A method for computed tomography (CT)-based stereotactic biopsy of intracranial neoplasms with arteriographic control is described. Stereotactic CT and digitized stereotactic arteriographic data are input to a three-dimensional computer matrix that corresponds to the coordinate system of a stereotactic frame located in the operating room. A site for biopsy is selected by cursor from the CT display screen. The computer calculates and outputs the mechanical adjustments of the stereotactic frame necessary to place the target point into the focal point of the frame. Horizontal and vertical approach angles are determined from the digitized arteriogram and are displayed as settings on the stereotactic frame that represent an avascular trajectory along which the lesion may be biopsied safely. This procedure has been used successfully in 86 patients, with no morbidity or mortality.
描述了一种基于计算机断层扫描（CT）的颅内肿瘤立体定向活检方法，并结合血管造影控制。立体定向CT和数字化立体定向血管造影数据被输入到一个三维计算机矩阵中，该矩阵与位于手术室的立体定向框架的坐标系相对应。通过光标从CT显示屏上选择活检部位。计算机计算并输出将目标点置于框架焦点所需的立体定向框架的机械调整。水平和垂直进针角度由数字化血管造影片确定，并显示为立体定向框架上的设置，这些设置代表一条无血管轨迹，沿着该轨迹可以安全地对病变进行活检。该方法已成功应用于86例患者，无发病率或死亡率。
