Image quality evaluation of decubitus lumbar spine MRI using a flexible coil and PROPELLER sequence: comparison with conventional supine MRI.
Article in Skeletal radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo evaluate image quality of decubitus lumbar spine MRI using a flexible coil with or without Periodically Rotated Overlapping Parallel Lines with Enhanced Reconstruction (PROPELLER) sequence compared to that of the conventional supine lumbar spine MRI. MATERIALS AND
methodsThis study was conducted on patients who underwent decubitus lumbar spine MRI applying a flexible coil at a single center between February 1 and March 11, 2025, and had a Numeric Rating Scale (NRS) pain score ≥ 5, while examining supine MRI. Signal-to-noise ratio (SNR) in T2-weighted fast-spin-echo (FSE) sequence for supine, decubitus, and PROPELLER sequence at decubitus position were measured and compared using the Wilcoxon signed-rank test. Two radiologists independently evaluated the subjective image quality of each spine MRI.
resultsA total of 35 patients (mean age, 66 ± 13 years) were included in our study. On T2-weighted sagittal images, cerebrospinal fluid (CSF) SNR was highest in the supine
conclusionImage quality of decubitus lumbar spine MRI using a flexible coil was clinically feasible with acceptable image quality. PROPELLER sequence improved SNR
