Free-Breathing Magnetization Transfer Imaging of the Lung at 0.55 T Using bSTAR.
Article in Magnetic resonance in medicine, 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
purposeTo develop a clinically applicable method for magnetization transfer (MT) imaging of the lung at 0.55 T.
methodsMT imaging of the chest was explored in healthy volunteers at 0.55 T using a self-gated 3D half-radial dual-echo balanced steady-state free precession sequence (bSTAR), a 2D multi-slice gradient echo method (GRE) acquired in end-expiratory breath-hold, and a self-gated 3D half-radial single-echo ultra-short TE (UTE) approach. MT contrast relied on RF pulse prolongation for bSTAR and on pulsed off-resonance irradiation for UTE and GRE. Data reconstruction from the self-gated scans was performed offline and for the end-expiratory tidal phase using a compressed sensing algorithm. MT ratio (MTR) maps were derived from an MT-weighted and a non-MT-weighted scan and took 8:32 min for bSTAR, 17:16 min for UTE, and 0:48 min for GRE. In addition, patients with pulmonary diseases underwent bSTAR MTR imaging.
resultsMT imaging was successfully performed in all volunteers with highly similar average MTR values for the lung of 28.8 pu (UTE), 29.4 pu (GRE), and 30.7 pu (bSTAR). In terms of resolution, however, bSTAR clearly outperformed both UTE and GRE variants. Finally, MTR imaging with bSTAR demonstrated high reproducibility in volunteers and showed substantially different MTR values for patients with various pulmonary diseases.
conclusionAt 0.55 T, MT-sensitized bSTAR offers in vivo high-resolution free-breathing MTR imaging of the entire lung in clinically acceptable scan times and shows high reproducibility. Initial results suggest that MTR imaging at 0.55 T may potentially serve as a noninvasive biomarker for investigating and differentiating pulmonary diseases.
