螺旋CT诊断伴肝硬化小肝癌的观察

目的:探讨螺旋CT诊断伴肝硬化小肝癌的观察。方法:选取我院35例肝硬化小肝癌患者,对所有患者应用螺旋CT进行诊断。结果:门静脉期扫描和肝动脉期扫描的检出率也无明显差距,无统计学意义(P>0.05)。联合动脉期和静脉期后,诊断准确率有所提高,和平扫病灶检出率相比,有统计学意义(P<0.05)。动脉期扫描过程中,出现2个低密度,3个等密度结节漏检的情况,而门静脉扫描有1个低密度,5个等密度结节漏检的情况。结论:螺旋CT诊断伴肝硬化小肝癌,诊断率极高,但是也存在误诊、漏诊的情况,建议应用联合其他方法进行诊断,从而提高诊断准确率。

Objective To investigate the diagnosis of small liver cirrhosis with liver cirrhosis by spiral CT. Methods 35 cases of liver cirrhosis with liver cirrhosis were selected in our hospital, and all patients were diagnosed by spiral CT. Results there was no significant difference in the detection rate between the portal venous phase and the hepatic artery phase scan, and there was no statistical significance(P>0.05). After the combination of arterial and venous phase, the accuracy of diagnosis was improved, and the detection rate of the lesions was statistically significant(P<0.05). During the arterial phase scanning, there were 2 low density and 3 equal density nodules missing. However, there were 1 low density and 5 equal density nodules missing in portal vein scanning. Conclusion Spiral CT is a high diagnostic rate for small hepatocellular carcinoma with cirrhosis, but there is also misdiagnosis and missed diagnosis. It is recommended to combine other methods for diagnosis, so as to improve the accuracy of diagnosis.
