23Na MRI was applied in five healthy volunteers to determine the feasibility of intervertebral discs sodium signal quantification using the cerebrospinal fluid signal from the spinal column as an internal reference. There were no significant differences between the five measured volunteers, or between the different discs (L1/2 – L5/S1), that were analysed. Therefore, internal referencing using CSF has the potential for sodium content quantification in intervertebral discs, which may be used as an indicator of disc degeneration.
