已经开发了一系列用于计算机断层扫描（CT）引导的脑病变活检和囊肿抽吸的协调仪器：一种相对没有CT伪影的塑料引导针，一种用于多向采样的球窝固定装置，以及一种可靠地产生一致组织核心的抽吸切割活检针。对24例患者进行了26例活检和/或抽吸手术，总体活检成功率为79%。该方法对高度恶性星形细胞瘤最可靠，对转移瘤和不寻常的原发肿瘤最不可靠。并发症3例，肿瘤内血肿2例，出血死亡1例。一项已发表的CT活检系列调查显示，总体成功率为85%。严重并发症发生率为3.5%（包括3例死亡）。肿瘤内血肿临床无症状或伴有相对较小的临床问题的发生率为9%。ct引导下的颅内活检比早期的徒手方法更可靠，比立体定向技术更简单。这是选择的程序经皮活检浅表和深部半球病变。
A coordinated series of instruments has been developed for use in computed tomography (CT)-guided brain lesion biopsy and cyst aspiration: a plastic guide needle that is relatively free of CT artifacts, a ball-and-socket holding device for multidirectional sampling, and an aspiration-cutting biopsy needle that reliably produces consistent cores of tissue. Twenty-six biopsy and/or aspiration procedures have been performed on 24 patients with an overall biopsy success rate of 79%. The method is most reliable with highly malignant astrocytomas and least reliable with metastases and unusual primary tumors. There were 3 complications: 2 intratumoral hematomas and 1 death due to hemorrhage. A survey of published CT biopsy series shows an overall success rate of 85%. The rate of serious complications is 3.5% (including 3 deaths). The incidence of intratumoral hematomas that are clinically silent or associated with relatively minor clinical problems is 9%. CT-guided intracranial biopsy is more reliable than the earlier freehand methods and simpler than stereotactic techniques. It is the procedure of choice for percutaneous biopsy of superficial and deep hemispheric lesions.
