Brain Metabolism Observed at 7 Tesla
Description
The goal is to establish a protocol to 13C-label (from 13C-glucose) several physiological molecules: glucose, lactate, pyruvate and derived compounds. All of these molecules can undergo oxidation in the citric acid cycle. The intent is to study the 13C labeling pattern of these molecules in control and G1D subjects to determine if downstream products (such as 13C bicarbonate or 13C glutamate) due to oxidation in the mitochondria can be detected in brain or in blood by NMR analysis. While inside the instrument, the subjects may also undergo a 7T MR exam to correlate spectroscopy with brain structure.
