Neurite orientation dispersion and density imaging (NODDI) for the detection of focal cortical dysplasia (FCD). The FCD (circle) is defined poorly on volumetric T1- (A) and T2-weighted coronal oblique (B) images and on standard diffusion images including fractional anisotropy (C) and mean diffusivity (D) maps. However, it is clearly visible as reduced intracellular volume fraction on NODDI (E). Adapted from Winston et al. Epilepsy Res 2014;108:336-9 [41].
