Three-dimensional microangiography of the mouse brain using super-resolution ultrasound and optoacoustic imaging with a spherical array transducer.

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
High-resolution visualization of the mouse brain microvasculature is essential for advancing neurovascular research and understanding neurological disorders. Recent advances in pulse-echo ultrasound (US) and optoacoustic (OA) imaging enable angiographic imaging beyond the acoustic diffraction limit through localization of microbubbles in ultrasound localization microscopy (ULM) and light-absorbing microparticles in localization optoacoustic tomography (LOT). Despite their distinct contrast mechanisms, a direct comparison has been lacking. Here, we evaluate three-dimensional motion-contrast US and OA imaging, including their super-resolved variants ULM and LOT, using the same ultrasound array, localization and tracking algorithms, and frame rates. Studies in mice of different ages reveal complementary strengths: OA/LOT offers higher-SNR for cortical imaging, especially in older animals with thicker skulls, while the lower attenuation of ultrasound enables US/ULM to achieve substantially greater penetration depth and whole-brain coverage. This comparison provides practical guidance for choosing optimal localization-based strategies for cerebrovascular studies.
