title: Computer-aided, CT-guided biopsy and brachytherapy of brain tumors.
abstract: The authors present the principles of computer-aided, CT-guided stereotaxis as it applies to the modified Riechert-Mundinger equipment. A preliminary report on 20 prospectively biopsied and interstitially radiated patients with cerebral mass lesions is discussed. 192Ir served as the interstitial isotope exclusively. To date the results are encouraging and complement the European experience. However, a great deal of improvement is possible, particularly in the sophistication of interstitial radiation of brain tumors; all well within presently available technology.
