摘要
目的 探讨动态三维超声造影（3D-CEUS）在显示肝肿瘤血管中的应用价值.方法 选择超声检查发现肝占位患者65例,经手术病理证实或两种以上的影像学检查方法诊断.对病灶行常规超声、二维超声造影（2D-CEUS）和动态3D-CEUS检查,对2D-CEUS及动态3D-CEUS图像进行处理和分析,观察并比较两种造影方式病灶的增强方式及肿瘤血管的空间分布等情况.结果 肝肿瘤的增强方式在2D-CEUS和动态3D-CEUS中的表现一致.两者在显示肿瘤血管的空间分布及立体关系方面比较,差异有统计学意义（P＜0.05）;在动态3D-CEUS中,肝良恶性病变的血管形态比较,差异有统计学意义（P＜0.05）.结论 动态3D-CEUS可更直观、全面地显示肝肿瘤血管的空间立体关系、周边及内部血管的分布形态,为肝肿瘤的超声诊断及临床治疗提供更多的信息.
Objective To investigate the application potentiality of dynamic three-dimensional contrast-enhanced ultrasound （3D-CEUS） in showing vascular patterns of hepatic tumors.Methods Total of 65 hepatic tumors were examined with two-dimensional contrast-enhanced ultrasound （2D-CEUS） and dynamic 3D-CEUS and make statistical comparison between two imaging modes in aspects of enhancement patterns,spatial relationships of tumors and vascularity of different hepatic tumors.Results Dynamic 3D-CEUS showed the same enhancement patterns with 2D-CEUS.However,Dynamic 3D-CEUS was superior to 2D-CEUS in the display of spatial relationships of hepatic tumors and vascularity（P ＜0.05）.The vascularity between benign and malignant hepatic tumors was statistically significant （P ＜ 0.05）.Conclusions Dynamic 3D-CEUS is a useful technique in the differential diagnosis of hepatic tumors as well as 2D-CEUS,and dynamic 3D-CEUS displays the spatial relationship of hepatic tumors and vascularity more visually and comprehensively,which provides additional beneficial information for the diagnosis and therapy of hepatic tumors.
