Image-based scalp localization methods currently used are complex and not standardized. The authors have developed a simple yet accurate method for craniotomy localization using multiplanar reconstruction (MPR) algorithms.
In this method, the goal is to localize a projected point (defined as T) of the center of the lesion on the scalp. An oblique coronal plane is reformatted using a patient's magnetic resonance (MR) images with MPR algorithms to include both the center of the lesion and bilateral external auditory meati. Then the distance between T and the ipsilateral external auditory meatus or sagittal suture (defined as S) is measured along the scalp contour in the plane. The distance between the bregma and S is also measured. These distances are used for scalp localization, using a tape measure in the operating room.
We have had successful scalp localization in six clinical cases. It took about 3 min to measure each distance on the MR console.
This method for craniotomy planning using MPR algorithms is simple and sufficiently accurate.
目前使用的基于图像的头皮定位方法复杂且未标准化。作者开发了一种使用多平面重建（MPR）算法进行开颅手术定位的简单而准确的方法。
在该方法中，目标是在头皮上定位病变中心的投影点（定义为T）。使用患者的磁共振（MR）图像通过MPR算法重新格式化一个斜冠状平面，使其包含病变中心和双侧外耳道。然后在该平面中沿着头皮轮廓测量T与同侧外耳道或矢状缝（定义为S）之间的距离。还测量前囟与S之间的距离。在手术室中使用卷尺，这些距离用于头皮定位。
我们在6例临床病例中成功进行了头皮定位。在MR控制台上测量每个距离大约需要3分钟。
这种使用MPR算法进行开颅手术规划的方法简单且足够准确。
