【摘要】目的探讨非增强螺旋CT多平面重组技术在急性阑尾炎诊断中的应用价值。方法对17例临床疑是急性阑尾炎的急诊患者行螺旋CT常规平扫检查,全部病例扫描完成后均于工作站上进行多平面重组(MPR)。术后11例确诊为急性阑尾炎. 结果对照手术病理结果,%,%,%,%,%;%,%,%,%,%。本组病例主要的CT表现有阑尾增粗(6例),阑尾结石(6例), 阑尾周围炎性改变(3例), 蜂窝织炎(7例), 阑尾脓肿(3例), 盲肠、邻近小肠末端肠壁增厚(6例)。结论 MPR技术能快速准确地显示阑尾及其周围组织的改变,明显提高了非增强螺旋CT诊断急性阑尾炎的准确性,对临床治疗方案的制定有很大帮助。

[Abstract] Objective To investigate the applied value of multiplanar reformation (MPR) with unenhanced MSCT in diagnosing acute appendicitis. Methods 17 patients with clinically suspected acute appendicit is performed conventional CT scanning and MPR before the surgery. Appendicitis was confirmed in 11 cases after the operation. pared with the surgery and pathological results, MPR provided a diagnostic accuracy of %, sensitivity of %, specificity of %, positive predictive value of % and negative predictive value of %. In contrast, conventional CT scanning yielded an accuracy of %, sensitivity of %, specificity of %, positive predictive value of % and negative predictive value of %.The mon CT findings of acute appendicitis were an enlarged appendix 6 cases ,appendolith 6 cases,periappendicular inflammatory changes 3 cases, phlegmonous inflammation 7 cases,appendicular abscess 3 c
