Advanced optical phantom mimicking microvascular and directed blood flow in mouse brain.
Article in Biomedical engineering letters, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The accurate replication of cerebral hemodynamics is essential for advancing neuroimaging techniques and preclinical research. This study presents a novel multi-component dynamic optical phantom designed to model the complex blood flow dynamics of the mouse brain. The phantom incorporates a static base mimicking skull optical properties, a porous medium infused with a blood-mimicking solution to simulate microvascular perfusion, and a directed flow channel representing large vessels such as the sagittal sinus. The phantom structure was characterized using laser speckle contrast imaging (LSCI) to assess its ability to replicate in vivo-like blood flow patterns. The results demonstrate strong quantitative agreement between the phantom and transcranial LSCI measurements of mouse brain hemodynamics. Our key findings highlight the influence of tissue-mimicking perfusion structures and optical attenuation properties on the blood flow index, validating the phantom as a reproducible and physiologically relevant model. This optically tunable and dynamically controllable platform provides a robust tool for calibrating neuroimaging technologies, validating new optical diagnostic techniques, and investigating cerebral blood flow regulation in preclinical studies.
