Measuring in vivo blood perfusion within the brown adipose tissue depot of the human supraclavicular fossa is highly relevant in metabolic and obesity research. DW-MRS can probe perfusion properties by measuring the IVIM signal of the water peak. However, DW-MRS of the supraclavicular fossa remains a challenging task due the high sensitivity of the region to motion and the associated poor spectral quality. The present work proposes a DW-MRS methodology with a flow compensated acquisition combining cardiac and respiratory tracking to improve spectral quality. IVIM results for the water peak are shown for the first time in the supraclavicular fossa.
