A graphic example of registration of lesion masks. FLAIR = axial fluid-attenuated inversion recovery MRI images; T1 = 2D axial non-enhanced T1-weighted spin-Echo or 3D non-enhanced T1-weighted gradient-Echo MRI images; SPM = Statistical Parametric Mapping; FSL = FMRIB Software Library; FLIRT = FMRIB’s Linear Image Registration Tool; r_T1 = registered 2D axial non-enhanced T1-weighted spin-Echo or 3D non-enhanced T1-weighted
