One-click co-registered T2 mapping and dual black- and bright-blood late gadolinium enhancement MRI for comprehensive assessment of myocardial injury after acute STEMI.
Article in European heart journal. Imaging methods and practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Aims: In acute ST-segment elevation myocardial infarction, ischaemia and reperfusion lead to a cascade of myocardial injury that can be characterized by cardiac magnetic resonance (CMR) imaging, including coagulation necrosis, oedema, papillary muscle damage, microvascular obstruction, and intramyocardial haemorrhage. Conventional CMR protocols require multiple sequences to be performed and complicated analysis. This study evaluates SPOT-MAPPING, a sequence that acquires co-registered T2 maps and dual bright- and black-blood late gadolinium enhancement (LGE) images in a single scan. Methods and results: SPOT-MAPPING employs a single-shot, ECG-triggered 2D sequence alternating between bright- and black-blood LGE imaging with varying T2 weightings. We prospectively enrolled 20 STEMI patients undergoing CMR at 1.5 T within 4-7 days post-emergent coronary intervention. SPOT-MAPPING's segmentation times and reproducibility of myocardial injury markers (oedema, scar size, transmurality, papillary muscle damage) were assessed against conventional T2 mapping and phase-sensitive inversion recovery (PSIR). SPOT-MAPPING halved left ventricular wall segmentation time (∼3 min) while maintaining high reproducibility for oedema, scar size, and transmurality (ICC > 0.8). It improved papillary muscle damage detection over PSIR (8 vs. 3 patients) and showed comparable T2 values with conventional T2 mapping (remote: 45.0 ± 3.6 ms vs. 45.9 ± 3.7 ms, Conclusion: SPOT-MAPPING offers a time-efficient and reproducible CMR method for myocardial injury assessment post-STEMI.
