The authors describe their initial experience with the new pallidotomy targeting software for the COMPASS system. As COMPASS permits window and contrast settings to be changed at any time, multiple imaging modalities can be employed for targeting. This feature allowed the incorporation of fast-spin echo/inversion recovery (FSE/IR) magnetic resonance images (MRI) into the planning protocol. COMPASS has now been employed for 33 consecutive pallidotomies over the last year (July 96-June 97). A statistically significant reduction in the number of microelectrode recording trajectories required to physiologically localize sensorimotor globus pallidus interna (GPi) is noted in these cases as compared to the 41 cases performed in the previous year with a different computer planning system. The authors conclude that the COMPASS system accurately and efficiently targets the internal pallidum when FSE/IR MRI is employed. Nevertheless, pallidotomy should not be performed without neurophysiological localization.
作者描述了他们使用COMPASS系统新型苍白球切开术靶向软件的初步经验。由于COMPASS允许随时更改窗口和对比度设置，因此可以采用多种成像方式进行靶向。这一特性使得快速自旋回波/反转恢复（FSE/IR）磁共振成像（MRI）能够纳入规划方案。在过去一年（1996年7月至1997年6月），COMPASS已连续用于33例苍白球切开术。与上一年使用不同计算机规划系统进行的41例手术相比，这些病例中在生理上定位感觉运动性内侧苍白球（GPi）所需的微电极记录轨迹数量有统计学意义的减少。作者得出结论，当采用FSE/IR MRI时，COMPASS系统能准确、高效地靶向苍白球内部。然而，在没有神经生理定位的情况下不应进行苍白球切开术。
