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 investigate the display rate of appendix lesion in low-dose supine position and left oblique prone supine abdominal CT examination in order to improve the diagnostic ability of appendix lesions. Methods: A total of 160 clinical appendicitis patients were randomly divided into two groups. MSCT abdomen examination was performed in low-dose supine position and left-oblique prone position, and the imaging diagnosis results were compared with postoperative pathology. Results: The sensitivity, specificity and accuracy of low dose left oblique prone position scanning in observing appendix lesions were significantly higher than those in low dose supine position scan (P <0.05). Conclusion: Low dose left oblique prone abdominal CT examination can improve the detection rate of appendix lesion, which is helpful for the diagnosis of early appendix lesions.
