摘要
目的探讨64层CT多平面重组(MPR)对急性阑尾炎的影像学特征及诊断价值。方法收集天津市武清区人民医院外科怀疑急性阑尾炎患者87例,所有患者均行CT平扫检查,将图像带至工作站进行MPR重建,从多方位进行观察。所有患者均行外科手术治疗,并有术后病理结果。结果 87例患者中,在CT平扫结合MPR下诊断急性阑尾炎患者共65例,其中单纯急性阑尾炎22例,阑尾炎伴阑尾粪石34例,阑尾炎伴阑尾穿孔2例,阑尾炎伴阑尾周围脓肿7例。另8例单纯性阑尾炎术前CT未做出明确诊断,后经手术病理证实。CT平扫结合MPR对急性阑尾炎诊断的敏感度、特异度、阳性预测值、阴性预测值分别为89.0%、100.0%、100.0%、63.6%。结论 64层CT的MPR重建对急性阑尾炎的诊断、严重程度判断有重要的诊断价值,尤其是MPR冠状位重建。
Objective To investigate the imaging features and diagnostic value of 64-slices CT multiplanar reconstruction(MPR)in acute appendicitis.Methods 87 patients with suspected acute appendicitis in the surgical department of Tianjin Wuqing District People’s Hospital were collected.All patients underwent CT plain scan.The images were taken to the workstation for MPR reconstruction and observed from multiple directions.All patients underwent surgical treatment and had postoperative pathological results.Results Among the 87 patients,65 cases were diagnosed as acute appendicitis by CT plain scan combined with MPR,including 22 cases of simple acute appendicitis,34 cases of appendicitis with appendicitis fecal stone,2 cases of appendicitis with appendicitis perforation,and 7 cases of appendicitis with periappendiceal abscess.The other 8 cases of simple appendicitis were not diagnosed by CT before operation,and confirmed by operation and pathology.The sensitivity,specificity,positive predictive value and negative predictive value of CT plain scan combined with MPR in the diagnosis of acute appendicitis were 89.0%,100.0%,100.0%and 63.6%,respectively.Conclusion The MPR of 64-slice spiral CT has important value in the diagnosis and severity judgment of acute appendicitis,especially the coronal MPR.
