Core Insights - The French National Institute of Health and Medical Research has successfully developed a novel imaging technology that allows for high-precision mapping of blood circulation in key organs (heart, kidneys, and liver) using a four-dimensional imaging approach [1][2] - This new non-invasive ultrasound probe can distinguish small blood vessels with diameters less than 100 micrometers, enabling the visualization of microcirculation at the organ scale [1] - The technology is expected to enhance the understanding of the circulatory system's dynamics and assist in diagnosing blood circulation-related diseases, with plans for clinical trials to validate its application in humans [2] Group 1 - The research team has created a complete blood circulation map for the heart, kidneys, and liver in animal models, achieving unprecedented levels of imaging resolution and four-dimensional capabilities [1] - Microcirculation, a complex network of tiny blood vessels, is crucial for delivering oxygen and nutrients to tissues and organs, and its dysfunction can lead to severe clinical consequences [1] - The study has been published in the journal Nature Communications, indicating its significance in the scientific community [2]
