摘要目的:探讨术前多模态影像融合三维重建技术在脑肿瘤手术中的应用价值。方法:选择珠海市人民医院神经外科自2019年10月至2020年9月收治的46例脑肿瘤患者，采集其术前头颅CT及MRI资料，并利用美国GE公司AW工作站软件将上述多种影像数据进行配准融合、三维重建，以构建出脑肿瘤及其周围解剖结构的三维数字化影像，并以此设计手术入路及手术计划，术后应用术者一致性等级评价其应用价值。结果:融合重建后的三维数字化影像可清晰显示脑肿瘤的大小、位置、形状以及其与周围结构的解剖关系，并与术前原始影像及术中所见基本相符。46例患者中肿瘤全切除43例、部分切除3例，术后均无手术入路相关并发症发生。术前多模态影像融合三维重建技术的应用价值评价结果为价值突出者36例、有价值者8例、无价值者2例。结论:术前多模态影像融合三维重建技术在脑肿瘤手术中可以提供大量的可视化信息，有效指导手术入路的选择以及脑肿瘤的精准切除。

abstractsObjective:To explore the application value of preoperative multimodal image fusion 3D reconstruction technology in brain tumor surgery.Methods:The preoperative cranial CT and MR imaging data of 46 patients with brain tumors admitted to our hospital from October 2019 to September 2020 were collected. The image registration and fusion of above imaging data were performed by AW workstation software (GE company), and 3D reconstruction was performed to construct 3D digital anatomic image of brain tumor and its surrounding anatomic structure. Based on this, the surgical approach and surgical plan were designed, and its application value was evaluated by consistency grading.Results:The reconstructed 3D digital anatomical image could clearly show the size, location, shape of the tumors and the anatomical relationships between the tumors and surrounding structures, which was consistent with the original image before and during the surgery. Among the 46 patients, 43 were completely resected and 3 were partially resected. There were no approach-related complications after surgery. The application value of preoperative 3D image fusion was evaluated as 36 with outstanding value, 8 with value, and 2 without value.Conclusion:Preoperative multimodal image fusion 3D reconstruction technology can provide a large amount of visual information during brain tumor surgery, guide the choice of surgical approach and precise resection of tumors.
