It is now common practice to use radiofrequency (RF) coils to increase the signal-to-noise ratio (SNR) in 1H magnetic resonance imaging and spectroscopy experiments. Use of array coils for non-1H experiments, however, has been historically more limited despite the fact that these nuclei suffer inherently lower sensitivity and could benefit greatly from an increased SNR. Recent advancements in receiver technology and increased support from scanner manufacturers have now opened greater options for the use of array coils for non-1H magnetic resonance experiments. This paper reviews the research in adopting array coil technology with an emphasis on studies of the most commonly studied non-1H nuclei including 31P, 13C, 23Na, and 19F. These nuclei offer complementary information to 1H imaging and spectroscopy and have proven themselves important in the study of numerous disease processes. While recent work with non-1H array coils has shown promising results, the technology is not yet widely utilized and should see substantial developments in the coming years.
在氢质子（¹H）磁共振成像和光谱实验中，使用射频（RF）线圈来提高信噪比（SNR）现已成为常规做法。然而，尽管这些原子核本身灵敏度较低，增加信噪比能使其受益匪浅，但在非¹H实验中使用阵列线圈的历史却较为有限。近期，接收器技术的进步以及扫描仪制造商的更多支持，为非¹H磁共振实验使用阵列线圈提供了更多选择。本文回顾了采用阵列线圈技术的研究，重点关注对最常研究的非¹H原子核的研究，包括³¹P、¹³C、²³Na和¹⁹F。这些原子核为¹H成像和光谱提供了补充信息，并且在众多疾病过程的研究中已证明自身的重要性。虽然近期关于非¹H阵列线圈的研究已显示出有前景的结果，但该技术尚未得到广泛应用，预计在未来几年会有显著发展。
