The application of multi-modal image fusion combined with navigation technology to precisely localize spinal cord lesions

Objective: To study the application value of multi-modal image fusion combined with navigation for precise localization of spinal cord lesions. Methods: From November 2015 to January 2022, a total of 28 patients with spinal cord lesions were enrolled in the study, and intraoperative CT images were obtained by O-arm, and preoperative MRI and intraoperative CT were fused by navigation system to reconstruct 3D models of the spine and lesion. Complete the localization and resection of spinal cord lesions during navigation, and record basic patient information, image fusion time, and navigation accuracy. Results: All 28 patients successfully localized spinal cord lesions with multi-modal image fusion combined with navigation. The time of image processing was between 7 min and 19 min, and the mean value was 15.3±2.2min. The navigation error was between 0.9mm and 5.3mm, the mean value was 1.8±0.9mm. Conclusion: The multi-modal image fusion combined with navigation can be used to precisely localize spinal lesions, providing a more objective basis and a new approach for individualized and precise surgical planning.
