摘　　要：目的探讨常规超声(US)检查与64层螺旋CT(CT)检查在肝癌及肝脏局灶性结节增生临床诊断中应用价值。方法 2013年1月至2015年1月对84例经肝细胞穿刺活检或术后病理组织检查确诊为肝脏局灶性病灶分别行US检查及CT检查,分析两种诊断方法准确率,病灶大小数目及患者在US及CT中的影像学特征。结果 US在诊断肝脏良性病变中的符合率与CT相当(P>0.05),而在肝癌诊断中CT组诊断准确率显著高于US组(P<0.05)。CT组在直径≤1cm微小肿瘤诊断中的符合率大于US组(P<0.05)。与肝炎型假瘤、肝局灶性增生结节、肝血管瘤患者相比,原发性肝癌、转移性肝癌患者CT始消时间及持续时间更长(P<0.05)。结论与US相比,CT对肝癌的诊断率更加准确,更尽早分辨出恶性病灶及微小病灶。且不同性质的肝脏局灶性病灶在CT中表现出不同的增强方式,能有效鉴别不同种类的肝脏局灶性病灶。Objective To investigate the examination application value of hepatic focal nodular hyperplasia of routine ultrasound（US）examination and 64-slice CT（CT）of liver cancer and clinical diagnostics.Methods 84 patients with liver cell or a pathological tissue biopsy diagnosed as focal liver lesions were underwented with US examination and CT examination from June 2013 to June 2015.The diagnostic methods,focus the size and number of patients in the US and imaging features of CT of two groups were analyzed.Results The benign liver lesions fairly consistent rate of US and CT were no different（P〈0.05）,while the HCC diagnosis diagnostic accuracy of CT group was significantly higher than the US group（P〉0.05）.The rate in tumor diagnosis≤1cm small diameter of CT Group was greater than US group（P〈0.05）.Hepatitis type pseudotumor,liver focal nodular hyperplasia,hepatic hemangioma compared with patients with primary liver cancer,metastatic liver cancer CT start time and duration were longer elimination（P〈0.05）.Conclusion Compared with US,CT for the diagnosis of liver cancer is more accurate,more distinguish malignant lesions and small lesions as early as possible.And focal liver lesions of different nature in the CT showed a different enhancement method can effectively identify different types of focal liver lesions.
