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

backgroundConventional phased-array torso coils used for abdominal MRI are relatively heavy and inflexible, potentially affecting patient comfort and technologist workflow.

objectiveTo compare image quality, patient experience, and technologist experience using a recently United States Food and Drug Administration-cleared flexible, lightweight, blanket-like torso coil versus a conventional torso coil for pediatric abdominal MRI. MATERIALS AND

methodsIn this prospective institutional review board-approved study, 20 pediatric patients (7 years-old to 18 years-old) undergoing routine clinical outpatient abdominal MRI were imaged on the same 1.5-T system using both a conventional torso coil and a flexible blanket-like torso coil (Smart Fit TorsoCardiac; Philips Healthcare). After standard clinical imaging, selected sequences were repeated following coil exchange. Five pediatric radiologists independently evaluated paired image sets for subjective signal-to-noise ratio (SNR) and coil-related artifacts. Objective image quality was assessed using organ- and tissue-based SNR estimates and contrast-to-noise ratio (CNR) measurements. Patients and MRI technologists completed questionnaires regarding comfort, usability, and examination experience.

resultsAll 20 patients (median age, 15 years; 55% female) underwent imaging with both coils. Radiologists rated the novel coil as similar to the conventional coil for subjective SNR across all three sequences under study; coil-related artifacts were uncommon (2% of assessments for all sequences evaluated). Objective analysis showed no significant image-based SNR differences for most sequences, although the flexible coil demonstrated higher liver SNR on axial diffusion-weighted imaging (adjusted P=0.01). CNR did not differ between coils. Patients reported greater comfort and less anxiety with the flexible coil; 55% preferred it for future MRI examinations versus 20% for the conventional coil. Technologists also favored the flexible coil, with 70% expressing an overall preference.

conclusionThe flexible blanket-like torso coil provided image quality similar to a conventional coil and was generally preferred by patients and MRI technologists.
