多层螺旋CT对急性阑尾炎诊断的临床价值

Clinical value of multi-slice spiral CT in the diagnosis of acute appendicitis

目的探讨多层螺旋CT(MSCT)在急性阑尾炎诊断中的临床价值。方法回顾我院收治的51例经病理诊断为急性阑尾炎患者的MSCT扫描结果和超声检查结果,对比两种方法在急性阑尾炎诊断中的影像学表现及对急性阑尾炎的检出率。结果MSCT对阑尾增粗肿大、阑尾壁充血增厚及阑尾周围炎症的检出率均高于超声检查(P<0.05);MSCT对阑尾脓肿或炎性包块形成的检出率与超声检查比较无显著差异(P>0.05);MSCT对急性阑尾炎的总检出率高于超声检查(P<0.05)。结论 MSCT具有空间分辨率高、成像质量好等特点,可以提高疾病的检出率,在急性阑尾炎的诊断中具有指导意义,值得临床推广与应用。

Objective To investigate the clinical value of multi -slice spiral CT （MSCT）in the diagnosis of acuteappendicitis. Methods The results of MSCT and ultrasonography in 51 patients with acute appendicitis diagnosed bypathology were reviewed. The imaging performance and detection rate of acute appendicitis in the diagnosis of acuteappendicitis by the two methods were compared. Results The detection rates of appendix enlargement, appendix wallcongestion and periappendiceal inflammation by MSCT were higher than thaose by ultrasonography（P〈0.05）; the detection rateof appendiceal abscess or inflammatory mass by MSCT was not significantly different from that by ultrasonography（P〉0.05）.The total detection rate of MSCT for acute appendicitis was higher than that by ultrasonography （P〈0.05）. ConclusionMSCT has the characteristics of high spatial resolution and good imaging quality. It can improve the detection rate ofdiseases. It has guiding significance in the diagnosis of acute appendicitis and is worthy of clinical promotion and application.
