摘　　要：目的探讨螺旋CT薄层重建图像快速诊断急性阑尾炎的价值。方法对139例急腹症患者行腹部螺旋CT常规平扫,然后进行1.30 mm薄层重建,采用轴位连续动态观察,将诊断结果与手术及病理结果进行对照,并总结其CT表现。结果 139例患者中,CT明确诊断阑尾炎32例,可疑诊断5例,经手术病理证实35例,2例误诊,另有3例为假阴性,CT诊断符合率为94.6%(35/37),漏诊率为0.2%(3/139)。结论急性阑尾炎多层螺旋CT扫描通过薄层重建图像可获得真实可靠的信息,并能快速作出准确诊断,减少误诊、漏诊。Objective To explore the thin-slice reconstruction of spiral CT in the diagnostic value of acute ap- pendicitis. Methods One hundred and thirty-nine patients of acute abdomen undergo abdominal muhilayer spiral CT scanning, and the thin-layer reconstruction with thickness of 1.30 ram, adopted continuous dynamic observation of the axis images. The CT images were retrospectively analyzed and correlated with surgery and pathology findings. Results Of the 139 patients, there were acute appendicitis in 32 patients CT diagnosis displayed, the surgical pathology con- finned 35 eases were positive,2 cases were misdiagnosed, 3 cases were false-negative. The diagnosis coincidence rate was 94.6% （35/37）,the false negative rate was 0.2% （3/139）. Conclusion The multilayer spiral CT scanning for clinical acute appendicitis could gain valuable and true information, and could rapidly make correct diagnosis, reduce the erroneous diagnosis or missed diagnosis.
