摘要
本文对增强CT与增强磁共振成像(CE-MRI)在肝细胞癌(HCC)病灶大小、血供评估方面进行对比研究。选取肝细胞癌患者102例112个病灶,比较增强CT、CE-MRI图像,采用卡方检验组间灵敏性、特异性等差异,Kappa检测两种方法的一致性。结果显示,增强CT和CE-MRI肝细胞癌病灶诊断灵敏性、特异性、准确率分别为90.29%和94.17%、88.89%和88.89%、90.18%和93.75%,比较差异无统计学意义(P>0.05);增强CT和CE-MRI测量病灶体积比较差异无统计学意义(P>0.05);在女性及男性患者间,增强CT和CE-MRI测量病灶体积比较差异无统计学意义(P>0.05);112个病灶中,增强CT和CE-MRI共同判断富血供病灶99个,乏血供病灶3个;增强CT和CE-MRI判断血供的一致性Kappa值为0.668,P<0.05;男女患者增强CT、CE-MRI判断血供情况比较差异无统计学意义(P>0.05)。增强CT与CE-MRI在肝细胞癌病灶大小、血供评估方面具有较好的一致性。
The purpose of this study was to explore the comparative study of contrast-enhanced CT and contrast-enhanced magnetic resonance imaging(CE-MRI)in the assessment of the size and blood supply of hepatocellular carcinoma(HCC),112 lesions of 102 patients with HCC were selected,the contrast-enhanced CT and CE-MRI images were compared,chi square test was used to test the differences in sensitivity and specificity between the groups,and Kappa was used to test the consistency of the two methods.The HCC diagnostic sensitivity,specificity and accuracy of enhanced CT and CE-MRI were 90.29%and 94.17%,88.89%and 88.89%,90.18%and 93.75%respectively,and the difference was not statistically significant(P>0.05).The lesions measured by contrast-enhanced CT and CE-MRI was not statistically significant(P>0.05).In female and male patients,there was no significant difference in the volume of lesions measured by contrast-enhanced CT and CE-MRI(P>0.05).Among 112 lesions,99 lesions with rich blood supply and 3 lesions with poor blood supply were determined by contrast-enhanced CT and CE-MRI.The consistency of Kappa value of blood supply was determined by contrast-enhanced CT and CE-MRI was 0.668,P<0.05.There was no significant difference in blood supply between male and female patients by contrast-enhanced CT and CE-MRI(P>0.05).Contrast-enhanced CT and CE-MRI showed good consistency in the size and blood supply assessment of HCC.
