Improved detection of spinal cord lesions using an axial T2-weighted TSE sequence with full spinal cord coverage compared to sagittal T2-weighted TSE and STIR sequences in multiple sclerosis: a prospective study.
Article in Neuroradiology, 2025. 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
objectiveThis study aimed to compare the detection rates and inter-rater agreements of the sagittal T2w-TSE and sagittal short tau inversion recovery (STIR) sequence versus the axial T2w-TSE sequence with full spinal cord coverage in identifying spinal cord lesions in patients with suspected demyelinating diseases and diagnosed multiple sclerosis (MS).
methods104 patients were prospectively enrolled in this study and underwent MRI, including a sagittal T2w-TSE and STIR sequence, as well as an axial T2w-TSE sequence with full spinal cord coverage. Two experienced neuroradiologists, blinded to clinical parameters, independently evaluated the scans in separate sessions. After blinded readings, raters re-evaluated all sequences to assess if lesions could be retrospectively identified in other sequences.
resultsSpinal cord lesions were found in 81 patients. The highest inter-rater reliability was observed for the sagittal T2w-TSE sequence (κ = 0.73, 95%-CI 0.66-0.79), followed by the axial T2w-TSE (κ = 0.71, 95%-CI 0.63-0.79) and the sagittal STIR sequence (κ = 0.65, 95%-CI 0.58-0.73). The axial T2w-TSE sequence demonstrated superior lesion detection rates, identifying significantly more lesions (n = 361) compared to the STIR (n = 293) and T2w-TSE sagittal (n = 224) sequence (p < 0.001).
conclusionAxial T2w-TSE sequences with full spinal cord coverage provide superior lesion detection compared to sagittal sequences and should be included in standard MRI protocols for MS patients. They may accelerate meeting MRI criteria for MS, improve monitoring of disease progression, and enhance prediction of future disability.
