The use of specialized coils to improve signal-to-noise ratios in magnetic resonance (MR) imaging is an important innovation. The role of surface coils has not yet been well defined, but it seems likely that they will be routinely used for clinical imaging of the orbit, neck, and spine. Surface coils have important limitations that make other designs, such as "closely coupled" volume coils, attractive for some applications, especially for limb imaging. With improvement in our ability to visualize anatomy with MR imaging, specialized radio frequency coils may provide new imaging capabilities for clinical problems that were not previously considered to be indications for diagnostic imaging.
在磁共振（MR）成像中使用专用线圈来提高信噪比是一项重要的创新。表面线圈的作用尚未得到很好的界定，但它们很可能会被常规用于眼眶、颈部和脊柱的临床成像。表面线圈有重要的局限性，这使得其他设计，如“紧密耦合”容积线圈，在某些应用中具有吸引力，特别是对于肢体成像。随着我们利用MR成像可视化解剖结构能力的提高，专用射频线圈可能会为以前未被视为诊断成像适应症的临床问题提供新的成像能力。
