急性阑尾炎应用不同剂量腹部增强CT诊断比较分析

Comparative Analysis of the Diagnosis of Acute Appendicitis Application on Different Doses of Abdominal Enhanced CT

目的比较分析急性阑尾炎应用不同剂量腹部增强CT的临床诊断。方法选择2013年5月～2015年5月我院收治的72例急性阑尾炎患者作为研究对象,随机将患者分成对照组与观察组,每组36例。观察组给予低剂量腹部增强CT扫描,对照组给予常规剂量腹部增强CT扫描,对比两组患者诊断效果与受照射剂量。结果观察组扫描剂量（9.1±3.1）m Gy,有效毫安秒（79±24）m As,对照组扫描剂量（23.5±6.3）m Gy,有效毫安秒（195±45）m As,观察组扫描剂量与有效毫安秒低于对照组,两组对比差异显著（P〈0.05）;两组CT诊断结果无明显差异（P〉0.05）。结论急性阑尾炎应用低剂量腹部增强CT扫描不会影响诊断价值,同时,还能降低患者的受辐射剂量。

Objective To compare different doses of acute appendicitis enhanced diagnostic CT of the abdomen. Methods Selected 72 patients with acute appendicitis from May 2013 to May 2015 in our hospial, which werer divided into the control group and the observation group, each group had 36 cases. The obsrevation group given low dose abdomen enhanced diagnostic CT, the control group given routine dose abdomen enhanced diagnostic CT, Compared two groups of patients with the diagnosis that dose. Results There were scanning dose（9.1±3.1） m Gy, effective m As（79±24） m As, scan dose control group（23.5±6.3） m Gy, effective m As（195±45） m As, dose and scanning the observation group effective m As than the control group, a significant difference between two groups（P〈0.05）, no significant difference in two groups（P〉0.05）. Conclusion Acute appendicitis low dose abdominal CT scan can reduce the radiation dose by the patient.
