A new technique developed by researchers at the University of California, Davis, offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal <a href="https://www.nature.com/articles/s41565-020-0678-5"><em>Nature Nanotechnology</em></a>.</p> May 25, 2020 - 4:35pm Andy Fell /curiosity/news/new-double-contrast-technique-picks-small-tumors-mri Look What’s Inside: Full-Body Movies From EXPLORER Scanner /news/look-whats-inside-full-body-movies-explorer-scanner <p>Positron emission tomography, or PET scanning, a technique for tracing metabolic processes in the body, has been widely applied in clinical diagnosis and research&nbsp;spanning physiology, biochemistry and pharmacology. Now researchers at the University of California, Davis, and Fudan University, Shanghai, have shown how to use an advanced reconstruction method with an ultrasensitive total-body PET scanner to capture real-time videos of blood flow and heart function. The work paves the way for looking at the function of multiple organs, such as the brain and heart, at the same time.</p> January 21, 2020 - 4:13pm Andy Fell /news/look-whats-inside-full-body-movies-explorer-scanner
