The neuroradiologist's contribution to stereotactic neuro-radio-surgery

This publication is literally the same paper (having the same title and image material) which was previously presented at the International Symposium on Stereotactic Neuro-Radio-Surgery (Vienna, October 1992). Any actual updating of the topic has been avoided for reasons of historical accuracy and in order to document the atmosphere of that symposium which was then dominated by the unfolding of a new technology of intracranial lesion treatment. The neuroradiologist's contribution to this modality of treatment has to be the imaging and localizing such lesions accurately, as well as advising colleagues who plan radiosurgery and warning them about possible pitfalls. If there is no close cooperation between radiosurgeons and neuroradiologists, or if neuroradiological assistance is even disregarded, radiosurgical activities may fail.
