Stereotactic Imaging

This requires the application of a set of standard reference points, or a "fiducial system", around the head followed by the acquisition of radiological images. The images obtained provide information about the precise spatial position of anatomical and pathological structures in relation to the fiducial system. The highest precision is achieved using a stereotactic frame fixed to the skull before imaging. It is usually carried out under local anesthetic for all adults unless claustrophobia prevents this. Children aged over 12 years are also treated with local rather than general anesthetic. Where the lesion is large, it is acceptable to use a less precise fiducial system, based on a dental imprint and straps to fix to the skull.

With the stereotactic frame in situ, images are taken to demonstrate the pathological lesion. In most patients this consists of a magnetic resonance imaging (MRI) scan. In the case of arteriovenous malformations (AVMs), a high-quality arterial angiogram is used. The
