摘要
目的:探讨低剂量仰卧位与左斜俯卧位腹部CT检查对阑尾病变的显示率,以提高阑尾病变的诊断能力。方法:收集160例临床拟诊阑尾炎的患者随机分两组,行低剂量仰卧位与左斜俯卧位MSCT腹部检查,将影像诊断结果与术后病理进行对比分析。结果:采用低剂量左斜俯卧位扫描观察阑尾病变的敏感度、特异性及准确率明显高于低剂量仰卧位扫描(P<0.05)。结论:低剂量左斜俯卧位腹部CT检查可提高阑尾病变检出率,有助于阑尾早期病变的诊断。
Objective to assess visualization rate of appendix in patients with lower abdominal pain using low dose CT scan examination technology in supine position or left oblique prone position, to improve the diagnosis ability of appendix lesions. Methods 160 patients of clinical examination of appendicitis were randomly divided into two groups and take low dose MSCT scan in supine position or left oblique prone position. The CT findings were analyzed and compared with surgical pathology. Result： Sensitivity, specificity and accuracy of appendix lesion were higher with Left oblique prone scan than supine scan （P 〈 0.05）. Conclusion： Low dose CT scan examination technology in left oblique prone position can obviously improve the detection rate of appendix lesion, was helpful in early diagnose of appendix lesions.
