摘　　要：目的评估MRI及CT图像三维重构及图像融合在颅脑肿瘤中的临床应用价值。方法选取经MRI检出并均行高分辨CT(HRCT)扫描的28例颅脑肿瘤患者,将同一患者的MRI及CT影像数据导入Mimics软件进行三维重构及图像融合,并对所获得图像在肿瘤形态显示及颅骨受累等方面分别与MRI或CT图像进行比较分析。结果三维重构图像直观展示了肿瘤的三维空间位置;在显示肿瘤及邻近颅骨受累范围方面,较MRI、CT图像有优势。结论基于MRI及CT影像数据所获得的颅脑肿瘤三维重构图像能直观显示肿瘤空间立体位置和邻近颅骨受累状况,可为临床教学及手术提供有益的帮助。Objective To evaluate the clinical application of three-dimentional(3D) reconstruction and fusion of MRI and CT images in brain tumors. Methods Methods The MRI and high resolution CT image data of brain tumors in 28 patients was imported into the reconstruction software Mimics, and then the 3D imaging models of brain tumors were reconstructed and compared with the MRI or CT image alone for displaying tumor morphology and skull invasion. Results The 3D reconstruction and fusion of MRI and CT images could display the 3D location of brain tumor and show more information of invaded skull, margin and surrounding tissues of tumor than MRI or CT image alone. Conclusion Conclusion The 3D reconstruction and fusion of MRI and CT images could provide superior understanding of brain tumors, especially for the lesions invading skull, which would be helpful for brain surgery.
