Fig. 4From: Diffusion tensor imaging for assessment of microstructural changes associate with treatment outcome at one-year after radiofrequency Rhizotomy in trigeminal neuralgiaA summary of changes of the volume and diffusion tensor metrics of the trigeminal nerve in a patient with trigeminal neuralgia is shown. Upper table: a comparison between the TN of the lesion side before and after RFA. Lower table: a comparison between the TN of the lesion and normal sides after RFA. (FA: fractional anisotropy; ADC: apparent diffusion coefficient; AD: axial diffusivity; RD: radial diffusivity; RFA: radiofrequency rhizotomy)Back to article page
