目的研究16层螺旋CT对急性阑尾炎的诊断价值。方法对经临床确诊的58例急性阑尾炎的CT表现进行回顾性分析,行最大密度投影(MIP)、曲面重建(CPR)后处理技术对阑尾大小、形态及盲肠周围改变进行观察分析。结果58例中有56例多层螺旋CT诊断正确。其中急性阑尾炎24例(42.86%),急性阑尾炎并阑尾周围炎25例(44.64%),阑尾脓肿6例(10.71%),炎性肿块1例(1.79%)。直接征象为阑尾增粗增大(直径6mm)、阑尾结石,间接征象包括阑尾周围炎、阑尾周围脓肿或炎性肿块、盲肠末端肠壁增厚和局部淋巴结肿大等。结论16层螺旋CT检查能快速、准确地诊断急性阑尾炎,并能发现除阑尾炎以外的各种病变。
Objective To study the diagnostic value of 16-slice spiral CT in acute appendicitis. Methods The CT findings of 58 cases of clinically diagnosed acute appendicitis were analyzed retrospectively. The size and shape of the appendix and the changes around the cecum were observed and analyzed by MIP and CPR postprocessing. Results Fifty-eight of 58 cases were correctly diagnosed by multi-slice spiral CT. There were 24 cases (42.86%) with acute appendicitis, 25 cases (44.64%) with acute appendicitis and appendicitis, 6 cases with appendix abscess (10.71%) and 1 case with inflammatory mass (1.79%). Direct signs of increased appendiceal enlargement (diameter 6mm), appendix stones, indirect signs of inflammation around the appendix, abscess or inflammatory mass around the appendix, end of the cecal thickening of the intestinal wall and local lymph nodes. Conclusion 16-slice spiral CT can quickly and accurately diagnose acute appendicitis, and can find various lesions except appendicitis.
