[Abstract] Radiofrequency coils, as critical components of MRI systems, serve the essential functions of transmitting and receiving signals. Over the past four decades, coil design and development have undergone significant evolution—from volume coils to the recently introduced wireless coils—achieving groundbreaking advancements in wireless technology, flexibility, and lightweight design. Wireless coils have garnered increasing attention for their ability to eliminate the need for cable connections while significantly improving image quality. The core value of wireless coils lies in their ability to substantially enhance image quality in targeted regions without requiring cable connections or independent power supplies, while simultaneously avoiding hardware modifications to existing MRI systems and associated high costs. Compared to traditional approaches of improving image quality by adding multi-channel standard receiving coils, wireless coils demonstrate notable advantages including portability, cost-effectiveness, compatibility with mainstream brand equipment, and enhanced patient comfort. This article will elucidate the technical principles and innovative applications of wireless coils, summarize current developments of wireless coils, analyzes the current limitations of research, and proposes future research directions, providing a reference for the clinical popularization of wireless coils.
