正电子发射计算机断层扫描 meaning in Chinese

positron emission tomography

It supports information - sharing , enhancing the whole system ' s performance , reliability , stability and the ability of fault toleration by applying information synergetically , remedying the limitation which results from segmental and inaccurate information , various medical images provide different information of the organ concerned . for example , ct and mri provide distinctly anatomical information , and pet and spect provide organic function information though their space resolution are relatively low . though multiple medical images can obviously provide more complete and comprehensive information , the information may be contradicted in some cases
不同的医学图像捉供了相关脏器的不同信息：比如， ct ( computedtomography ，计算机x线断层扫描)和mri ( magneticresonanceimage ，磁共振成像)以较高的空间分辨率提供了脏器的解剖结构信息，而pet ( positiveelectrontomography ,正电子发射计算机断层扫描)和spect ( emissioncomputedtomography ，单光子发射断层扫描)尽管空间分辨率较差，但提供了脏器的新陈代谢功能信息。
