原发性骨肿瘤的超声诊断及CDFI表现

目的：探讨二维超声及CDFI技术检查在原发性骨肿瘤的应用价值。材料与方法：采用Acuson128XP/10型电脑彩色声像信。对64例疑为原发性骨肿瘤患者（男36例，女28例）进行二维及彩色多普勒超声检测，测量血流动力学指标，并进行统计分析，结果：骨质破坏、骨膜反应及周围软组织肿物在二维图像中有良好表现，CDFI可清晰地显示肿瘤内的血液开态，恶性骨肿瘤血流速度高于良性骨肿瘤。而RI、PI前者低于后者，通过二维及CDFI观察肿瘤内部血流及血流动力学指标，可对原发性骨肿瘤作出初步诊断。

Application of two-dimentional ultrasonography and CDFI in diagnosis of primary bone tumor

Objective:To study the diagnostic value of two dimentional ultrasonography and CDFI in primary bone tumors Materials and Methods:The hemodynamic parameters such as Vmax,Vmin,RI and PI of intratumoral flow in 64 patients(36 males and 28 females) with primary bone tumors proved by histopathology, were studied by using US and CDFI techniques.Results:Through the study of 64 patients,it was essentially revealed bone destruction,periosteum response and soft tissue mass with US techniques.As CDFI showed clearly intratumoral flow feature, the hemodynamic parameters such as Vmax,Vmin,RI and PI of intratumoral flow were examined. The results showed the peak flow velocity in malignant was higher than that in benign.The value of RI and PI in malignant were lower than those in benign.Conclusion:On the base of 2 D ultrasonography,CDFI could show clearly intratumoral flow feature and primary bone tumors were preliminarily diagnosed by 2 D ultrasonography and CDFI.
