We present the results from sodium magnetic resonance imaging (MRI) experiments using high-temperature superconducting (HTS) receiver coils. Sodium imaging has been shown to have great potential for the assessment of cell integrity but suffers from a substantially lower signal-to-noise ratio (SNR) than that of a hydrogen imaging. The use of an HTS receiver coil was found to significantly increase the SNR relative to an equivalent copper receiver coil at room temperature. The SNR gains afforded by HTS coils can also be used to decrease the imaging time.
我们展示了使用高温超导（HTS）接收线圈进行钠磁共振成像（MRI）实验的结果。钠成像已被证明在评估细胞完整性方面具有巨大潜力，但与氢成像相比，其信噪比（SNR）要低得多。研究发现，与室温下等效的铜接收线圈相比，使用HTS接收线圈可显著提高SNR。HTS线圈带来的SNR增益还可用于缩短成像时间。
