Initial assessment of PNS safety for interventionalists during image-guided procedures.
Article in Magma (New York, N.Y.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeThis study investigates peripheral nerve stimulation (PNS) safety thresholds for health professionals performing MRI procedures and the variation of arm rotations in close vicinity to the magnet bore.
methodsEmploying two posable human body models, this research utilized quasi-static electromagnetic calculations and neurodynamic simulations to assess PNS thresholds. Different arm rotations are compared for standing interventionalist's posture assuming the supine patient position, typical for medical interventions inside MRI devices.
resultsThis study reveals that arm rotations in standing postures result in variations in PNS thresholds. However, for all the arm poses considered, the threshold was at least 2.4 times higher compared to the patient position. Differences in PNS thresholds and electric field distributions were observed between male and female models.
conclusionsThe findings suggest that when the PNS thresholds for imaging subjects are not exceeded, it is likely that a subject leaning into the bore will also not experience PNS. However, variations in PNS thresholds due to arm movements highlight the importance of considering body posture in MRI safety protocols.
