Summary

Dr. Mangia is Assistant Professor in the Department of Radiology at the University of Minnesota. She got her master degree in Physics (1999), the Ph.D. in Biophysics (2003) and the title of "Specialist in Medical Physics" (2005) at the University of Rome "La Sapienza" (Italy). Since 2004 she has been working at the Center for Magnetic Resonance Research (CMRR).

Research

Research Summary/Interests

  • Functional studies of human brain metabolism under increased or decreased neuronal activity
  • Neurovascular coupling and neuro-glia interactions
  • Oxidative and non-oxidative brain metabolism; glucose and lactate metabolism
  • Novel MR contrasts based on rotating frame relaxation measurements, magnetization transfer and chemical exchange
  • Applications of novel MRI/MRS protocols for studies of neurological diseases as Parkinson’s disease, schizophrenia, multiple sclerosis
  • Measurements of blood flow with arterial spin labeling methods, and their application to diseases as diabetes
  • Proton NMR Spectroscopy at high fields
  • Resting state fMRI, especially in relation to brain metabolism
