Biochemical state in tissue can be detected through ultrasound signal.
Article in npj biomedical innovations, 2025. 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
Three-dimensional (3D) cell cultures, such as spheroids, are indispensable models for investigating cellular behaviors and responses under conditions that closely resemble in vivo environments. Conventional imaging techniques, including optical microscopy, are often limited by penetration depth, complicating the analysis of structural and biochemical changes within dense 3D systems. This study demonstrates the application of ultrasound imaging for the non-invasive evaluation of internal dynamics in cancer spheroids. Scattering-based acoustic parameters revealed spatial variations in amplitude and brightness density, correlating with cellular proliferation, apoptosis, and necrosis. Amplitude in central regions progressively decreased after Day 3, approaching near-zero by Day 15, reflecting necrotic core formation. Artificial inhibition of myosin contractility significantly influenced these patterns, providing insights into biomechanical contributions to spheroid organization. The findings establish ultrasound imaging as a label-free, high-penetration technique capable of addressing critical challenges in 3D culture analysis, offering new opportunities for studying cellular dynamics in spheroids and organoid models.
