Frameless Stereotaxy for Radiosurgical Planning and Follow-up, target coordinates calculated in 3 dimensions. For CT scanning, cross sections of perpendicular and oblique fiducial markers are seen..For follow-up CT scans done without the frame, a virtual frame is generated by means of a computer program that places fiducial markers on each CT scan cut, as if t

Microsurgery Versus Radiosurgery in the Treatment of Small Acoustic Neurinomas,rve. Many more anatomical and pathogenetic factors are involved that need careful consideration. In small neurinomas, of grades I and II, total extirpation of the tumour with preservation of both the facial nerve and segments of the vestibulocochlear nerve not directly involved by the tumour has bec

The Need for Adjunctive Focused Radiation Therapy in Pituitary Adenomas,d the high rate of pituitary insufficiency have to be weighed against the good sugical and/or medical results in the treatment of these tumours. Unfortunately surgical outcome is almost invariably correlated with invasive growth. Invasiveness is statistically significantly correlated with tumour siz

Gamma Knife Radiosurgery for Metastatic Brain Tumors,tially, a single treatment of 35 to 45 Gy was delivered to the enhanced CT margin. This dose was found to be inadequate for tumor control. We then raised the marginal dose to 50 to 55 Gy, but even this radiosurgical dose did not appear to control tumor growth. However, we have found that metastatic

This atraumatic system was utilized for subsequent stereotactic CT/NMR staging to obtain strictly comparable neuro-imaging. Thus, tumour response was evaluated precisely and radiosurgery repeated (straight after the diagnostic sitting), as needed. No hospitalization or anae
