摘要
目的探讨超声造影对转移性肝癌的诊断价值。方法分析62例转移性肝癌的常规超声及超声造影特点。结果超声造影较常规超声新发现病灶68个，其中位于膈下、肝圆韧带旁的新病灶24个，占35％；直径小于10mm的新病灶38个，占56％。门脉相团块周边环状增强为转移性肝癌的特征性表现。结论超声造影较常规超声大大提高肝内转移病灶的检出率，尤其是位于超声扫查盲区的病灶及直径小于10mm的病灶，可为临床诊疗提供更多信息。
Objective To explore the clinical value of contrast - enhanced uhrasonography （CEUS） in metastatic hepatic carcinoma （MHC）. Methods The routine ultrasound images and contrast - enhanced imaging features of 62 patients with MHC were analyzed retrospectively. Results Compared with routine ultrasound, 68 new metastases were found in CEUS, 24 of them （35 % ） were close to the diaphragm or around the ligamentam teres; 39 of them （58%） were smaller than 10mm. Ring enhancement in the portal phase was the characteristic image of MHC. Conclusion Compared with routine ultrasound, CEUS can improve detection rate of MHC, especially for those smaller than 10mm and those in the dead zone. It also provides more information for clinical treatment.
