目的:探讨增强CT与磁共振成像在急性胰腺炎合并肝损伤的诊断效果。方法:收集2012年6月至2014年6月来我院就诊的急性胰腺炎合并肝损伤疑似病例180例,分别行增强CT和MRI检查,判断两者诊断效果差异。结果:MRI检查灵敏度、阳性似然比和阴性似然比高于增强CT检查,经卡方检验,差异均有统计学意义(P<0.05),而两者灵敏度经卡方检验均无统计学差异(P>0.05)。结论:磁共振成像诊断急性胰腺炎合并肝损伤具有更精确的诊断效果,但增强CT诊断特异度不亚于磁共振检查,可用作初步筛查诊断。
Objective: To investigate the diagnostic value of enhanced CT and magnetic resonance imaging in acute pancreatitis complicated with liver injury. Methods: A total of 180 suspected cases of acute pancreatitis and liver damage were collected from June 2012 to June 2014 in our hospital. CT and MRI were performed to evaluate the difference in diagnosis between the two groups. Results: The MRI examination sensitivity, positive likelihood ratio and negative likelihood ratio were higher than those of enhanced CT examination. The differences were statistically significant (P <0.05) by chi-square test. There was no statistical difference between the two methods in sensitivity Difference (P> 0.05). Conclusion: Magnetic resonance imaging can diagnose acute pancreatitis with liver injury more accurately. However, the specificity of enhanced CT diagnosis is no less than that of magnetic resonance imaging. It can be used as a preliminary screening diagnosis.
