摘要
目的:探讨超声造影(CEUS)在肝硬化合并肝内局灶性小病灶(≤3.0 cm)中的诊断价值。方法:选择我院自2010年4月至2014年8月患有肝硬化合并肝内局灶性小病灶的患者100例,采用MRI、CT及病理确定病灶良恶性,同时对比影像结果,计算常规超声和CEUS的准确性。结果:MRI、CT及病理确定病灶105个,其中恶性组45例,良性组60例,超声造影技术能清晰的显示出血流灌注的情况以及动脉相、门脉相及延迟相的特点。数据统计结果显示常规超声和CEUS的准确性、特异性和敏感性分别为59.05%、77.78%、45.00%和95.24%、95.56%、95.00%,两者之间的差异具有统计学意义(P<0.05)。结论:相对于常规超声,CEUS对患有肝硬化合并肝内局灶性小病灶的患者具有更高的诊断价值。
Objective： To explore the diagnosis value of contrast enhanced ultrasound（CEUS） in cirrhosis complicated with hepatic focal lesions（≤3.0cm）. Methods： A total of 100 patients with cirrhosis complicated with hepatic focal lesions, who were admitted to First Affiliated Hospital of Chengdu Medical College from April 2010 to August 2014, were selected and the benign or malignant lesions were diagnosed by MRI, CT and pathology. The imaging results were compared, and the accuracy of conventional ultrasound and CEUS were calculated. Results： There were 105 lesions identified by MRI, CT and pathological, among which, there were 45 malignant lesions in malignant group and 60 benign lesions in benign group. CEUS clearly showed the blood perfusion status and the characteristics of arterial phase, portal phase and delayed phase. Statistical results showed that the accuracy, specificity and sensitivity of conventional ultrasound and CEUS were 59.05%, 77.78%, 45.00% and 56.19%, 95.56%, 95.00% respectively, the differences were statistically significant（P〈0.05）. Conclusion： CEUS has a higher value in diagnosing cirrhosis complicated with hepatic focal lesions compared with conventional ultrasound.
