Superferromagnetic Disk Particles for Magnetic Particle Imaging.
Article in Small methods, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Magnetic particle imaging (MPI) offers rapid, highly sensitive tracer-based imaging without ionizing radiation, but its clinical translation remains challenged by the limited performance of existing superparamagnetic (SP) tracers. In this work, precisely engineered disk-shaped nanoparticles fabricated from superferromagnetic (SF) discontinuous metal-insulator multilayers (DMIMs) consisting of SP nanoscale metal islands embedded in a nonmagnetic oxidic matrix are introduced. By leveraging inter-island exchange interactions, robust SF behavior is achieved in extended DMIMs, exhibiting exceptionally high susceptibilities and a sharp magnetization switching at fields below 1 mT. When evaluated in MPI experiments, magnetic disk particles (MDP) with a diameter of 1800 nm patterned from the SF DMIMs demonstrate up to a 1.6-fold improvement in spatial resolution and a 2.4-fold increase in sensitivity compared to Perimag tracers, the current gold standard in MPI. System matrix measurements and hybrid MPI reconstructions further highlight the superior imaging characteristics of MDP tracers in complex, clinically relevant geometries. These findings establish SF DMIM disks as a promising next-generation tracer platform for MPI, with the potential to simplify scanner designs and to pave the way for a clinical translation of MPI.
