A radiologist is a hospital doctor trained in radiation and in pictures of the inside of the body. A tidy learner-dictionary line may say they treat people with radiation, and that is not wholly false: some radiologists do procedures, and radiation belongs to their world.

A radiologist放射科醫師 is是 trained in radiation and in pictures of the inside of the body受過放射線與身體內部影像訓練的 a hospital doctor醫院醫師。A tidy learner-dictionary line簡化的學習詞典 may say可能會說 they treat people with radiation他們用放射線治療病人，and that is not wholly false這並非完全錯：some radiologists do procedures有些放射科醫師確實會做處置，and radiation belongs to their world放射線也算是他們的領域。

But the messy truth in most hospitals is this: the radiologist is the doctor who studies the X-rays and other scan pictures, then writes a report so other doctors know what they show. You often never meet them. You meet the radiographer who takes the picture; later your own doctor reads the radiologist’s words.

But但 the messy truth in most hospitals大多數醫院裡真實的情況 is this是：the radiologist放射科醫師 is是 the doctor who studies the X-rays and other scan pictures負責研究X光和其他掃描影像的醫師，then writes a report然後寫報告 so other doctors know what they show讓其他醫師知道影像顯示了什麼。You often never meet them你常常根本不會見到他們。You meet the radiographer who takes the picture你見到的是負責拍片的放射師；later之後 your own doctor你自己的醫師 reads the radiologist's words看的是放射科醫師寫的文字。

The doctor whose main job is aiming a radiation beam at a cancer is more often called a radiotherapist, or a radiation oncologist. Students mix those titles constantly, and that is understandable — they all start with radio- and they all live in the same corridor.
