目的 探讨多层螺旋CT对结肠憩 室炎的诊断价值。方法 对53例经内镜、 手术证实为结肠憩室炎患者的术前全腹多 层螺旋CT征象进行回顾性分析，并以内 镜、手术结果为标准，评价CT诊断的准确 性，并对评估失误病例进行分析、总结。 结果 53例患者中，发现结肠憩室53例， 憩室壁增厚50例，邻近结肠壁增厚48例， 结肠周围炎性改变53例，肠袢间或肠系膜 周围积液10例，腹腔游离气体5例，腹腔 脓肿3例，肠梗阻2例，多层螺旋CT诊断的 准确率为94.3％。结论 多层螺旋CT螺旋 能准确地诊断结肠憩室炎，对临床治疗方 案的选择有重要的临床价值。

Objective To investigate the diagnostic value of the multi-slice CT(MSCT) in colonic diverticulitis. Methods Whole abdominal MSCT scanning was performed in 53 cases of colonic diverticulitis that were confirmed by endoscope or operation．The CT signs were retrospectively analyzed and were evaluated in accordance with clinical or operative pathologic results. Results Of the 53 cases, colonic diverticula(n=53), diverticula wall thickening(n=50), localized colonic bowel wall thickening(n=48), pericolonic inflammatory evidence(n=53), surrounding bowel and mesenteric fluid(n=10), intraperitoneal or retroperitoneal free air(n=5), pericolic abscess(n=3), intestinal obstruction(n=2).The diagnostic compatibility rate of MSCT was 94.3%. Conclusion MSCT is very useful in the diagnosis of colonic diverticulitis, and has important clinical value for the choice of clinical treatment plan.
