A new MRI method developed at the University of Arizona by Associate Professor Mark "Marty" Pagel, Ph.D., produces an image that maps the acid content in tissues. This map of a cross-section through the torso shows a tumor at the right side, which has an acidic pH of 6.6 that is shown in blue. A tube of water is used as a reference during the research study.
