In this work we present our results obtained at the 7T MRI scanner investigating the nerves in the forearm. We tested two DTI protocols and were able to visualize the median, ulnar and radial nerves with fiber tractography with resolution up to 0.75×0.75×2.0 mm³. We have demonstrated the potential of 7T to identify these nerves and quantify their diffusion characteristics in a reliable way. We expect that the use of high resolution DTI can be beneficial in the investigation of peripheral nervous tissue in the forearm and might aid in identifying changes due to pathology.
