摘要
目的 探讨超声造影在肝局灶性病变诊断中的临床应用。方法 选取我院350例肝局灶性病变患者为研究对象,将其超声造影（悦耘哉杂）表现与病灶增强CT检查、病理检查结果比较。结果 CEUS敏感性为96.32%,特异性87.70%,阳性预测值97.22%,阴性预测值96.47%,定性准确率93.43%;增强CT敏感性为92.64%,特异性90.37%,阳性预测值82.94%,阴性预测值93.33%,定性准确率91.71%,两组定性准确率比较,差异无统计学意义（P〉0.05）。恶性病灶163例：HCC110例,肝转移瘤（MLC）53例,病灶直径0.5~8.2 cm;良性病灶187例：肝血管瘤64例,局灶性结节样增生（FNH）23例,肝内炎性病灶53例,肝硬化结节35例,肝细胞腺瘤6例,肝囊肿6例,病灶直径1.1~6.7 cm。对恶性病灶行CEUS检查,诊断为恶性病灶154个,有9个局灶性病诊断为血管瘤,最终经病理学检查为转移癌,CEUS对恶性肝局灶性病变的诊断准确度为94.48%。结论 超声造影在肝局灶性病变的定性准确率与增强CT相当,可作为评价肝局灶性病变的有效工具。
Objective To discuss the clinical application of contrast-enhanced ultrasound. Methods Three hundred and fifty cases of patients with liver lesions in our hospital were selected, and the inspection results between ultrasonic imaging performance, lesions enhanced CT examination and pathological examination were compared. Results For CEUS, the sensibility of is 96.32%, the specificity is 87.70%, the positive predictive value is 97.22%, the negative predictive value is 96.47%, and the qualification accuracy is 93.43%; For enhanced CT, the sensitivity is 92.64%, the specificity is 90.37%, the positive predictive value is 82.94%, the negative predictive value is 93.33%, and the qualification accuracy is 91.71%. The qualitative accuracy of the two groups was compared, and the difference was not statistically significant （P〉0.05）. There are 163 cases of patients with malignant lesions, in which 110 cases are HCC, 53 cases are hepatic metastasis, the diameter of lesion is 0.5-8.2 cm; there are 187 cases of benign lesion, in which 64 cases are hepatic hemangioma, 23 cases are focal nodular hyperplasia, 53 cases are intrahepatic inflammatory lesion, 35 cases are hepatic cirrhosis, 6 cases are hepatocellular adenoma, and 6 cases are hepatic cyst, the diameter of the lesion is 1.1~6.7 cm. 154 malignant lesions, 9 focal hemangioma lesions are diagnosed by CEUS examination, and finally diagnosed as metastasesizing cancer. The accuracy of CEUS for malignant liver lesions is 94.48%. Conclusion The qualification accuracy of contrast enhanced ultrasonography for focal liver lesions is the same as contrast enhanced CT, and could be used as an effective tool for the evaluation of focal liver lesions.
