Cover Story: Although impaired brain energy metabolism due to mitochondrial dysfunction isconsidered to be a major contributing factor for various neurodegenerative diseases, non-invasive and quantitative assessment of human brain energy metabolism is challenging. In this work, we demonstrate that by utilizing advanced ultrahigh field in vivo 31P MRS based metabolic imaging technology, it is possible to quantify key metabolic–energetic parameters in human brains, including the concentration of major phosphorous metabolites related to ATP energy and phospholipid metabolism, intracellular pH and NAD redox state, the activity of ATPase and Creatine Kinase, and the corresponding cerebral ATP production rates. These advanced technologies can detect subtle metabolic and bioenergetic changes at an early stage of neurodegeneration and provide exciting opportunities for monitoring disease progression and/or treatment response.
