摘　　要：目的探究磁共振成像与多层螺旋CT在疑似急性胰腺炎诊断中的应用价值。方法选取2019年1月至2023年2月于抚州市东信第六医院就诊的82例疑似急性胰腺炎患者作为研究对象。所有患者均行磁共振成像与多层螺旋CT检查,观察两种检查方法的影像学征象,并以临床最终诊断结果为金标准,比较两种检查方法的诊断灵敏度、特异度及准确度。结果82例疑似急性胰腺炎患者经临床最终诊断为急性胰腺炎74例,非急性胰腺炎8例。磁共振成像诊断为急性胰腺炎75例,非急性胰腺炎7例,66.67%明显胰腺肿大,20.00%胰腺肿大,17.33%胰周积液,60.00%胰周、胰腺长T1、T2信号;诊断灵敏度、特异度及准确度分别为98.65%、75.55%及96.34%。多层螺旋CT诊断为急性胰腺炎60例,非急性胰腺炎22例,66.67%胰腺肿大、密度均匀、形态规则,20.00%边缘模糊不清,16.67%边缘清晰,40.00%胰腺内密度不均、胰腺体积增大、不规则或斑片状低密度影,8.33%胰腺坏死及脓肿;诊断灵敏度、特异度及准确度分别为79.73%、87.50%及80.49%。磁共振成像诊断急性胰腺炎的灵敏度、准确度均高于多层螺旋CT,差异有统计学意义(P<0.05)。结论磁共振成像与多层螺旋CT对急性胰腺炎诊断均有一定价值,但前者诊断灵敏度、准确度更高。Objective To explore the application value of magnetic resonance imaging and multislice spiral CT in the diagnosis of suspected acute pancreatitis.Methods A total of 82 patients with suspected acute pancreatitis were treated in the Fuzhou Dongxin Sixth Hospital from January 2019 to February 2023 were selected as the study subjects.All the patients underwent magnetic resonance imaging and multislice spiral CT examination,the imaging signs of two examination methods were observed,took the final diagnosis results as the gold standard,the diagnosis sensitivity,specificity and accuracy were compared between the two examination methods.Results 82 patients with suspected acute pancreatitis were finally diagnosed as acute pancreatitis in 74 cases and non-acute pancreatitis in 8 cases.Magnetic resonance imaging diagnosed 75 cases of acute pancreatitis and 7 cases of non-acute pancreatitis,with 66.67%obvious pancreatic enlargement,20.00%pancreatic enlargement,17.33%peripancreatic effusion,60.00%peripancreatic and long T1 and T2 signals;diagnostic sensitivity,specificity and accuracy were 98.65%,75.55%and 96.34%,respectively.Multislice spiral CT diagnosed 60 cases of acute pancreatitis and 22 cases of non-acute pancreatitis,with 66.67%pancreatic enlargement,uniform density,regular morphology,20.00%with blurred margin,16.67%clear margin,40.00%uneven pancreatic density,increased pancreatic volume,irregular or patchy low density,8.33%pancreatic necrosis and abscess;diagnostic sensitivity,specificity and accuracy were 79.73%,87.50%and 80.49%,respectively.The diagnostic sensitivity and accuracy of acute pancreatitis by magnetic resonance imaging were higher than those of multislice CT,and the differences were statistically significant(P<0.05).Conclusion Magnetic resonance imaging and multislice spiral CT have some value in the diagnosis of acute pancreatitis,but the former has higher diagnostic sensitivity and accuracy.
