An inductively coupled implanted coil was designed for high-resolution magnetic resonance (MR) studies of rat spinal cord (SC) in vivo at 7 T. The practical issues involved in implementation of the coil at high fields are discussed, and the adjustment of various parameters for optimizing coil performance are described. The utility of the coil was demonstrated with anatomical, magnetization transfer, diffusion tensor imaging, and proton MR spectroscopy (MRS).
设计了一种电感耦合植入式线圈，用于在7 T场强下对大鼠脊髓进行高分辨率活体磁共振（MR）研究。讨论了在高场强下实施该线圈所涉及的实际问题，并描述了为优化线圈性能而对各种参数进行的调整。通过解剖学、磁化传递、扩散张量成像和质子磁共振波谱（MRS）证明了该线圈的实用性。
