目的探讨超声造影技术对小肝癌的临床价值,为临床工作提供参考依据。方法回顾性分析2011年10月至2012年9月间收治的75例经病理证实的小肝癌患者临床资料,包括常规超声、超声造影及病理资料。结果病理诊断结果显示,75例患者中,中-低分化癌42例,高分化癌23例,透明细胞癌10例。常规超声提示,恶性和可疑恶性38例,小肝癌的诊断符合率为50.7%(38/75);超声造影后提示恶性和可疑恶性69例,小肝癌的诊断符合率为92.0%(69/75)。超声造影诊断符合率显著高于常规超声,差异有统计学意义(χ2=27.5847,P<0.01)。结论超声造影技术对小肝癌的诊断符合率高于常规超声,对小肝癌具有更高的定性诊断价值,值得临床借鉴。
Objective To investigate the clinical value of contrast-enhanced ultrasound in the diagnosis of small hepatocellular carcinoma (HCC) and provide a reference for clinical practice. Methods The clinical data of 75 patients with pathologically confirmed small hepatocellular carcinoma admitted from October 2011 to September 2012 were analyzed retrospectively, including conventional ultrasound, contrast-enhanced ultrasound and pathological data. Results The pathological findings showed that among the 75 patients, 42 cases were moderate-poorly differentiated carcinoma, 23 well-differentiated carcinoma and 10 clear cell carcinoma. Conventional ultrasonography showed malignant and suspicious malignant tumors in 38 cases and small hepatocellular carcinoma in 50.7% (38/75) cases. Ultrasonography showed malignant and suspicious malignancies in 69 cases and small hepatocellular carcinoma in 92.0% (69/75) ). The coincidence rate of contrast-enhanced ultrasound was significantly higher than that of conventional ultrasound (χ2 = 27.5847, P <0.01). Conclusion The coincidence rate of CEUS in the diagnosis of small hepatocellular carcinoma is higher than that of conventional ultrasound, and it has a higher value of qualitative diagnosis for small hepatocellular carcinoma. It is worthy of clinical reference.
