超声及CT鉴别诊断肝硬化背景下肝血管瘤、肝细胞肝癌的临床价值探讨

目的探讨超声及CT鉴别肝硬化背景下肝血管瘤、肝细胞肝癌的临床价值。方法回顾性分析2013年7月至2018年6月收治的110例肝硬化背景下肝血管瘤、肝细胞肝癌患者临床及影像资料,比较CT和超声的诊断准确率,分析CT和超声对肝硬化背景下肝血管瘤和肝细胞肝癌的检出率。结果110例患者中经手术病理检出肝血管瘤共63例,其中超声检出49例,检出率为77.78%;CT平扫检出51例,检出率为80.95%;CT增强扫描检出60例,检出率为95.24%。CT增强扫描的检出率显著高于CT平扫和超声检查(P<0.05);47例肝细胞肝癌患者,超声检出33例,检出率为70.21%;CT平扫检出35例,检出率为74.47%;CT增强扫描检出45例,检出率为95.74%,CT增强扫描的检出率明显高于CT平扫和超声检查(P<0.05)。结论CT和超声检查均可有效显示肝硬化背景下肝血管瘤、肝细胞肝癌的影像学特点,但CT增强扫描对肝血管瘤和肝细胞肝癌的检出率明显高于CT平扫和超声检查。

Clinical Value of Ultrasonography and CT in the Differential Diagnosis of Hepatic Hemangioma and Hepatocellular Carcinoma in the Context of Cirrhosis

Objective To explore the clinical value of ultrasonography and CT in the differential diagnosis of hepatic hemangioma and hepatocellular carcinoma in the context of cirrhosis.Methods The clinical data of 110 patients with hepatic hemangioma and hepatocellular carcinoma under the background of liver cirrhosis from July 2013 to June 2018 were analyzed retrospectively.The diagnosis results of CT examination and ultrasonography were analyzed,and the detection rates of hepatic hemangioma and hepatocellular carcinoma by CT examination and ultrasonography were compared.Results Among the 110 patients,there were 63 cases of hepatic hemangioma detected by surgery and pathology,among which 49 cases were detected by ultrasound,with a detection rate of 77.78%.There were 51 cases were detected by CT plain scan,and the detection rate was 80.95%.CT enhanced scan detected 60 cases with the detection rate of 95.24%.The detection rate of CT enhanced scan was significantly higher than that of CT plain scan and ultrasound(P<0.05).Among 47 patients with hepatocellular carcinoma,33 cases were detected by ultrasound,with a detection rate of 70.21%.There were 35 cases were detected by CT plain scan,and the detection rate was 74.47%.The detection rate of 45 cases by CT enhanced scan was 95.74%.The detection rate of CT enhanced scan was significantly higher than that of CT plain scan and ultrasound(P<0.05).Conclusion Both CT and ultrasound can effectively display the imaging characteristics of hepatic hemangioma and hepatocellular carcinoma in the background of cirrhosis,but the detection rate of hepatic hemangioma and hepatocellular carcinoma by CT enhanced scan is significantly higher than that by CT plain scan and ultrasound.
