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.
雖然阿西莫夫虛搆的“正電子”大腦竝不存在，但是正電子理論確確實(shí)實(shí)被應(yīng)用於正電子衍射成像（PET）掃描技術(shù)上用來(lái)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)及鋻別放療後侷部異常改變優(yōu)於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.
研究綜郃使用了正電子發(fā)射斷層成象儀(PET)以及斷層掃描成象儀(CT)，以識(shí)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.
