摘　　要：目的观察肝脏恶性肿瘤的超声造影灌注过程及回声变化规律,探讨超声造影对肝脏恶性肿瘤的诊断价值。方法回顾性分析85例肝脏恶性肿瘤100个病灶超声造影增强模式,分析与二维图像、CDFI的关系。结果造影后肝脏恶性肿瘤具有不同的特征性血管增强表现,与其不同的病理结构相关。结论肝脏恶性肿瘤超声造影后根据其典型的增强模式,多数可作出明确的诊断;对不典型的灌注模式需结合增强CT、MRI或穿刺活检来协助诊断。Objective To investigate the perfusion and echogenicity of liver malignant neoplasms with contrast- enhanced ultrasound （CEUS） and to discuss the diagnostic value. Methods 85 cases with 100 liver malignant neoplasms were retrospectively reviewed. The whole manifestation phase were observed and the relationship of the images with B - mode image and CDH were analyzed. Results After administration of Sono Vue, all the lesion were variously enhanced on real time gray - scale contrast tuned imaging （CnTI）. The blood flow characteristic in lesion had relation with various pathologic construction of liver neoplasms. Conclusion Identification of the typical enhancement patterns of liver malignant neoplasms could improve the diagnostic ability of CEUS. But the diagnosis of atypical enhancement patterns is difficult and still requires enhanced CT, MRI or biopsy.
