The aims of this study were to assess normative values for median nerve magnetization transfer ratio (MTR), apparent diffusion coefficient (ADC), fractional anisotropy (FA), cross sectional area (CSA), flatness ratio (FR), and signal-to-noise ratio (SNR), and to compare them with those of a patient with proven carpal tunnel syndrome (CTS). These normative values of the median nerve collected can be used as a reference for further studies in evaluating the role of these quantitative MR measurements in the evaluation, diagnosis, and follow-up of CTS.
