Computed tomography (CT) and magnetic resonance imaging (MRI) studies are used separately for surgical planning of spine surgery. Advanced techniques exist for creating CT-MR fusion images, but at this time these techniques are not easily accessible for large-scale use.
We propose a simple graphical technique for CT-MR image overlay, for use in the surgical planning of spinal decompression and guidance of intraoperative resection. The proposed technique involves overlaying a single cross-section from anatomically comparable MRI and CT studies on any software with basic image editing functions.
We demonstrate CT-MR fusion images of 8 patients of the senior author in which the technique was used. We found that it can also be referenced intraoperatively for navigation.
Compared to other techniques, our proposed method can be easily implemented by clinicians to create simple CT-MRI fusion images that can be useful for preoperative planning and intraoperative navigation.
计算机断层扫描（CT）和磁共振成像（MRI）研究分别用于脊柱手术的手术规划。存在用于创建CT-MR融合图像的先进技术，但目前这些技术不易大规模使用。
我们提出了一种用于CT-MR图像叠加的简单图形技术，用于脊柱减压手术规划和术中切除引导。所提出的技术涉及在任何具有基本图像编辑功能的软件上叠加来自解剖学上可比的MRI和CT研究的单个横截面。
我们展示了8例使用该技术的资深作者的患者的CT-MR融合图像。我们发现它也可在术中用于导航。
与其他技术相比，我们提出的方法可以很容易地由临床医生实施，以创建简单的CT-MRI融合图像，这些图像可用于术前规划和术中导航。
