[Noninvasive functional lung imaging with hyperpolarized xenon : Breakthrough for diagnostics?]
Review in Radiologie (Heidelberg, Germany), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMagnetic resonance imaging (MRI) is a noninvasive technique that provides excellent contrast for soft tissue organs. However, due to the low density of protons and many air-tissue junctions, its application in the lung is limited. Thus, X‑ray-based methods are often used here (with the well-known disadvantages of ionizing radiation).
objectivesIn this review, we discuss pulmonary MRI with hyperpolarized xenon-129 (Xe-MRI). Xe-MRI provides unique valuable insights into lung microstructure and function, including gas exchange with red blood cells-parameters not accessible by any standard clinical methods.
methodsBy magnetic labelling, i.e. hyperpolarization, the signal from xenon-129 is amplified by up to 100,000 times. In this process, electrons from rubidium are first polarized to 100% using laser light and then transferred to xenon by collisions. Then the hyperpolarized gas is brought to the patient in a bag and inhaled shortly before the MRI scan.
resultsUsing special programming (sequences) of the MRI, the ventilation, microstructure, or gas exchange of the lungs, can be displayed in 3D. This allows, for example, quantitative visualization of ventilation defects, alveolar size, tissue gas uptake and gas transfer to the blood.
conclusionsXe-MRI provides unique information about the state of the lung-noninvasively, in vivo and in less than a minute.
