Human in vivo 31P spectroscopy of skin: potentially a powerful tool for noninvasive study of metabolism in a cutaneous tissue.
The first application of human in vivo phosphorus (31P) magnetic resonance spectroscopy to analysis of skin metabolism is presented. Our results confirm that phosphocreatine is a major energy phosphometabolite in human skin. Human in vivo 31P spectroscopy utilizing a skin coil designed in our laboratory can have clinical applications in cutaneous surgery and clinical dermatology, and will facilitate understanding of the pathophysiology of skin disease. In vitro experiments with fresh human skin indicate that complete utilization of phosphocreatine is followed by utilization of adenosine triphosphate (ATP) molecules during ischemia. These experiments also suggest that the majority of phosphocreatine in human skin is localized in epidermal and papillary dermis.
