The purpose of this study was to assess the feasibility of diagnosing appendicitis based on coronal reformations without the aid of transverse images. Abdominal and pelvic computed tomography (CT) scans of 53 patients (27 with appendicitis and 26 without appendicitis) were reviewed. All scans were obtained using a four-slice multi-detector row CT. The radiologists were not aware of the final diagnosis. Cases were reviewed for the visualization of the appendix and presence of appendicitis. All images were reviewed on picture archiving and communication systems. There were no false positives for diagnosing appendicitis when using either the transverse or coronal reformations. Appendicitis was not seen on the coronal images in one case, and there were no false negatives when transverse reformations alone were used. This difference was not statistically significant (p < 0.0001 for both modes of display). The sensitivity for diagnosing appendicitis based on the coronal images alone was 96%, the specificity was 100%, and the accuracy was 98%. Coronal reformations decreased the number of images reviewed by 19%. CT diagnosis of appendicitis based on the coronal images is accurate.
本研究的目的是评估在不借助横断面图像的情况下基于冠状位重建诊断阑尾炎的可行性。回顾了53例患者（27例患有阑尾炎，26例未患阑尾炎）的腹部和盆腔计算机断层扫描（CT）图像。所有扫描均使用四排多层探测器CT进行。放射科医生不知最终诊断结果。对病例进行阑尾可视化及阑尾炎存在情况的评估。所有图像均在图像存档与通信系统上进行查看。使用横断面或冠状位重建诊断阑尾炎时均无假阳性。有1例在冠状位图像上未发现阑尾炎，仅使用横断面重建时无假阴性。这种差异无统计学意义（两种显示模式的p值均<0.0001）。仅基于冠状位图像诊断阑尾炎的敏感性为96%，特异性为100%，准确性为98%。冠状位重建使查看的图像数量减少了19%。基于冠状位图像的CT诊断阑尾炎是准确的。
