超声与多层螺旋CT在诊断急性胰腺炎中的应用比较

目的比较超声与多层螺旋CT在急性胰腺炎诊断中的应用价值。方法收集本院2013年3月至2016年4月收治的78例急性胰腺炎患者的临床资料，所有患者入院后均接受超声与多层螺旋CT检查，且影像学资料完整，比较超声及多层螺旋CT时急性胰腺炎的诊断价值。结果超声诊断急性胰腺炎总阳性率为51．28％，低于多层螺旋CT的80．77％，对比差异有统计学意义（P〈0．05）；超声对胰腺局部增大、胆总管结石、胰管扩张有较高的检出率，其检出胰管扩张、胆总管结石率高于多层螺旋CT（P〈0．05），多层螺旋CT对脂肪层模糊、胰腺局部增高、小灶液区有较高的捡出率，其中小灶液区检出率与超声比较差异有统计学意义（P〈0．05）。结论多层螺旋CT对急性胰腺炎整体检出率高，而超声对胆总管结石、胰管扩张显示率好，可作为有效的胰腺炎辅助诊断手段。

Objective To compare the application value of ultrasound and multi-slice spiral CT in the diagnosis of acute pancreatitis. Methods The clinical data of 78 patients with acute pancreatitis who were treated in our hospital from March 2013 to April 2016 were collected. All patients were examined by ultrasound and multi-slice spiral CT after admission, and the imaging data were complete. The value was compared between ukrasound and multi-slice spiral CT in the diagnosis of acute pancreatitis. Results The total positive rate of acute pancreatitis diagnosed by ultrasound （ 51.28% ） was lower than multi-slice spiral CT （ 80.77% ） （P〈0.05） . The detection rates of ultrasound for local pancreas enlargement, common bile duct stones and pancreatic duct dilation were high, and the detection rates of pancreatic duct dilatation and common bile duct stones were higher than multi-slice spiral CT （ P〈0.05 ） . The detection rates of multi-slice spiral CT for fuzzy fat layer, local pancreas were increased and small liquid region were high, and the detection rate ofsman liquid region showed a significant difference, compared with ultrasound （ P〈0.05 ） . Conclusion The detection rate of multi-slice spiral CT for acute pancreatitis is high, and display ofuhrasound for common bile duct stones and pancreatic duct dilatation is good. It can be used as an effective method for the diagnosis ofpancreatitis.
