Abstract

Proton nuclear (¹H) is the observed nucleus on which most magnetic resonance imaging (MRI) applications depend. Most traditional ¹H MRI can provide structural and functional information about organisms, while various non-proton nuclei (X-nuclei) MRI can provide more metabolic information. However, due to the relatively poor signal-to-noise ratio (SNR) of X-nuclei MRI, their applications are quite rare compared to ¹H. Benefit from the rapid developments of MRI hardware and software technologies, X-nuclei MRI has recently attracted increasing interests in biomedical research. This review firstly introduces some current methods to improve the SNR of X-nuclei MRI. Secondly, this review describes biomedical applications of X-nuclei MRI, especially focusing on the current use of X-nuclei (¹³C, ¹⁷O, ¹⁹F, ²³Na and ³¹P) MRI to study related diseases in different organs, including the brain, liver, kidney, heart and bone. Finally, perspectives studies on X-nuclei imaging and its potential applications are described in biomedical research.

x核磁共振成像在生物医学研究中的综述与进展

质子核(1H)是大多数磁共振成像(MRI)应用所依赖的观测核。大多数传统的1H MRI可以提供生物体的结构和功能信息，而各种非质子核(x -核)MRI可以提供更多的代谢信息。然而，由于x核MRI的信噪比相对较差，与1H相比，它们的应用非常少。得益于MRI硬件和软件技术的快速发展，x -核MRI最近在生物医学研究中引起了越来越多的兴趣。本文首先介绍了目前提高x核MRI信噪比的几种方法。其次，综述了x -核MRI在生物医学上的应用，重点介绍了目前x -核(13C、17O、19F、23Na和31P) MRI在不同器官相关疾病研究中的应用，包括脑、肝、肾、心、骨。最后介绍了x核成像技术的研究前景及其在生物医学研究中的应用前景。
