[摘 要]目的: 探讨多层螺旋CT(MSCT)在非创伤性急腹症病因中的诊断价值。方法: 对63例临床拟诊为急腹 症患者的术前MSCT、B超、腹部平片等影像学资料进行对比分析。 结果: MSCT在非创伤性急腹症的病因诊断中有较 高的准确率。术前诊断的准确率分别为MSCT 90.5%、超声42.6%、腹部平片26.8%。经χ2检验，χ2=231.04，P <0.01， 具有统计学上的差异。 结论: MSCT对急腹症的早期病因诊断具有重要的临床价值，它能使急腹症患者得到及 时、准确、有效的治疗，可作为急腹症患者的首选检查方法。

    [Abstract] Objective: To discuss the value of multi-slice spiral CT(MSCT) in diagnosis of untraumatic acute abdominal disease. Methods: In 63 patients with acute abdominal disease diagnosed by clinic，their pre-operative results of MSCT，B-ultrasound and X-ray were analysed in contrast. Results: MSCT has a higher accuracy to diagnose the acute abdomen. The diagnostic accuracy was 90.4% in MSCT，42.6% in B-ultrasound，26.7% in X-ray. They had statistical difference(χ2=231.04 ......
