title: CT-guided stereotaxic biopsy of brain tumors: new technology for an old problem.
abstract: On 63 patients, we used stereotaxic surgery combined with computer tomographic (CT) technology, for reasonably safe and precise biopsy of brain lesions. Histological confirmation was possible in 97% of the cases. More recently, we have also been using the CT-guided stereotaxic technique for brachytherapy, consisting of introduction of an array of radioactive isotope seeds (192Ir). The after-loading cannulas used for the isotope seeds are now also being used for introduction of probes for localized hyperthermia of brain tumors. CT-guided stereotaxic technique is proving to be a major technological advance both diagnostically and therapeutically.
