Fig. 2From: Diffusion tensor imaging for assessment of microstructural changes associate with treatment outcome at one-year after radiofrequency Rhizotomy in trigeminal neuralgiaBar charts of the DTI metrics in the lesion and normal sides and of the ablated and untreated sides after radiofrequency rhizotomy (RFA). A significant increase in the FA and decreases in the ADC, AD and RD were noted in a lesion undergoing RFA. (FA: fraction anisotropy; ADC: apparent diffusion coefficient; AD: axial diffusivity; RD: radial diffusivity)Back to article page
