射频（RF）线圈之于磁共振成像（MRI）扫描仪就像眼睛之于人体。由于它们的重要性，不断的创新推动了射频线圈技术的快速发展。在过去的四十年中，射频线圈技术发展的广度和深度远远超过了这篇综述文章所允许的空间。然而，这些过去的发展为最近的一些技术突破奠定了基础。在这里，我们将重点放在一些最新的射频线圈进展上，特别是柔性、无线和集成线圈阵列。为了提供详细的回顾，我们讨论了这些令人兴奋的主题的理论基础，实验实现，有希望的结果以及未来的展望。这些最新的创新极大地改善了患者的舒适度和扫描的便利性，同时也提高了信噪比、图像分辨率、时间吞吐量以及诊断和治疗的准确性。与其他核磁共振子领域的进步一起，它们无疑将继续推动该领域向前发展，并引领我们走向更加令人兴奋的未来。证据水平：5技术功效：第1阶段
Radio-frequency (RF) coils are to magnetic resonance imaging (MRI) scanners what eyes are to the human body. Because of their critical importance, there have been constant innovations driving the rapid development of RF coil technologies. Over the past four decades, the breadth and depth of the RF coil technology evolution have far exceeded the space allowed for this review article. However, these past developments have laid the very foundation on which some of the recent technical breakthroughs are built upon. Here, we narrow our focus on some of the most recent RF coil advances, specifically, on flexible, wireless, and integrated coil arrays. To provide a detailed review, we discuss the theoretical underpinnings, experimental implementations, promising results, as well as future outlooks covering these exciting topics. These recent innovations have greatly improved patient comfort and ease of scan, while also increasing the signal-to-noise ratio, image resolution, temporal throughput, and diagnostic and treatment accuracy. Together with advances in other MRI subfields, they will undoubtedly continue to drive the field forward and lead us to an ever more exciting future. Level of Evidence: 5 Technical Efficacy: Stage 1
