Conclusions and relevance: This study found that at current utilization and radiation dose levels, CT examinations in 2023 were projected to result in approximately 103 000 future cancers over the course of the lifetime of exposed patients. If current practices persist, CT-associated cancer could eventually account for 5% of all new cancer diagnoses annually.

CT-associated cancer could eventually account for 5% of all new cancer diagnoses annually 你怕什么LOL
5% 已经非常高了
几年做一次， 大概可以接受吧。 肺癌发病率那么高， 应该几年就做一次 x 光之类的。
MRI 没事， 是强磁场， 没有任何放射性。
比普通xray 大一点，但是比CT小多了。
你可以回复医生：把人放在油锅里炸一分钟接受的热量，其实也只相当于在外面晒太阳几天而已。
怎么知道自己做的是low dose? 是不是没有contrast的都是low dose?
low dosage CT 呢？ 国内体检经常有这个项目
其实主要是针对非必要就不要做ct，如果是必要那也没办法。国内主要很多检查大量上ct，很多人以为核磁共振有辐射，ct没有。。。
