MR Micro-Neurography and a Segmentation Protocol Applied to Diabetic Neuropathy

Figure 3

Tibial nerve with chronic degenerative changes (left (A, B)) compared with a volunteer (right (C, D)). The patient was in the group of the moderate/severe DPN and suffered from chronic pain and severe motor impairment. (A, C) Sequence: TSE T1. (B, D) Sequence: IDEAL-WATER. There is a visual increase of the interfascicular tissue (epineurium), while the fascicles appear reduced in number and area. Increase of fat and fibrous tissue within the epineurium is common in chronic stage of diabetic neuropathy.
