Dartmouth physicians and engineers are collaborating to test new imaging techniques to find breast abnormalities, including cancer. Results from their latest study, which involved magnetic resonance-guided near-infrared imaging, appear in the May 22 issue of the Proceedings of the National Academy of Sciences (PNAS).
"This paper is the culmination of five years of work to build a completely new type of imaging system, which integrates magnetic resonance imaging (MRI) and near-infrared imaging (NIR)," says Brian Pogue, associate professor of engineering and one of the authors of the study.
He explains that because infrared light is sensitive to blood, researchers can locate and quantify regions of oxygenated and deoxygenated hemoglobin by sending infrared light through breast tissue with a fiber optic array. This might help detect early tumor growth and characterize the stage of a tumor by learning about its vascular and cellular makeup.

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
