Advancing whole-brain BOLD functional MRI in humans at 10.5 T with motion-robust 3D echo-planar imaging, parallel transmission, and high-density radiofrequency receive coils.
Article in Magnetic resonance in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeTo demonstrate the feasibility and performance of whole-brain blood oxygen level-dependent functional MRI (fMRI) in humans at 10.5 T by combining motion-robust three-dimensional gradient-echo echo-planar imaging, parallel transmission, and high-density radiofrequency (RF) receive coils.
methodsResting-state fMRI time series were collected in healthy adults at 1.58 mm and approximately 2-s spatiotemporal resolution using a custom-built 16-channel transmit/80-channel receive RF array. Individualized parallel-transmission, spatial-spectral RF pulses were designed to achieve uniform water-selective excitation across the entire brain without the need for additional fat saturation. Images were reconstructed with navigator-guided joint motion and field correction. Reconstructed images were preprocessed using fMRIPrep and postprocessed using XCP-D pipelines. Relevant resting-state fMRI metrics were evaluated including temporal SNR (tSNR), amplitude of low-frequency fluctuation, and regional homogeneity. The results were compared with those obtained using uncorrected reconstruction (i.e., using same raw data but without motion or field correction).
resultsOur motion-corrected reconstruction largely improved image quality for fMRI time series, reducing motion confounds when compared with uncorrected reconstruction. The reduction in motion confounds translated into an improvement in tSNR, with tSNR averaged across all volunteers being increased by about 11%. Our motion-corrected reconstruction also improved both amplitude of low-frequency fluctuation and regional homogeneity in most cortical surfaces and subcortical regions.
conclusionIt is feasible to perform quality three-dimensional whole-brain blood oxygen level-dependent fMRI in humans at 10.5 T using a new comprehensive motion-robust imaging method. This work paves the way for promising future applications at 10.5 T aimed at studying brain function and networks with high spatiotemporal resolution.
