Multidimensional RF pulse design using auto-differentiable spin-domain optimization and its application to reduced field-of-view imaging.
Article in Magnetic resonance in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeDevelop a general radiofrequency (RF) pulse design algorithm for the design of three-dimensional (3D) spatially selective refocusing pulses and explore their potential applications in reduced field-of-view imaging.
methodsSpin-domain representation was used to describe the effect of RF pulses and to formulate the optimization problem. The implementation was based on an auto-differentiable simulator. Spatially selective excitation and refocusing pulses for a small regions of interest were designed with consideration of hardware limits and B
resultsPulses of short duration (4.15 ms) were designed for 3D tailored excitation and refocusing accounting for B
conclusionThe proposed algorithm jointly optimizes the RF and gradient waveforms given an initial pulse and a desired spin-domain target pattern. Our approach is broadly applicable to the design of excitation and refocusing pulses and complements existing methods based on describing individual spin isochromatic behavior. Combining 3D excitation and 3D refocusing pulses produced better spatial selectivity than using a combination of one-dimensional and 3D pulses.
