摘要
目的:探讨和对比超声和多层螺旋CT(MSCT)对可疑急性阑尾炎患者的临床诊断价值。方法:对我院急诊科收治的335例可疑阑尾炎的患者进行超声和MSCT检查,并与手术病理结果对照,比较2种影像学检查技术的临床诊断价值。结果:MSCT诊断急性阑尾炎的敏感性和阴性预测价值明显高于超声检查(98.0%vs.85.2%,93.8%vs.66.4%,P<0.01);MSCT诊断急性阑尾炎阑尾穿孔的敏感性优于超声检查(91.2%vs.67.6%,P<0.05)。超声在检测阑尾增粗肿大和阑尾壁充血增厚的敏感性明显低于MSCT(P<0.01),且在检测阑尾-盲肠周围炎和阑尾周围脓肿时的敏感性和特异性均明显低于MSCT(P<0.01)。结论:多层螺旋CT诊断急性阑尾炎的发生、阑尾穿孔和多种影像学征象的诊断价值明显优于超声检测。
Objective：To investigate the diagnostic values of ultrasound and multi-slice computer tomography（MSCT）in patients with suspicious acute appendicitis.Method：Three hundred and thirty-five patients with suspicious acute appendicitis were recruited for ultrasound and MSCT evaluations.Data from ultrasound and MSCT were compared.The definitive diagnoses were made by surgical and pathological findings.Diagnostic values of both radiological modalities were determined and compared.Result：MSCT had a higher sensitivity and negative predictive value than ultrasound in diagnosing the occurrence of acute appendicitis（sensitivities 98.0% vs.85.2%,negative predictive values 93.8% vs.66.4%,P〈0.01）.MSCT had a higher sensitivity than ultrasound in diagnosing perforated appendicitis（sensitivities 91.2% vs.67.6%,P〈0.05）.When examining enlarged appendix and congestion of appendix wall,the sensitivity of ultrasound was much less than MSCT（P〈0.01）,and when examining inflammation around appendix-cecum and periappendiceal abscess,the sensitivity and specificity of ultrasound were significantly lower than MSCT（P〈0.01）.Conclusion：MSCT had better diagnostic performances in diagnosing the occurrence of appendicitis,perforation,and various radiological signs of appendicitis than ultrasound.
