| 摘 要： | 一体式PET/MRI较其他多模态成像,如PETCT等具有明显的优点：同步采集、无射线危害、高软组织对比度,可实现各种功能成像等。一体式PET/MRI技术具有许多难点,如磁兼容性问题、PET和MRI的互相干扰问题,磁共振孔径有限等。一体式PET/MRI采用的技术包括基于光纤式、基于APD传感器式等,其中,APD传感器对设计全身临床型一体式PET/MRI更有前途。目前,一体式动物PET/MRI已应用较多,但临床型一体式PET/MRI尚处于初期发展阶段,不过初步的临床应用揭示PET/MRI对临床医学成像具有重要意义。

| Abstract: | Compared with other multi-modality imaging methods like PET/CT,the integrated PET/MRI has many obvious advantages,such as simultaneous acquisition,no radiation hazards,higher soft tissue contrast,various functional imaging.Integrated PET/MRI technology encountered many challenges,such as magnetic compatibility issues,mutual interference problems,and limited magnetic resonance aperture.Integrated PET/MRI uses technologies,such as fiber-based type,APD sensor type,etc.The APD sensor seems more valuable for des... |
