ABSTRACT
Purpose To investigate the diameter change of dorsal root ganglion (DRG) in lumbar disc herniation using three-dimensional MR neurography. Materials and Methods Sixty-ifve patients with lumbar disc herniation and 30 healthy volunteers were selected. Bilateral DRG diameter was measured using MR three-dimensional constructive interference steady state (3D-CISS) sequence at the level of L3-S1 in the control group and at the level of herniation disc in patient group including central and lateral subgroups. The relationship between the sagittal index and DRG diameter at the level of herniation disc was analyzed. Results In the control group, the DRG diameters increased from the level of L3 to S1. The DRG diameters of the central subgroup were bigger than those of the control group (t=-2.485--2.253, P0.05). The sagittal index was not correlated with DRG diameter. Conclusion 3D-CISS sequence clearly demonstrates morphological changes of lumbosacral nerve root and measures its diameter.
