    摘要:

    目的 探究手机普视3D SLAM AR软件在颅内幕上浅表肿瘤术前定位的价值。方法 分析10例颅内幕上浅表肿瘤患者的临床资料,病变直径2.3~6.8 cm。术前利用MRI或CT扫描数据对肿瘤、头部轮廓、鼻部及双侧耳廓进行三维重建,载入普视3D SLAM软件,进行肿瘤术前定位(实验组),同时利用传统定位方法进行徒手定位(对照组),最后利用神经导航定位病变中心点作为评价标准,普视3D SLAM软件与徒手定位的中心点与导航定位的中心点之间的距离为定位误差,对结果进行统计学分析。结果 普视3D SLAM软件的定位误差[(0.48±0.04)cm]小于徒手定位法[(2.08±0.23)cm](P<0.05)。结论 普视3D手机AR软件Slam模块对颅内幕上浅表肿瘤定位较传统徒手定位法更准确,此外还能直观显示病变周围的皮层静脉、纤维束等结构,有助于合理地制定术前计划,最大程度地减小手术创伤。 [国际神经病学神经外科学杂志, 2022, 49(3): 32-35.]

    Abstract:

    Objective To explore the value of a smartphone-based augmented reality technique (Persp 3D SLAM software) in preoperative localization of superficial supratentorial tumors.Methods Ten patients with superficial supratentorial tumors (2.3 to 6.8 cm in diameter) were included. Preoperative MRI or CT data were used to perform 3D reconstruction of the tumor, head contour, nose, and bilateral auricles, which were then loaded into Persp 3D SLAM for preoperative tumor localization. Traditional manual localization was also conducted as the control. The accuracy of localization was evaluated by positioning error, which was the distance between the tumor center positioned by either method and that by neuronavigation.Results The positioning error of Persp 3D SLAM was significantly smaller than that of the traditional method (0.48±0.04 cm vs 2.08±0.23 cm, P <0.05).Conclusion The Persp 3D SLAM software shows higher accuracy than the traditional manual method in localizing superficial supratentorial tumors, and can provide direct visualization of cortical veins and fiber tracts around the tumors, facilitating reasonable preoperative plans and minimizing surgical injuries.
