Magnetic Resonance Imaging of Human Supraclavicular Brown Adipose Tissue - MIBAT Study (MIBAT)

April 5, 2018 updated by: University Hospital, Basel, Switzerland

Brown adipose tissue (BAT) is unique in its capability to convert chemical energy directly into heat. Active BAT increases energy expenditure and can thereby counteract obesity and insulin resistance. Currently, the imaging method of choice to assess BAT morphology and function is 18F-FDG-PET/CT which is expensive and exposes patients or healthy volunteers to ionizing radiation, thus impeding larger prospective studies.

Magnetic resonance imaging (MRI) could constitute a suitable alternative and preliminary small-scale studies are promising.

The overall aim of this research proposal is to develop reliable magnetic resonance imaging techniques to facilitate the study of brown adipose tissue in human adults, specifically in the context of endocrine disease.

Specifically, investigators want to

  1. Develop a reliable MR imaging protocol for human BAT and compare BAT volume to cold induced nonshivering thermogenesis as a measure of BAT activity.
  2. Assess the intra-individual variance of BAT volume measured by MRI.
  3. Evaluate direct measurement of BAT temperature by functional MRI.
