摘    要: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96.55%,特异度为87.50%。结论低剂量螺旋CT多平面重建技术能为儿童不典型急性阑尾炎的诊断提供有力依据,其准确性高,敏感性和特异性强,具有较高的临床价值。

关 键 词:阑尾炎  低剂量  X线计算机体层摄影术  多平面重建  诊断  儿童

Abstract: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...
