L5 dorsal root ganglion (DRG) volume and normalized signal intensity (SI) versus neuropathy disability score (NDS) and neuropathy symptom score (NSS). (A) Correlation of NDS and L5 DRG volume in patients with diabetic polyneuropathy [DPN; (r = –0.43; 95%CI = –0.66 to –0.14; p = 0.02)]. (B) DRG volumetry of a patient with a total L5 DRG volume of 277 mm3. (C) DRG volumetry of a patient with a total L5 DRG volume of 94 mm3. (D) Correlation of L5 DRG SI and NSS in painful DPN (r = 0.80; 95%CI = 0.46 to 0.93; p = 0.005). (E) L5 DRG SI in a patient with severe painful DPN (SI = 0.61 ± 0.094). (F) L5 DRG SI in a patient with mild painful DPN (SI = 0.45 ± 0.054).
