【摘要】：目的探究磁共振成像(MRI)对感染性胰腺炎合并肝脏损伤患者的诊断价值,为临床治疗提供参考依据。方法选取2015年2月-2016年6月医院收治的感染性胰腺炎合并肝损伤疑似病例162例,所有患者均进行CT和MRI检查,观察两种检查方法的检查结果,分析两种检查方法的阳性率、诊断灵敏度、特异度等。结果 CT检查结果显示真阳性结果120例,真阴性15例,假阳性3例,假阴性24例;MRI检查结果显示真阳性结果135例,真阴性21例,假阳性2例,假阴性4例;CT的阳性率、阴性率、灵敏度、特异度、阳性似然比、阴性似然比为75.93%、24.07%、97.56%、83.33%、5.85%、0.03%;MRI为84.57%、15.43%、98.54%、91.30%、11.326%、0.016%;MRI检查阳性率与病理检查阳性率间差异无统计学意义,而CT检查阳性率与病理检查阳性率间差异有统计学意义(P0.05)。结论 MRI用于诊断急性胰腺炎合并肝脏损伤时具有更好的特异度,能够做到精确诊断,可做为临床上诊断急性胰腺炎合并肝脏损伤的重要依据。
[Abstract]:Objective to investigate the diagnostic value of magnetic resonance imaging (MRI) in patients with infectious pancreatitis complicated with liver injury. Methods A total of 162 suspected cases of infectious pancreatitis complicated with liver injury were selected from February 2015 to June 2016. All the patients were examined by CT and MRI, and the results of the two methods were observed. Results the results of CT showed that 120 cases were true positive, 15 cases were true negative, 3 cases were false positive and 135 cases were false negative. The positive rate, negative rate, sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of CT in 21 cases of true negative, 2 cases of false positive and 4 cases of false negative were 75.933%, 24.07%, 24.07% and 83.33% respectively, and the MRI was 84.57%, 15.4398.54%, 91.30%, 11.3266% and 0.016% respectively. There was no significant difference between the positive rate of MRI and the positive rate of pathological examination. There was significant difference between the positive rate of CT and the positive rate of pathological examination. Conclusion MRI has better specificity in the diagnosis of acute pancreatitis with liver injury and can be accurately diagnosed. It can be used as an important basis for clinical diagnosis of acute pancreatitis with liver injury.
