摘　　要：目的:探讨双源CT(Dual-source computed tomography,DSCT)在颌面部肿瘤诊疗中的应用价值。方法:7例颌面部肿瘤病人通过双源CT检查,将数据发送至工作站进行多平面重建、容积重建。结果,7例患者均经手术治疗,术中所见肿瘤部位与周围神经、血管、软组织及硬组织关系均与双源CT检查结果一致。结论:双源CT具有扫描速度快,图像清晰的特点,在工作站上三维影像可以任意旋转和切割,从不同角度观察肿瘤与周边血管、神经、软组织及硬组织的关系,为诊断和治疗提供了大量准确信息。Objective： To evaluate the clinical values of the Dual-source computed tomography for diagnosis and treatment in maxillofacial tumors. Method： 7 cases of maxillofacial tumors were examined with Dual-source computed to- mography and then the images were taken with multi-planar reformats and volume rendering technique on work-station. Result： All the patients have been operated. Conclusion： Dual-source CT can be provided with characteristic of ultrafast speed scan and clear images. Three-dimensional CT images were obtained from circumgyration and incision at will on work- station.Pathological changes could be observed from many projection in 3D images. Dual-source CT can offer a lot of infor- mation for constitution plan of treatment. Dual-source CT is a valuable method in diagnosis and treatment of facial fractures, and the combination of 2D-CT and 3D-CT would be the best demonstration.
