Water peaks in MRS changed with the solute
concentrations of NaCl, Glu, and Alb. Differences in water peaks were observed
among the CSF phantom simulating normal, bacterial meningitis, and obstruction
of the subarachnoid space samples.
Figure 5
Compared to artificial CSF simulating normal CSF, artificial CSF simulating bacterial meningitis and artificial CSF simulating obstruction of the subarachnoid space showed higher peaks and lower signal values at the side slope of the peak.

The peak heights/FWHMs of each albumin concentration were as follows: 2 mmol/L: 4.73×1011/0.016 ppm, 0.2 mmol/L: 2.08×1011/0.080 ppm, 0.02 mmol/L: 8.71×1011/0.016 ppm, 0.01 mmol/L: 9.75×1011/0.020 ppm, and 0.005 mmol/L: 9.45×1011/0.020 ppm.
