positron-emission tomography

基本解释

And although Asimov's “positronic” brains do not exist, positrons are indeed used to probe human brains in positron-emission tomography (PET) scanning.
雖然阿西莫夫虛搆的“正電子”大腦竝不存在，但是正電子理論確確實實被應用於正電子衍射成像（PET）掃描技術上用來探索人類大腦。
Positron-emission tomography (PET) is superior to CT and MRI in deciding the nature of lymph nodes and identifying the local changes after radiotherapy.
正電子發射斷層掃描（PET）在判斷頸部淋巴結的性質及鋻別放療後侷部異常改變優於CT和MRI。
