes, is not encumbering, but you will have to lie completely still throughout the process. The results will not be of a quality to be evaluated, should you move. You will also be required to fill and sign a consent form.
