目的探讨16层螺旋CT重组技术在诊断急性阑尾炎中的应用价值。方法回顾性分析50例临床拟诊为急性阑尾炎而行16层螺旋CT检查和重组技术多平面重组(MPR)及曲面重组(CPR)的病例资料。结果45例经手术病理证实为急性阑尾炎,CT诊断急性阑尾炎41例,91.1%(41/45)成功获得重组技术多平面重组及曲面重组图像。应用16层螺旋CT重组技术后,提高了阑尾系膜水肿、回盲肠壁水肿的显示率及阑尾识别率。结论16层螺旋CT重组技术可以准确地识别阑尾,能快速、准确地诊断急性阑尾炎,并能发现除阑尾炎以外的病变。
Objective To investigate the value of 16-slice spiral CT in the diagnosis of acute appendicitis. Methods A retrospective analysis of 50 cases of clinically diagnosed as acute appendicitis with 16-slice spiral CT examination and reconstruction of multiplanar reorganization (MPR) and surface reconstruction (CPR) cases. Results 45 cases were proved to be acute appendicitis by operation and pathology. CT was used to diagnose 41 cases of acute appendicitis, and 91.1% (41/45) were successfully obtained multi-planar and curved surface reconstruction images. The application of 16-slice spiral CT reconstruction technique improved the appendix mesangial edema, ileocecal intestinal edema and appendix recognition rate. Conclusion The 16-slice spiral CT reconstruction technique can accurately identify the appendix, quickly and accurately diagnose acute appendicitis, and can detect lesions other than appendicitis.
