positron-emission tomography

基本解釋

And although Asimov's “positronic” brains do not exist, positrons are indeed used to probe human brains in positron-emission tomography (PET) scanning.
雖然阿西莫夫虛構(gòu)的“正電子”大腦并不存在，但是正電子理論確確實(shí)實(shí)被應(yīng)用于正電子衍射成像（PET）掃描技術(shù)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(fā)射斷層掃描（PET）在判斷頸部淋巴結(jié)的性質(zhì)及鑒別放療后局部異常改變優(yōu)于CT和MRI。
The studies combined images taken with positron-emission tomography, or PET machines, with those from computed tomography, or CT machines, to identify the brown fat.
研究綜合使用了正電子發(fā)射斷層成象儀(PET)以及斷層掃描成象儀(CT)，以識別褐色脂肪。

The method combines an examination by positron emission tomography with a drug that lights up beta-amyloid.

Initially, Dr Zeki employed a scanning technique called positron-emission tomography to investigate these regions.
