方法用创伤法制作假性动脉瘤动物模型10例，对动脉瘤的血流模式及各部位流速及压力进行检测，对所测结果进行分析。
Methods the experimental animal models of traumatic pseudoaneurysm were made by means of trauma method. Hemodynamics of the10animal models was studied and analysed.
结论：CDE是较CDFI更敏感的彩色血流显示模式。
Conclusion: CDE is of more sensitive flow display mode than CDFI.
但是，仅根据CEUS增强模式所反映的血流灌注情况，对鉴别息肉样病变良、恶性的价值有限。
However, CEUS is most useful in reflecting blood perfusion patterns; it had limited value in differentiating the malignancies of polypoid lesions.
