摘　　要：目的研究磁共振成像+增强CT在急性胰腺炎患者中的诊断价值。方法选择我院2020年4月至2021年5月纳入的疑似急性胰腺炎患者127例,收集并整理所有患者齐全资料,分别开展磁共振成像以及增强CT检查,将临床最后诊断结果作为“金标准”,观察磁共振成像以及增强CT检查的影像学表现,对比磁共振成像结果(A组)、增强CT结果(B组)与联合检查(C组)的准确度、灵敏度、特异度。结果A组中95例轻度患者的T_(1)、T_(2)信号略长,边缘不清楚;而22例重度患者T_(1)信号混杂长,T_(2)信号混杂。而B组中90例轻度患者胰腺体积扩大,均匀强化,边缘毛躁;而20例重度患者胰腺体积明显扩大,形态无规则,胰腺均匀强化,存在低密度液化区以及高密度出血灶。C组的准确度、灵敏度、特异度均高出A组、B组(P<0.05)。A组与C组面积之间差异是0.354,标准误差0.081,Z统计4.395,P<0.05;B组与C组面积之间差异是0.347,标准误差0.093,Z统计3.747,P<0.05,两组的诊断价值存在的差异。结论磁共振成像+增强CT在诊断急性胰腺炎上准确性更高,同时可观察到患者病情的严重程度,值得推广。Objective To study the diagnostic value of magnetic resonance imaging+enhanced CT in patients with acute pancreatitis.Methods 127 patients with suspected acute pancreatitis included in our hospital from April 2020 to May 2021 were selected.Complete data of all patients were collected and sorted out.Magnetic resonance imaging and enhanced CT were carried out respectively.The final clinical diagnostic results were taken as the gold standard.The imaging manifestations of magnetic resonance imaging and enhanced CT were observed and compared(group A)The accuracy,sensitivity and specificity of enhanced CT results(group B)and combined examination(Group C).Results In group A,the T_(1) and T_(2) signals of 95 mild patients were slightly longer and the edge was unclear;In 22 severe patients,T_(1) signal was long and T_(2) signal was mixed.In group B,90 patients with mild pancreatic volume expansion,uniform enhancement and edge irritability;In 20 severe patients,the pancreatic volume was significantly expanded,the shape was irregular,the pancreas was uniformly strengthened,and there were low-density liquefied areas and high-density bleeding foci.The accuracy,sensitivity and specificity of group C were higher than those of group A and group B(P<0.05).The area difference between group A and group C was 0.354,standard error 0.081,Z statistics 4.395,P<0.05;The area difference between group B and group C was 0.347,the standard error was 0.093,Z statistics was 3.747,P<0.05.Conclusion MRI+enhanced CT is more accurate in the diagnosis of acute pancreatitis,and can observe the severity of the patient's condition,which is worthy of popularization.
