Mapping blood vessels and oxygenation throughout the whole mouse brain with dual-frequency fiber-array photoacoustic computed tomography.
Article in Light, science & applications, 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
A new all‑optical photoacoustic tomography system captures both low‑ and high‑frequency photoacoustic signals using an arc‑shaped fiber array. The high‑frequency channel resolves cortical vessels as fine as 70 μm near the surface; the low‑frequency channel reaches 1.2 cm to image the entire mouse brain. With ultrahigh sensitivity and blood oxygen saturation mapping, this dual‑frequency design alleviates the classic trade‑off between resolution and penetration-offering high‑resolution surface imaging and deep, wide‑field coverage within a single imaging platform.
