PROGRAM

Educational Objectives:

Upon completion of this workshop, participants should be able to:
  • Identify the biochemical assumptions, metabolic modeling and MR spectroscopic methods utilized to measure neurotransmitter metabolism and the metabolic coupling between neuronal and glial cells:
  • Discuss the relationship between neuronal activity, cerebral blood flow, oxidative metabolism, BOLD fMRI and electrical activity in the brain and how they can be measured using MR spectroscopy and imaging;
  • Discuss how MR spectroscopy can be used to quantify the flux through major metabolic pathways in the liver, and their relationship to diabetes;
  • Describe the methodology and assumptions underlying MR measurements of intra-myocellular and intra-hepatic lipids and their role in the development of obesity and diabetes;
  • Describe how MR spectroscopy and imaging can be used to identify ischemic heart disease.
