摘要
目的:通过多层螺旋CT胸部低剂量扫描检测肺肿块及结节的灵敏度的能力及放射剂量的分析,来探讨低剂量CT扫描在肺癌及结节随访中的价值。材料与方法:对200例已经明确为肺部肿瘤的患者以低剂量及常用规剂量的定期检查的CT图像对比。结果:低剂量与(30、40、50ma)与常规剂量(190ma),低剂量对患者的辐射影响比常规剂量低很多,而对病灶的部位、大小数目分布无明显差异,对医生诊断无影响。结论:多排螺旋CT低剂量扫描与常规扫描CT结果一致,在高危人群肺癌筛查及结节随访中有效的做到早发现早治疗,大大节约家庭及社会成本,因此具有很高的操作性及临床应用价值。
Purpose： To analyze low-dose multislice spiral CT scan of the chest and the ability to detect lung tumors and radiation dose nodule sensitivity to explore low-dose CT scanning in lung cancer and follow-up of nodules. Materials and Methods ： 200 eases of lung eaneer have a clear CT images of patients with low doses of regular inspection and common regula- tory dose contrast. Results： Low dose （30, 40, 50 ma） with conventional dose （190ma）, the effect of low dose radiation on patients is much lower than conventional doses, and the site of the lesion, no significant difference in the number size distribu- tion, has no effect on medical diagnosis. Conclusion： Consistent multi-slice spiral CT scan with conventional low-dose CT scan results, screening for lung cancer in high-risk populations and effective follow-up of nodules do early detection and early treat- ment, significant savings in the cost of the family and society, and therefore has a high maneuverability and clinical application.
