MR neurography (MRN) is a useful technique to evaluate damaged peripheral nerves showing increased signal intensity and enlarged nerve diameter. Although various MRN sequences have been developed, the inter-rater reliability of MRN have rarely been evaluated. Therefore, the purpose of this study was to evaluate inter-rater reliability of sciatic nerve evaluation with MRN sequences: T2WI, 3D-STIR, T2-FFE, 3D-iNerveVIEW, Diffusion-neurography, DTI, and pcDSDE. Measured diameters varied among the sequences. 3D-iNerveVIEW showed a high inter-rater reliability for signal measurements. In MRN, it is important to understand the characteristics of each sequence.
