摘　　要：目的探讨多层螺旋CT(MSCT)在阑尾炎中的诊断价值。方法回顾性分析本院2009年5月～2012年5月经手术和病理证实的81例阑尾炎患者的MSCT表现特点。结果 81例患者中,单纯急性阑尾炎35例,单纯慢性阑尾炎20例,合并阑尾周围脓肿26例。急性者主要表现为阑尾增粗肿大,壁增厚,边缘模糊,密度增高,部分患者阑尾腔内见粪石;慢性者可见阑尾外形不规则和粘连征象;合并阑尾周围脓肿者有中重度的周围炎性改变,可见脓肿和脓腔。结论 MSCT检查对阑尾炎的诊断具有重要价值,尤其是冠状位重建,能在术前了解阑尾位置,病变周围情况,并为临床术前准备提供参考。Objective To explore the value of MSCT in diagnosing of appendiciiis.-Methods MSCT manifestations of 81 cases with the appendicitis which were confirmed by surgery and pathology from May 2009 to May 2012 were ret- rospectively analyzed. Results Among 81 cases of patients,35 cases were simple acute appendicitis,20 cases were sim- ple chronic appendicitis,26 cases were periappendicural abscess.The CT findings of acute appendicitis mainly included enlargement,thickening of appendix wall,vague border, increased density,and calculus,which was visible sometimes.The appendix irregular appearance and adhesion signs were visible in chronic cases.There were moderate to severe inflam- matory change in the cases of appendicitis abscess with visible abscess and vonica. Conclusion The examination of MSCT has significant value for the diagnosis of appendicitis.Especially,the coronary reconstruction of MSCT can show the appendix location and the around changes of lesions before operation,and provide a reference for clinical preopera- tive preparation.
