Fast, Robust T2-IVIM Quantitative MRI With Distortion and Motion-Corrected Multi-Echo EPI.

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
purposeTo enable robust, motion- and distortion-corrected T2-IVIM parameter estimation within clinically feasible scan times.
methodsA single-shot, multi-echo spin-echo EPI sequence was used to acquire abdominal diffusion-weighted MRI with time-efficient sampling of b-value and TE pairs. The multi-echo acquisition enabled distortion correction using reverse phase-encoding between echoes. Motion and distortion correction were applied before fitting a joint T2-IVIM model across the b-value and TE dimensions to obtain TE-independent IVIM parameters and compartment-specific T2 estimates. For comparison, a previously established single-echo T2-IVIM protocol with longer scan times and a single-echo protocol matched to the multi-echo parameters were acquired. Uncertainty was evaluated with wild bootstrap error analysis.
resultsThe multi-echo approach enabled motion- and distortion-corrected T2-IVIM mapping in under 5 min, compared with 11-13 min for the prior minimal single-echo protocol or nearly 19 min when acquired as separate shots. The liver was selected as the target organ due to its marked sensitivity to
conclusionThe combination of multi-echo sequence design and artifact correction enabled stable fitting of the extended T2-IVIM model with improved liver coverage and less than half the scan time of prior protocols. These advances support broader clinical applicability of T2-IVIM imaging by reducing acquisition burden while enhancing artifact correction and parameter robustness.
