Wrist magnetic resonance imaging (MRI) is essential for evaluating soft‐tissue injury, bone marrow edema, and small‐joint abnormalities, yet high‐quality imaging still relies largely on dedicated wrist coils and often requires the uncomfortable prone “superman” position. Here, we present a clinically adaptive gradien...
The accuracy of quantitative magnetic resonance imaging (qMRI) largely depends on the image signal‐to‐noise ratio (SNR). In recent years, studies on metamaterials in MRI have shown that they can significantly improve image quality through weak coupling with the body coil or receive coil. However, it is still unclear...

Improving the signal-to-noise ratio (SNR) is crucial for enhancing image quality and diagnostic reliability in magnetic resonance imaging (MRI). However, traditional methods that rely on increasing the number of coil channels are approaching their physical and engineering optimization limits. In recent years, wireless,...
