摘　　要：目的探讨BI-RADS分级和乳腺增生与全数字化乳腺摄影辐射剂量(入射体表剂量和平均腺体剂量)的相关性。方法回顾性收集252例行全数字化乳腺X线摄影的受检者资料,将受检者年龄按照<30岁、30-39岁、40-49岁、50-59岁、60-69岁、≥70岁进行分组,分析BI-RADS分级和乳腺增生与全数字化乳腺摄影辐射剂量的相关性。结果受检者不同年龄组间的辐射剂量(AGD和ESD)均有统计学差异(P<0.05),且<30岁年龄组的ESD均值最高,50-59岁年龄组的AGD均值最高;BI-RADS分级与辐射剂量(AGD和ESE)无统计学意义(P>0.05),乳腺增生与辐射剂量(AGD和ESE)有统计学意义(P<0.05)。结论受检者年龄差异会影响辐射剂量(AGD和ESD),BI-RADS分级不会影响辐射剂量(AGD和ESD),但乳腺增生会影响辐射剂量(AGD和ESD),因此,操作技师应对年龄组别差异和乳腺增生的受检者给予更多的辐射剂量关怀。Objective To explore the correlation between BI-RADS grading,breast hyperplasia and radiation dose(entrance surface dose(ESD)and average gland dose(AGD))of full-field digital mammography(FFDM).Methods The data of 252 patients undergoing full digital mammography were retrospectively collected,and the patients were divided into groups according to the age of<30 years old,30-39 years old,40-49 years old,50-59 years old,60-69 years old,and≥70 years old.The correlation between BI-RADS grade and breast hyperplasia and radiation dose of FFDM was analyzed.Results There were statistical differences in radiation dose(AGD and ESD)among different age groups(P<0.05),and the mean value of ESD was the highest in<30 years old age group,and the mean value of AGD was the highest in 50-59 years old age group.There was no statistical significance between BI-RADS grade and radiation dose(AGD and ESD)(P>0.05),but there was statistical significance between breast hyperplasia and radiation dose(AGD and ESD)(P<0.05).Conclusion Age differences among subjects can affect radiation dose(AGD and ESD),while BI-RADS grading does not affect radiation dose(AGD and ESD).However,breast hyperplasia can affect radiation dose(AGD and ESD).Therefore,operating technicians should pay more attention to radiation dose for subjects in age groups and breast hyperplasia.The age difference of the examinee can affect the radiation dose(AGD and ESD),the BI-RADS grading will not affect the radiation dose(AGD and ESD),but the breast hyperplasia will affect the radiation dose(AGD and ESD).Therefore,the operator should pay more attention to radiation dose care to examinees with age group differences and breast hyperplasia.
