摘要
目的探讨多层螺旋CT(MSCT)三维重建在肝脏肿瘤手术中的应用价值。方法28例经手术证实的肝肿瘤患者术前均行MSCT,采用增强双期扫描,并使用三维重建技术完成三维成像,同时将影像结果与术中结果对照,分析其应用价值。结果合适的扫描和增强技术可获得良好的血管成像,能可靠地显示血管形态和病变,术前准确评估肿瘤与邻近血管关系:推移、压迫、包绕或浸润,有利于肝肿瘤的术前可切除性和保留肝容积评估及术中导向。结论多层螺旋CT三维重建能准确的显示肝肿瘤的信息,对制定手术计划有指导意义。
Objective To evaluate the clinical value of three-dimensional （3D） reconstruction of multi-slice computed tomography （MSCT） in the operation of liver neoplasm. Methods Twenty-eight cases of liver neoplasm scheduled for resection were studied with MSCT by two-phase enhancement. The raw data images were processed on a workstation for 3D reconstruction. The findings after processing of the data were compared with those after surgery. Result High quality vascular images could be obtained by optimizing scanning technique and contrast agent administration. The 3D presentation could clearly display the vascular anatomy. Also, the 3D images could accurately depict and evaluate relationship of tumor to vessels such as pad effect, encasement, and involvement. This technique provided the surgeons with information about respectability and a ＂road map＂for planning the liver neoplasm operation. Conclusion 3D reconstruction of MSCT can exhibit the accurate information of the liver neoplasm, and provide better surgical planning and management.
