Relaxometry-based water compartmentalization is the most
accurate and precise method for separating brain tissue
and cerebral spinal fluid (CSF) water signals in proton
MRI and MRS; however, its long acquisition times make
the technique one of rare use in quantitative
spectroscopy. Here we examine the use of one-minute
RRAMSC (

for calculating brain metabolite concentrations in molal
units.
