多层螺旋CT多平面重建在急性阑尾炎诊断中的应用

目的：探讨多层螺旋CT（MSCT）多平面重建（MPR）技术在急性阑尾炎诊断中的应用价值。方法：对76例疑似急性阑尾炎患者进行MSCT扫描,对扫描结果进行多平面重建,观察组根据轴位结合MPR像,对照组根据单纯轴位像做出的诊断结果并对结果进行对比。结果：与手术病理结果对比结果显示,单纯轴位像对急性阑尾炎诊断的敏感性、特异性、阳性预测值、阴性预测值及准确性分别为86.76%、37.50%、88.06%、25.00%、81.58%;轴位结合MPR像为98.53%、75.00%、91.10%、85.71%、96.05%。结论：MSCT应用MPR技术对临床疑似阑尾炎患者的诊断更具优势,提高了急性阑尾炎诊断的准确率及敏感性,值得临床推广应用。

Application of Multiplanar Reconstruction with MSCT to Diagnosis of Acute Appendicitis

Objective：Explore the applied value multilayer spiral CT（MSCT）multiplanar reconstruction（MPR）technique in the diagnosis of acute appendicitis.Methods：76 patients of clinical suspected acute appendicitis were taken scanning with MSCT,the date was analysis by workstation and obtained the results of axial images and axial combined with MPR images.Results：Compared with operation and pathology,the sensitivity,sensibility,positive predictive,negative predictive and accuracy in observation group were 98.53%,75.00%,91.10%,85.71% and 96.05% respectively.In the control group were 86.76%,37.50%,88.06%,25.00% and 81.58% respectively.Conclusion：MPR technique has more advantage in the diagnosis of suspected appendicitis,can improve the accuracy and sensitivity of the diagnosis,worthy of being widely applied in clinic.
