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 investigate the clinical effects of conventional ultrasound and contrast-enhanced ultrasound in the diagnosis of focal liver lesions. Methods A total of 60 patients with focal hepatic lesions in our hospital from June 2014 to June 2015 were selected as the study subjects. All patients were given conventional ultrasound and contrast-enhanced ultrasound, and the two methods were observed in the diagnosis results The accuracy of the two methods to evaluate the qualitative diagnosis of focal liver lesions of practical value. Results The accuracy of B-mode ultrasound in the diagnosis of focal liver lesions was 22.7% -85.2%. The results of color Doppler ultrasound were consistent with those of B-mode ultrasonography. However, the accuracy rate of focal nodular hyperplasia 26.3%. Upgrade 52.7%. The diagnostic accuracy of routine ultrasound and contrast-enhanced ultrasound in hepatocellular carcinoma and metastatic liver cancer were all higher than 85% (P <0.05). Diagnostic staff confidence, diagnostic confidence level for the diagnostic level I CDFI was significantly higher than B-US, and CEUS in the diagnosis of hepatocellular carcinoma, metastatic liver cancer and vascular cancer and non-uniform fatty liver diagnostic confidence were> 85%. Conclusion Conventional ultrasonography and contrast-enhanced ultrasonography have very high clinical value in the qualitative diagnosis of focal liver lesions in patients with liver lesions, while the contrast-enhanced ultrasound in focal nodular hyperplasia was significantly higher than the conventional ultrasound examination, suitable for lesion echo is not enough Typical, no more favorable clinical evidence to support the patient’s condition diagnosis, can effectively enhance the doctor’s diagnostic confidence.
