When a CT-guided stereotactic technique for functional neurosurgery is adopted, extremely precise targeting is needed to obtain satisfactory surgical results. In this study the authors have investigated the accuracy of the target points determined by CT-guided techniques and compared with those of conventional roentgenographically controlled stereotactic procedures. Stereotactic surgery, employing the Brown-Roberts-Wells (BRW) system, was performed contemporarily 26 times in 23 patients, that is, 9 times in 8 patients for functional neurosurgery using with the roentgenographic method, and 17 times in 15 patients with the CT-guided method only for intracranial neoplasm biopsy. As a result, there were no problems of accuracy of determining the target points by CT-guided stereotactic surgery with the BRW system. When applying this technique for functional neurosurgery, it should be pointed out that there could be a discrepancy within 2 mm from the conventional target determination.
当采用CT引导的立体定向技术进行功能性神经外科手术时，需要极其精确的靶向定位才能获得满意的手术效果。在本研究中，作者调查了CT引导技术确定的靶点的准确性，并与传统X线控制的立体定向手术的靶点准确性进行了比较。使用布朗-罗伯茨-韦尔斯（BRW）系统进行的立体定向手术在23例患者中同期进行了26次，即8例患者中9次使用X线方法进行功能性神经外科手术，15例患者中17次仅采用CT引导方法进行颅内肿瘤活检。结果，使用BRW系统的CT引导立体定向手术在确定靶点方面没有准确性问题。在将该技术应用于功能性神经外科手术时，应该指出，与传统的靶点确定相比可能存在2毫米以内的差异。
