MRI Detects pH Changes

Caption

University of Iowa researchers have developed an MRI-based method to detect and monitor pH changes in living brains. The image shows MRI brain scans of human subject breathing air (left) or air containing 7.5 percent carbon dioxide (middle). The difference between the two scans (shown right) shows increased brain acidity in red caused by carbon dioxide inhalation as measured by the new MRI-based strategy.
