在肝脏肿块中发现肿瘤血管及其特征，对于鉴别诊断、选择治疗方案、评估预后而言，是十分重要的。彩色多普勒血流显像（彩超）作为一种无创伤、简便易行、实时成像的影像学检查，已经广泛用于评价肿瘤的血管性。但是，对于肿瘤内细小血管、低速血流或较深部位的血流显示效果并

Color Doppler flow imaging (Color Doppler ultrasound) as a non-invasive, easy-to-use, real-time imaging imaging examination has been widely used to evaluate the vascularity of tumors. However, it shows the effect of blood flow in small blood vessels, low blood flow, or deep parts of tumors.
