CT 辐射比X光小多了吧，该检查还得检查呀

还是应该看数字。比如100%+1% 跟没用一样。

说反了。一个CT Scan 相当于100-800个X ray 的辐射量。CT scans require more exposure to radiation than common x-rays because they use a series of x-ray images.

别担心，每年自然辐射剂量：The Canadian average is 1.77 mSv. CT scans 计量见表内。To date, there is no evidence of genetically heritable risk in humans from exposure to x-rays.

问题是都不得不做了，有得选吗？兩害取其轻，遵医嘱，该咋办就咋办吧。

增加癌症风险1 in 2000，但因人在自然界的癌症风险是400 chances in 2000，因此总共，CT增加风险从 400 chances in 2000 to 401 chances in 2000.
