目的探讨盆腔螺旋CT检查在小儿阑尾炎早期诊断中的应用价值。方法对34例小儿阑尾炎患者进行盆腔螺旋CT扫描,分别采用单纯轴位读取图像,以及多平面重建(MPR)这两种方法来读取CT图像,分别记为对照组和试验组。并于术后行病理检查。对比这两种方法诊断小儿阑尾炎的准确性。结果对照组方法诊断小儿阑尾炎的敏感性为59.25%,特异性为85.71%,阳性预测值为76.19%,阴性预测值为46.15%,准确性为64.7%;试验组诊断小儿阑尾炎的敏感性为77.78%,特异性为28.57%,阳性预测值为87.5%,阴性预测值为66.67%,准确性为67.65%。结论 MPR技术可以提高了小儿阑尾炎的术前正确诊断率。
Objective To investigate the value of pelvic spiral CT in early diagnosis of appendicitis in children. Methods Pelvic spiral CT was performed on 34 pediatric patients with appendicitis. CT images were read by simple axial reading images and multiplanar reconstruction (MPR), respectively, and were respectively recorded as control group and experimental group. And pathological examination after surgery. Comparison of these two methods to diagnose the accuracy of pediatric appendicitis. Results The sensitivity of the control group was 59.25%, the specificity was 85.71%, the positive predictive value was 76.19%, the negative predictive value was 46.15% and the accuracy was 64.7%. The sensitivity of the experimental group in diagnosing pediatric appendicitis was 77.78 %, The specificity was 28.57%, the positive predictive value was 87.5%, the negative predictive value was 66.67%, the accuracy was 67.65%. Conclusion MPR technique can improve the correct diagnosis of pediatric appendicitis.
