A Near-Field Coupling Array Enables Parallel Imaging and SNR Gain in MRI.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Wireless radiofrequency (RF) coils based on metasurfaces hold great promise for improving clinical magnetic resonance imaging (MRI) workflows by eliminating the need for cable connections to the patient bed and simplifying coil structures. A fundamental requirement for their clinical adoption is the ability to support parallel imaging, which reduces examination time and improves efficiency. Moreover, the implementation of parallel imaging often comes at the expense of image signal-to-noise ratio (SNR). Although several wireless RF coils incorporating metamaterials are reported, most do not support parallel imaging and many deliver suboptimal SNR performance. In this work, a novel wireless RF coil architecture is proposed, termed the near-field coupling array (NFCA), which demonstrates both excellent SNR performance and robust parallel imaging capabilities. A general theoretical framework is presented that establishes a foundation for applying metasurface arrays in magnetic resonance RF coil design. The SNR expression for this architecture is derived from two perspectives, and its fundamental principles are validated through case studies. Experimental results show that the NFCA achieves a 66% SNR improvement over a conventional commercial RF coil architecture (i.e., a wired coil) while its average acceleration factor exceeds 94% of that of the commercial coil.
