摘　　要：目的 探讨对于急性阑尾炎患者实施64层螺旋CT诊断的临床价值。方法 选取句容市人民医院在2018年1月—2022年4月期间收治的46例疑似急性阑尾炎患者,均进行超声及64层螺旋CT检查。分析比较两种检查方法的检出率及诊断准确率、误诊率以及漏诊率。结果 64层螺旋CT检查的敏感度、准确度分别为97.62%、91.30%,高于超声检查的敏感度、准确度57.14%、58.70%,差异有统计学意义(χ^(2)=19.657、13.043,P<0.05);在特异度、阳性预测值、阴性预测值方面,CT检查与超声检查比较差异无统计学意义(P>0.05)。结论 采取64层螺旋CT诊断急性阑尾炎的价值肯定,可以显示急性阑尾炎的影像特征,且可以更好地用于鉴别诊断,以在最大程度上减少误诊和漏诊的概率。Objective To explore the clinical value of implementing 64-layer spiral CT for the diagnosis of patients with acute appendicitis.Methods 46 patients with suspected acute appendicitis admitted to Jurong People´s Hospital from January 2018 to April 2022 were selected for ultrasound and 64-layer spiral CT examination.The detection rate and the diagnostic accuracy,misdiagnosis rate and leakage rate of acute appendicitis were analyzed and compared between the two examination methods.Results The sensitivity and accuracy of 64-layer spiral CT examination were 97.62%and 91.30%,respectively,which were higher than those of ultrasound,57.14%and 58.70%,and the difference was statistically significant(χ^(2)=19.657,13.043,P<0.05).There was no statistically significant difference in specificity,positive predictive value and negative predictive value between CT and ultrasonography(P>0.05).Conclusion The value of 64-layer spiral CT in the diagnosis of acute appendicitis is certain.It can display the imaging features of acute appendicitis and can be better used for differential diagnosis to minimize the probability of misdiagnosis and missed diagnosis.
