Togao O, et al. - Researchers assessed the usefulness of glycosaminoglycan chemical exchange saturation transfer (gagCEST) imaging in the quantitative assessment of intervertebral disc degeneration in a comparison with Pfirrmann grade and T1-ρ measurements. For this investigation, 96 lumbar intervertebral discs in 24 volunteers were studied with both gagCEST imaging and T1-ρ measurements. The findings from the present study suggested that gagCEST imaging could be a safe and quantitative technique for evaluating intervertebral disc degeneration.
