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.
虽然阿西莫夫虚构的“正电子”大脑并不存在，但是正电子理论确确实实被应用于正电子衍射成像（PET）扫描技术上用来探索人类大脑。
Positron-emission tomography (PET) is superior to CT and MRI in deciding the nature of lymph nodes and identifying the local changes after radiotherapy.
正电子发射断层扫描（PET）在判断颈部淋巴结的性质及鉴别放疗后局部异常改变优于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.
研究综合使用了正电子发射断层成象仪(PET)以及断层扫描成象仪(CT)，以识别褐色脂肪。

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.
