摘要/Abstract

摘要： 目的分析比较多排螺旋CT与MRI增强扫描原发性肝癌（PLC）肝内病灶的影像学表现及其诊断价值。方法 2014年12月~2016年12月本院收治的经组织病理学检查诊断的肝细胞癌（HCC）患者36例,分别行CT和MRI多期动态增强扫描,分析各自的影像学表现特征,比较两者的诊断效能。结果在36例HCC患者中,共检出病灶48个;检出<3 cm小肝癌14例,病灶16个,>3 cm巨块型肝癌9例,病灶32个;CT动脉期检出43个（89.6%）病灶,门脉期检出39个（81.3%）病灶,延迟期检出40个（83.3%）病灶,而MRI动脉期检出46个（95.8%）病灶,MRI门脉期检出率为52.1%,延迟期检出率为85.4%,组间比较差异显著（x²=14.376,P<0.05）;MRI扫描对PLC病灶包膜的显示优于CT,但差异无统计学意义（P>0.05）;在48个病灶中,经CT增强扫描确诊41个（85.4%）,经MRI增强扫描确诊44个（91.7%）,两者差异无统计学意义（x²=0.924,P>0.05）。结论 CT和MRI多期动态增强扫描均能够充分显示PLC病灶的强化特征,其诊断效能难分伯仲。

Abstract: Objective To investigate the imaging manifestations of hepatocellular carcinoma （HCC） by multiple row spiral CT and MRI enhanced scan. Methods Thirty six patients with HCC proved by histopathological examination were included in this study between December 2014 and December 2016. CT and MRI multiphase dynamic enhanced scan was carried out in all patients. The features of foci was observed and the diagnostic accuracy of CT and MRI was compared. Results Among the 36 patients with HCC,48 lesions were found,and 14 cases with 16 foci of less than 3 cm small liver cancer,and 9 cases with 32 lesions of larger than 3 cm massive liver cancer were detected;43 lesions（89.6%） were showed off by hepatic arterial phase of CT,39 lesions （81.3%） were detected by portal phase,and 40 lesions（83.3%） were detected by delay phase,while 46 lesions（95.8%） were detected by hepatic arterial phase of MRI,and the detection rate of MRI portal phase was 52.1%,and the detection rate of the delay period was 85.4%,significantly different between CT and MRI detection （x²=14.376,P<0.05）;41 foci （85.4%） were detected by CT,and 44 （91.7%） were found out by MRI without significant difference between the two detection（x²=0.924,P>0.05）. Conclusion CT and MRI multi-phase dynamic contrast-enhanced scan can show enhanced features of liver cancer lesions,and there is no significant difference between CT and MRI scan.
