目的比较多层螺旋CT(MSCT)与 超声对急性阑尾炎的诊断价值。方法 以 我院2013年1月-2015年6月经手术病理证 实的60例急性阑尾炎患者为研究对象，术 前均分别行超声、腹部多层螺旋CT检查， 观察分析两者图像特征，并与手术病理 结果对照。结果 与手术病理结果对照， MSCT对急性单纯性阑尾炎、急性化脓性 阑尾炎、，急性坏疽性阑尾炎诊断相符 率分别为78.6%、100.0%、100.0%；超声 对急性单纯性阑尾炎、急性化脓性阑尾 炎、急性坏疽性阑尾炎诊断相符率分别为 57.1%、85.2%、100.0%。MSCT对急性化脓 性阑尾炎诊断相符率明显高于超声检查， 差异有统计学意义(P＜0.05)。结论 相比 超声，多层螺旋CT对急性阑尾炎诊断符合 率更高，特别是急性化脓性阑尾炎。

Objective To compare the diagnostic value of multi-slice spiral CT (MSCT) and ultrasound in acute appendicitis. Methods 60 cases of patients with acute appendicitis confirmed by surgery and histopathology who were admitted into the hospital during January 2013 to June 2015 were selected as the research objects. Ultrasound and abdominal multi-slice spiral CT were performed before surgery. The image features of the two were observed and analyzed. The results were compared with surgical and pathological findings. Results Compared with surgical and pathological findings, the accordant rates of MSCT in the diagnosis of acute simplex appendicitis, acute purulent appendicitis and acute gangrenous appendicitis were 78.6%, 100.0% and 100.0% while of ultrasound were 57.1%, 85.2% and 100.0%. The diagnostic accordant rate of MSCT in acute suppurative appendicitis was significantly higher than that of ultrasound and the difference was statistically significant (P<0.05). Conclusion Compared with ultrasound, the diagnostic accordant rate of MSCT in acute appendicitis is higher, especially in acute suppurative appendicitis.
