多层螺旋CT对急性阑尾炎的诊断

The diagnosis of acute appendicitis with MSCT

目的:分析多层螺旋CT(Multislice CT,MSCT)对急性阑尾炎的诊断。方法:对67例手术、病理证实为急性阑尾炎的腹部多层螺旋CT资料进行回顾性分析,对阑尾大小、形态及盲肠周围改变进行观察、分析。结果:67例中有64例多层螺旋CT诊断正确,CT表现包括直接征象和间接征象。直接征象为阑尾增粗增大(82.08%),间接征象包括阑尾盲肠周围炎(73.13%),阑尾周围脓肿(11.94%)。有3例急性阑尾炎患者CT无明显异常征像。结论:MSCT征象对急性阑尾炎的诊断有很大帮助。

Objective：To analyse the diagnostic of multislice CT（MSCT）for acute appendicitis.Methods：Sixty-seven patients with acute appendicitis confirmed by surgery and histopathology were analyzed retrospectively.The sizes of appendixes,appendolith,periappendiceal changes were observed and noted.Results：Sixty-four of the sixty-seven patients were correctly diagnosed as acute appendicitis.The direct CT signs of acute appendicitis were an enlarged appendix（82.08%）.Indirect signs includedappeniceal perityphlitis（73.13%） and preiappendicular abscess（11.94%）;and three cases were not observed with CT.Conclusion：Acute appendicitis has a variety of CT signs which is helpful to improve the diagnosis.
