64层螺旋CT曲面重建及多平面重建技术对急性阑尾炎的诊断价值

The diagnostic value of 64-slice spiral CT multiplanar reconstruction and curved plannar reconstruction technique on acute appendicitis

目的:探讨64层螺旋CT多平面重建及曲面重建技术对急性阑尾炎的诊断价值。方法:回顾性分析60例行64层螺旋CT检查并经病理证实的急性阑尾炎病例。将常规扫描读片结合多平面重建、曲面重建的读片结果与常规横断位阅片结果进行对比分析,比较两者在诊断急性阑尾炎中的差异。结果:64层螺旋CT多平面重建及曲面重建联合应用阑尾显示率达到100%(60/60),阑尾外径增大、阑尾壁增厚的显示率也明显提高。结论:联合应用64层螺旋CT多平面重建及曲面重建可以更准确地识别阑尾,从而提高阑尾炎诊断的准确率。

Objective： To investigate the diagnostic value of 64-slice spiral CT multiplanar reconstruction （MPR） and curved planar reconstruction （CPR） on acute appendicitis. Method： 60 cases with acute appendicitis were analyzed retrospectively. All of them were verified by surgery and pathology underwent 64-slice spiral CT scanning by using multiplanar reconstruction （MPR） and curved planar reconstruction （CPR）. Compare the results and differences of reading the conventional axial scanning only and combined with MPR and CPR. Result：Satisfactory MPR and CPR images were obtained in 100% （60/60）of the cases. The discrimination rate of appendix and detection rate of appendiceal diameter and wall thickening were improved significantly. Conclusion： 64-slice spiral CT MPR and CPR technique could be used to accurately identify appendix and improve the accuracy of diagnosis of acute appendicitis.
