감별진단을 요한 뇌병변의 전산화 단층촬영을 이용한 뇌정위 생검 = CT Guided Stereotaxic Biopsy for the Differential Diagnosis of Brain Lesions

다국어 초록 (Multilingual Abstract)

Some intracranial masses are usually treated following a presumptive diagnosis based on the clinical picture and neurological studies but in some instances a proven histological diagnosis might alter the method of treatment as well as affect the prognosis.
Open surgical biopsy however might cause serious neurological deficit in many of these patients however a stereotaxic approach might avoid such problems.
For the correct three dimensional target localization on CT scan we developed nearly artifact free simplified CT interface frame that accurately interface between the CT scanner and the stereotaxic instrument makes it possible to take biopsies at exact and with low risk.
In 10 patients CT interfaced stereotaxic biopsy of brain lesions were performed. 100 % accurate histological diagnosis was obtained and helped considerably in planning further therapy. The localization error was less than 0.04mm and no significant complications occured in these patients.
