ABSTRACT
Objective:To study the diagnostic value of MR diffusion weighted imaging (DWI) and CT and MR perfusion imaging in patients with different degrees of liver cirrhosis.Methods:A total of 60 patients with liver cirrhosis,who were treated in Ziyang Hospital of West China Hospital of Sichuan University from August 2015 to February 2017 were selected.According to the Child-Pugh classification,32 cases of grade A were mild cirrhosis (denoted as group A),16 cases of grade B and 12 cases of grade C were moderate to severe cirrhosis (denoted as group B),30 healthy volunteers were selected as group C in the same period.All the subjects in the three groups were examined by DWI,CT and MR perfusion imaging.The ADC value,hepatic portal perfusion ratio [SSr (CT) and SSr (MR)] were compared among the three groups,and Spearman correlation analysis was used to analyze the correlation between the indexes.Results:There was no significant difference in ADC values among the three groups (P>0.05),and the ADC values of group A and B were lower than those of group C,but the difference was not statistically significant (P>0.05).There was no significant difference in ADC values between group A and B (P>0.05).The levels of SSr (CT) and SSr (MR) in the three groups were compared,the difference was statistically significant (P<0.05);the levels of SSr (CT) and SSr (MR) in group B were significantly higher than those in group A and C,the difference was statistically significant (P<0.05).There was no significant difference in the levels of SSr (CT) and SSr (MR) in group A and C (P>0.05).Spearman correlation analysis showed that SSr (CT) was positively correlated with SSr (MR) in the patients with liver cirrhosis (r=0.687,P=0.000).Conclusion:CT and MR perfusion imaging can reflect the lesion degree of liver cirrhosis,and diagnostic effects of the two are better than DWI imaging,which is worthy of clinical promotion.
