In magnetic resonance imaging (MRI), contrast agents are used to enhance the imaging of tissue structures. While they enhance signals in blood vessels and in spaces between cells, they do not reach the interior of the cell. By contrast, glucose is taken up and then broken down in the body cells. Tumor cells are particularly hungry for glucose in order to feed their high energy needs. By observing glucose metabolism activity it may therefore be possible to identify solid tumors or very aggressively growing tumor areas. Radiologists and physicists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) in Heidelberg have now succeeded in employing this novel type of imaging.
