Computed tomography has been utilized to guide a needle into central nervous system lesions as small as one centimeter in diameter. Direct puncture has drained many abscesses effectively, provided material for immediate Gram stain and subsequent culture, and permitted irrigation with appropriate antibioties, Multilocular cerebral lesions and loculated extracerebral fluid collections have been aspirated and treated with this technique. Aspiration of known cystic tumors has reduced their mass and obviated some palliative decompressions. Unresectable gliomas and metastases have been biopsied prior to chemotherapy or radiotherapy. Hemorrhage and other rare complications of biopsy may be detected and immediately treated.
计算机断层扫描已被用于引导针穿刺进入直径小至1厘米的中枢神经系统病变。直接穿刺有效地引流了许多脓肿，提供了用于即时革兰氏染色和后续培养的材料，并允许用适当的抗生素进行冲洗。多房性脑病变和局限性脑外液体积聚已通过该技术进行抽吸和治疗。已知囊性肿瘤的抽吸减少了其肿块并避免了一些姑息性减压。不可切除的胶质瘤和转移瘤已在化疗或放疗前进行活检。活检的出血和其他罕见并发症可被检测到并立即治疗。
