This study deals with the use of microcomputer graphic analysis of preoperative magnetic resonance imaging (MRI) scans in functional neurosurgical procedures. Three patients (2 treated for thalamotomy and 1 for thalamic stimulation) had preadmission MRI scans which delineated the classic internal landmarks used in functional neurosurgery. These data were then manipulated and stored using a microcomputer-based graphic analysis system. Intraoperative pattern matching of preadmission graphics with the intraoperative skull X-rays allowed determination of the planned target in the x, y and z coordinates. The accuracy of the graphics FM-PC and AC-PC points was confirmed with the use of ventriculography, stimulation, and postoperative MRI scans. This simple, inexpensive method obviates the need for ventriculography, sedation, intraoperative MRI with a scan-compatible frame, and has the accuracy necessary for functional procedures.
本研究探讨了在功能性神经外科手术中使用术前磁共振成像（MRI）扫描的微机图形分析。三名患者（2例行丘脑切开术，1例行丘脑刺激术）入院前进行了MRI扫描，描绘了功能性神经外科手术中使用的经典内部标志。然后使用基于微机的图形分析系统对这些数据进行处理和存储。将入院前图形与术中颅骨X线进行术中模式匹配，从而确定x、y和z坐标中的计划靶点。通过脑室造影、刺激和术后MRI扫描证实了图形中前连合-后连合（FM-PC）点和前连合-后连合（AC-PC）点的准确性。这种简单、廉价的方法无需脑室造影、镇静、使用扫描兼容框架的术中MRI，并且具有功能性手术所需的准确性。
