摘　　要：目的探讨钆塞酸二钠(Gd-EOB-DTPA)增强MRI与螺旋增强CT对肝脏局灶性病变的诊断价值。方法收集2017年10月—2018年11月我院诊治的肝脏局灶性病变病灶51例,所有患者经钆塞酸二钠增强MRI和螺旋CT增强扫描,51例病灶均经过病理或随访证实。比较钆塞酸二钠增强MRI和螺旋增强CT在肝脏局灶性病变上的检出率、准确率及典型影像表现之间的差异。结果51例肝脏局灶性病变包括诊断肝硬化结节5例,肝血管瘤16例,局灶性结节增生8例,肝细胞肝癌8例,肝转移14例。钆塞酸二钠增强MRI检出所有病灶,诊断准确率为96.1%;螺旋增强CT检出率为70.6%,诊断准确率为49.0%。钆塞酸二钠增强MRI检出率及诊断准确率均明显高于螺旋增强CT,差异具有统计学意义(P<0.05)。结论Gd-EOB-DTPA增强MRI有助于肝脏局灶性病变的诊断和鉴别诊断,具有重要的临床应用价值。Objective To investigate the application value of Gd-EOB-DTPA enhanced MRI and spiral enhanced CT in the diagnosis of focal liver lesions(FLLs).Methods A total of 51 cases diagnosed with FLLs from Octorber 2017 to November 2018 were collected.The Gd-EOB-DTPA enhanced MRI and the spiral enhanced CT were performed in all patients.All the foci were confirmed by pathology or follow-up.The differences in detection rate,accuracy rate and typical imaging findings were compared.Results There were 51 FLLs,including 5 cases of liver cirrhotic nodules,16 cases of hepatic hemangioma,8 cases of focal nodular hyperplasia,8 cases of hepatocellular carcinoma and 14 cases of hepatic metastases.All the lesions were detected by Gd-EOB-DTPA enhanced MRI and its diagnostic accuracy rate was 96.1%.The lesion detection rate and diagnostic accuracy rate of spiral enhanced CT were 70.6%and 49.0%,respectively.The detection rate and accuracy rate of Gd-EOB-DTPA enhanced MRI were both higher than that of spiral enhanced CT(P<0.05).Conclusion Gd-EOB-DTPA enhanced MRI is helpful in the diagnosis and differential diagnosis of FLLs,which has important clinical value.
