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.
