Treatment of small cerebral gliomas with CT-aided stereotaxic curietherapy.

In cases of stereotaxic irradiation of small tumors, CT makes possible a precise determination of tumor volume and dosage and permits exact positioning of the therapy probe. Iridium 192 wires are interstitially implanted in the tumor (mostly gliomas Grades I-III) after biopsy. The results with 98 CT-controlled patients (from a series of 213 implantations in midline tumors) have provided new information about the method of treating small cerebral gliomas.
