1 · What the graph read from it

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.

2 · The registry

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

backgroundMetallic components in magnetic resonance imaging (MRI)-guided robotic catheters, such as leadwires and microcoils, can interact with the scanner's radiofrequency (RF) fields, causing heating via the antenna effect and Joule heating, leading to localized temperature rises and an increased risk of thermal injury. Ensuring thermal safety will enable safe and reliable operation of magnetically actuated robotic catheters within MRI environments. PURPOSE: This study aims to develop a novel MRI-compatible robotic catheter design that mitigates RF-induced and resistive heating, ensuring patient safety and proper functionality during MRI-guided interventions, particularly for cardiac ablation procedures. The catheter is directly actuated by magnetic torques generated on current-carrying microcoils at the tip by the MRI scanner's static magnetic field, allowing precise navigation.

methodsThe catheter design incorporates systematically tuned microcoil parameters and distributed capacitors along the leadwires to suppress resonance and minimize RF energy absorption. A dithering technique applying actuation currents at a 50

resultsThe prototype exhibited a maximum temperature increase of 0.6

conclusionsThe catheter design effectively mitigates both RF-induced and resistive heating under the tested conditions. These results demonstrate the suitability of the design for MRI-guided interventional procedures under the tested conditions, while remaining within FDA temperature limits.
