Biopsies can be performed directly with computerized tomography (CT) head scanners with some difficulty. The small scanning orifice does not allow enough room for needle placement; therefore, biopsy is difficult. In contrast, the scanning orifice of the CT body scanner is large enough to permit biopsies without hindrance. Over 300 CT-guided abdominal biopsy procedures have been performed at the Cleveland Clinic Foundation. We are reporting the technique and the results of 14 CT-guided brain biopsies. There were no complications in the series and an accurate diagnosis was made for 13 of the 14 patients.
使用计算机断层扫描（CT）头部扫描仪直接进行活检存在一定困难。其扫描孔较小，没有足够空间放置穿刺针，因此活检操作难度较大。相比之下，CT体部扫描仪的扫描孔足够大，可以毫无阻碍地进行活检。克利夫兰诊所基金会已进行了300多例CT引导下的腹部活检手术。我们现报告14例CT引导下脑活检的技术及结果。该系列病例无并发症发生，14例患者中有13例获得了准确诊断。
