摘　　要：目的探讨超声造影(CEUS)与增强计算机体层扫描(CECT)对肝硬化背景下小肝癌(SHCC)的诊断价值及增强特点。方法选取2012年4月至2014年4月间新疆医科大学第二附属医院感染科住院肝硬化患者198例,分别采用CECT及CEUS诊断。观察两种检测方法对SHCC诊断的敏感度、特异度、正确诊断率和增强特点,评价CEUS对CECT的补充诊断价值。结果 170个SHCC病灶中,CEUS检查发现151个,CECT检查发现132个。CEUS对SHCC诊断的特异度优于CECT(P<0.05),两者诊断的敏感度及正确率比较差异无统计学意义(P>0.05)。CECT和CEUS在SHCC各时期的增强分级比较差异无统计学意义(P>0.05)。CECT漏诊38个SHCC病灶,均经CEUS检出为SHCC,对照病理诊断结果,24个病灶诊断正确。结论 CECT和CEUS对肝硬化背景下SHCC的诊断敏感度、准确度及增强模式相似,均能较好地反映SHCC肿瘤学血供特点,两者联合应用,可提高肝硬化背景下SHCC的诊断准确性。Objective To study the performance characteristics and the similarities and differences of cirrhotic ultrasound （CEUSS） and enhanced CT （CECT） for the diagnose of small hepatocellular carcino- ma （SHCC） in cirrhotic. Methods All of 198 cases of patients with cirrhisis in the department of infec- tious diseases in the Second Affiliated Hospital of Xinjiang Medical University from April 2012 to April 2014 were used the CECT and CEUS for the diagnosis, respectively. The sensitivity, specificity, and diagnostic accuracy rate enhancement features of the two methods were compared. The complement value of CEUS for CECT was evaluated. Results Among 170 SHCC lesions, CEUS examination revealed 151 cases, CECT examination revealed 132 cases. The diagnostic specificity of CEUS was superior to CECT （ P 〈 0.05 ）. There was no statistically significant difference of the sensitivity and diagnostic accuracy of both methods （ P 〉 0. 05）. The enhancement grading of each period between the two methods was no statistically significant difference （P 〉 0. 05 ）. CECT missed 38 SHCC lesions were detected by CEUS and compared with patholog- ical diagnosis, 24 lesions were correctly diagnosed. Conclusions CECT and CEUS in the diagnose of SHCC in cirrhotic are sensitivity, accuracy and the enhanced mode is similar, both can better reflect the characteristics of the blood supply. This article shows the combination of CECT and CEUS can improve diag- nostic accuracy rate of SHCC in cirrhotic.
