目的探讨16层螺旋CT增强扫描诊断小肝癌的作用及临床效果。方法对36例患者经B超或甲胎蛋白检查发现高度疑为肝癌患者先采取CT平扫检查为小肝癌患者再作增强扫描检查,然后对2种检查方法的结果进行对比。结果术中共发现肝癌病灶50个。采用CT平扫方法漏检病灶12个,漏检率为24.0%;而采用CT增强扫描方法漏检病灶2个,漏检病灶率为4.0%。两者比较差异有显著性意义(P<0.05)。结论 16层螺旋增强扫描为小肝癌的检出、定性、提供可靠、形象的影像学依据,CT增强扫描应作为临床诊断小肝癌常规检查方法。
Objective To investigate the effect and clinical effect of 16-slice spiral CT in the diagnosis of small hepatocellular carcinoma. Methods Thirty-six patients were examined by B-ultrasound or alpha-fetoprotein. The patients with high suspicion of hepatocellular carcinoma were examined by CT plain scan first and then enhanced scan by small CT scan. Then the results of the two methods were compared. Results A total of 50 liver cancer lesions were found during operation. Twelve lesions were missed by CT scan, with a missed detection rate of 24.0%. Two lesions were missed by CT enhanced scanning, and the missed detection rate was 4.0%. The difference was significant (P <0.05). Conclusions The 16-slice spiral CT scan provides a reliable and vivid imaging basis for the detection and characterization of small hepatocellular carcinoma. CT enhanced scanning should be used as a routine method for routine diagnosis of small hepatocellular carcinoma.
