【摘要】Objective To study the diagnostic role of low - dose spiral CT with

multiplanar

reconstruction

in

atypical

pediatric

acute

appendicitis.Methods Forty-five pediatric patients diagnosed with suspected acute appendicitis due to atyical symptoms were retrospectively reviewed.The radiological outcomes were compared against surgical and pathological results.Results Low-dose CT with multiplanar reconstruction identified two false positive cases out of 30 patients diagnosed with acute appendicitis.In the remainder 15 patients diagnosed without acute appendicitis, one turned out to be false negative.The accuracy was 93.33 ％ , sensitivity 96.55 ％ ,and specificity 87.50％.Conclusion Low-dose CT with multiplanar reconstruction is an effective diagnostic tool for atypical pediatric acute appendicitis ,with a high accuracy, sensitivity, specificity, and clinical usefulness.%目的 探讨低剂量螺旋CT多平面重建对儿童不典型急性阑尾炎的诊断价值.方法 回顾性分析临床症状不典型、疑诊为儿童急性阑尾炎的45例患者的病历,将低剂量螺旋CT多平面重建的诊断结果与手术、病理结果进行比较.结果 采用低剂量螺旋CT多平面重建图像分析,30例诊断为急性阑尾炎的患儿中,有2例假阳性,15例诊断为非急性阑尾炎的患儿中,有1例是假阴性;其准确度为93.33%,敏感度为
