摘　　要：目的:观察超声造影对肝转移癌的灌注过程及回声变化规律,探讨超声造影对转移性肝癌的诊断应用价值。方法:采用超声造影技术对26例共47个转移性肝癌病灶进行超声造影,分析研究其造影增强各时相的特征。结果:动脉相47个病灶均可见增强,28个(59.6%)为快速弥漫增强,15个(31.9%)为快速环状增强,4(8.5%)个较大的病灶呈缓慢不均匀轻度增强;延迟相43个病灶(91.5%)呈边界清晰的低回声,5例(10.6%)发现更多的肝内病灶。超声造影47个转移性肝癌中,43个(91.5%)表现为快进快出。结论:转移性肝癌超声造影表现的观察并且对恶性肿瘤肝转移病灶的个数、位置的确定,特别是对延迟相临床前期的微小转移灶的检出,对于恶性肿瘤病人的临床分期及其后续选择治疗方案有较高的临床意义。Objective： To investigate the perfusion and echogenicity of liver metastasis using contrast tuned imaging and to discuss the role of gray-scale contrast-enhanced ultrasonography（ CEUS）in the diagnosis of liver metastasis in comparison with non-enhanced ultrasound（ US） and enhanced CT. Methods： 26 Patients with 47 untreated liver metastasis underwent CEUS. The characteristic appearances of CEUS in different vascular phases were observed. Results： All the 47 lesions showed enhancement but with varied appearances,28（ 59. 6%） showed early diffuse enhancement,15（ 31. 9%）showed ring-like enhancement,and 4（ 8. 5%） lesions of large size showed slowly inhomogenous minor enhancement in the late phase,sharp defects were found in 43（ 91. 5%） lesions,and more lesions were detected in 5 patients（ 10. 6%）. Of 47 Metastasis,43（ 91. 5%） were identified as fast-in and fast-out enhancement pattern. Conclusions： In the arterialphase,the perfusion patterns of liver metastasis in gray-scale CEUS,especially the early detection of small and minute liver metastasis lesions are useful for stage diagnosis and treatment methods＇ selection of malignance patients.
