摘要
目的探讨MSCT扫描及其图像重组技术对急性阑尾炎术前定位、定性诊断的临床应用价值。方法回顾性分析100例经手术证实的急性阑尾炎患者和100例无阑尾病变者的全腹部螺旋CT及多平面重组图像表现,重点观察阑尾的位置、直径、阑尾壁的厚度、内容物及阑尾周围结构的改变,并进行对比研究。结果急性阑尾炎组阑尾显示率91%(91/100),正常阑尾组阑尾显示率82%(82/100)。急性阑尾炎组和正常阑尾组阑尾位置分布的差异无统计学意义(P>0.05)。急性阑尾炎组和正常阑尾组阑尾直径、阑尾壁厚度的差异均有统计学意义(P<0.01)。急性阑尾炎的MSCT征象:阑尾增粗,腔内粪石、积气,周围渗出性腹膜炎,脓肿形成的出现率分别为88%(88/100)、22%(22/100)、18%(18/100)、62%(62/100)、14%(14/100)。结论 MSCT能够定位、定性诊断急性阑尾炎,为手术方案的制定提供有力证据。
Objective To explore the value of non-enhanced helical CT scanning and reconstruction in diagnosis of acute appendicitis preoperatively for the location and qualitation. Materials and Methods The imaging data including CT and reconstruction images of 100 patients with acute appendicitis confirmed by surgery and 100 patients without acute appendicitis were retrospectively analyzed. The study appearance includes the location, diameter, wall thickness, content of appendix and structure around the appendix. Results Among 100 patients with acute appendicitis, the appendix ware detected in 91 cases. Among 100 cases without acute appendicitis, the appendix were detected in 82 cases. The distribution of appendix in 2 groups showed no difference by statistically significant（P〉0.05）. The diameter, wall thickness of appendix in 2 groups showed difference by statistically significant（P 〈 0.01）. The MSCT appearances of acute appendicitis includes enlarged appendix（88%）, the fecalith（22%） and air（18%） in appendix, periappendicnlar exudative peritonitis （52%） and periappendicular abscess（14%）. Conclusion MSCT is of significant value in diagnosis of acute appendicitis including the location and qualitation. It is helpful for the evidence of operative proposal.
