目的探讨超声造影在肝脏肿瘤诊断中的应用价值。方法选取2012年3月—2014年3月于泸州市中医医院行超声造影检查和彩色多普勒超声检查的疑似肝脏肿瘤患者600例,随机分为观察组与对照组,各300例。对照组患者给予二维灰阶超声和彩色多普勒超声检查,观察组患者给予超声造影检查。观察两组患者肝脏肿瘤的检出率及定性诊断的准确率。结果观察组患者真阳性率和真阴性率高于对照组,假阳性率和假阴性率低于对照组,差异有统计学意义(P<0.05);观察组肝血管瘤、肝细胞癌、肝转移癌、肝内胆管癌的定性诊断准确率高于对照组,差异均有统计学意义(P<0.05)。结论超声造影在肝脏肿瘤诊断中具有较高的应用价值,有助于提高肝脏肿瘤的检出率。
Objective To investigate the value of contrast-enhanced ultrasound in the diagnosis of liver tumors. Methods From March 2012 to March 2014, 600 patients with suspected liver tumor underwent contrast-enhanced ultrasound and color Doppler ultrasound in Luzhou Hospital of Traditional Chinese Medicine were randomly divided into observation group and control group, with 300 cases each. Patients in the control group were given two-dimensional gray-scale ultrasound and color Doppler ultrasonography, while those in the observation group were given contrast-enhanced ultrasound. The detection rate of liver tumors and the accuracy of qualitative diagnosis in both groups were observed. Results The true positive rate and true negative rate in the observation group were higher than those in the control group, and the false positive rate and false negative rate were lower than those in the control group (P <0.05). The hepatic hemangioma, hepatocellular carcinoma, The accuracy of qualitative diagnosis of metastatic carcinoma and intrahepatic cholangiocarcinoma was higher than that of the control group (P <0.05). Conclusion Contrast-enhanced ultrasound in the diagnosis of liver tumors has a high value, which can help improve the detection rate of liver tumors.
