岛津移动DR低剂量肺部普查的可行性实验研究

目的：探讨岛津移动DR低剂量肺部普查的最佳扫描参数。方法：将300例胸部检查者随机分2组：常规参数检查组（120kV，5mAs）；低剂量组（110kV，1．2mAs）。结果：所有图像均符合诊断要求，图像质量均为优，低剂量较常规剂量的X线量少．2组图像无明显差异。结论：低剂量摄片能提供与常规剂量相近的诊断信息，适当的调整参数既可以使受检者所受剂量降低，适用于大规模体检人群的普查，又可以延长机器使用寿命。

Feasibility of Application of Mobile Shimadzu DR to Low-dose Lung Screening

Objective To explore the ideal parameters for the application of mobile shimadzu DR to low-dose lung screening. Methods 300 subjects were divided into two groups randomly, of which, one went through conventional screening with 120 kV voltage and 5mA current intensity, and the other through low-dose screening with 110 kV voltage and 1.2 mA intensity. Results All the images from two groups could satisfy the diagnosis requirements and had no aparent difference. Conclusion Low-dose screening, with similar result to the conventional one, can decrease radiation dose and prolong the service life of the machine, and thus can be used for examination of large-scale population.
