急性阑尾炎的多层螺旋CT评价

Value of multi - slice spiral CT in the diagnosis of acute appendicitis

目的探讨多层螺旋CT对阑尾炎的诊断价值。方法搜集手术和病理证实为阑尾炎者40例的临床资料，回顾性分析比较螺旋CT轴扫和多平面重建（MPR）、曲面重建（CPR）三种方法的诊断符合率。结果40例表现为阑尾增粗、壁增厚，其中16例阑尾内见结石、盲肠和（或）周围炎26例，脓肿12例。结论症状和体征不典型的阑尾炎临床诊断困难，易误诊，螺旋CT、MPR和CPR方法简单，可从不同角度观察病变部位及其周围情况，有利于鉴别诊断，提高诊断符合率，具有较高的临床价值。

Objective To explore the value of multi - slice CT with multi - planar reconstruction （MPR） and curved planar reconstruction（CPR） in diagnosis of appendicitis with atypical clinical features. Methods The accuracy of spiral CT with MPR and with axial scanning and with CPR of 40 cases of surgically and pathologically confirmed appendicitis were retrospectively compared. Results Swollen appendix and thick wall were observed in 40 cases and stone of 16 cases, and typhlitis of 26 cases, and abscess of 12 cases. Conclusions Spiral CT with MPR and CPR is higher sensitivity than that with axial scanning alone in diagnosis of appendicitis and shows higher clinical value.
