目的分析实时灰阶谐波超声造影和增强MRI显示复发性肝癌血流动力学的特点.方法分析经手术或穿刺病理证实为肝细胞肝癌复发的39例共43个肿瘤的实时灰阶谐波超声造影和增强MRI检查资料.比较复发性肝细胞肝癌在超声造影和增强MRI不同时相中的动态增强及减退表现.结果 100％(43/43)肿瘤在超声造影和增强MRI检查中动脉期均增强.30.2％ (13/43)肿瘤超声造影和增强MRI均表现为动脉期增强,门脉期不减退.37.2％ (16/43)肿瘤超声造影和增强MRI均表现为动脉期增强,门脉期减退.延迟期60.5％(26/43)肿瘤超声造影和增强MRI均表现为增强减退,7.0％(3/43)均表现为持续不减退.超声造影和增强MRI显示67.4％(29/43)复发性肝细胞肝癌的动态增强减退变化规律一致,两种检查方法反映的复发性肝癌的血流动力学规律无显著差异.结论超声造影和增强MRI显示复发性肝细胞肝癌的动态增强减退变化相一致,均能反映肿瘤的血流动力学特点.

Objective To compare the hemodynamics features of recurrent hepatocellular carcinoma between contrast-enhanced ultrasonography (CEUS) and contrast-enhanced MRI (CEMRI).Methods Forty three recurrent hepatocellular carcinoma lesions in 39 patients were evaluated by CEUS and CEMRI.All lesions were proved by operation or needle biopsy.The dynamic enhancement and washout process on CEUS and CEMRI were analyzed.Results On both two methods,all lesions showed hyperenhancement.Among which,30.2％ (13/43) lesions showed hyperenhancement during arterial phase and no washout was found during portal venous phase,37.2 ％ (16/43) lesions hyperenhanced during arterial phase and washout during portal venous phase.During late phase,the enhancement of 60.5％ (26/43) lesions decreased and 7.0％ (3/43) lesions showed no washout on CEUS or CEMRI.The overall concordance ratio between two methods was 67.4％ (29/43).Difference of hemodynamics features between CEUS and CEMRI was not statistically significant.Conclusions CEUS can accurately display the hemodynamic features of recurrent hepatocellular carcinoma,and enjoy high consistence with CEMRI.
