摘　　要：目的探讨常规超声和超声造影对肝脏局灶性病变定性诊断的临床效果。方法选取本院2014年6月-2015年6月收治的肝脏局灶性病变患者共60例作为研究对象,本组患者均给予常规超声检查以及超声造影检查,观察两种检查方法在诊断结果中的准确性,评判两种方法对肝脏局灶性病变定性诊断的实用价值。结果 B型超声对肝脏局灶性病变诊断准确率为22.7%-85.2%,彩色多普勒超声检查结果与B型超声检查结果基本保持一致性,然而在局灶结节增生症状中准确率从26.3%.提升52.7%。常规超声与超声造影在肝细胞性肝癌、转移性肝癌症状中诊断准确程度均〉85%,差异有统计学意义（P〈0.05）。诊断人员信心强度方面,诊断人员信心强度为I级的准确率中CDFI明显高于B-US,而CEUS在肝细胞肝癌、转移性肝癌以及血管癌和不均匀脂肪肝方面诊断信心准确率均〉85%。结论常规超声和超声造影在肝脏局灶性病变患者定性诊断检查中均有着极高的临床价值,同时超声造影检查在局灶结节增生准确率上明显高于常规超声检查,适用于病灶回声不够典型、无较为有利临床证据支持的患者的病情诊断,能够有效提升医生的诊断信心。Objective To studythe clinical effect of conventional ultrasound and contrast-enhanced ultrasound in the diagnosis of focal hepatic lesions. Methods Selected in our hospital in June 2014- June 2015,a total of 60 patients with focal liver lesions as the research object,The patients were given conventional ultrasound and contrast-enhanced ultrasound examination,Observe two inspection methods in the diagnosis accuracy,To judge two kinds of methods of qualitative diagnosis of focal liver lesions of practical value. Results The diagnostic accuracy of B ultrasound in focal liver lesions was 22. 7% -85. 2%,Color Doppler ultrasound examination results and the results of B ultrasound examination were basically consistent,But in the symptoms of focal nodular hyperplasia,the accuracy increased from 52. 7% to 26. 3% .The diagnostic accuracy of conventional ultrasound and contrast-enhanced ultrasound in the diagnosis of hepatocellular carcinoma and metastatic liver cancer was more than 85%,The difference was small（ P〈0. 05） .Diagnostic confidence strength,Diagnosis of staff confidence in the strength of the accuracy of a CDFI of grade I was obviously higher than that of B-US,And CEUS in hepatocellular carcinoma,metastatic liver cancer,and the diagnosis of liver cancer and uneven fatty liver were more than 85%. Conclusion Conventional ultrasound and contrast enhanced ultrasound in the diagnosis of focal liver lesions have a high clinical value,At the same time,the accuracy rate of ultrasound contrast examination was higher than that of the conventional ultrasound examination,Is suitable for the diagnosis of the disease in patients with no evidence of the lesion,and no more favorable clinical evidence support,Can effectively improve the doctor＇s diagnostic confidence.
