There is a paucity of studies trying to investigate the sensitivity of DTI metrics like Fractional Anisotropy (FA), Apparent Diffusion Coefficient (ADC), Axial Diusivity and Radial Diffusivity in areas corresponding to the lesion sites detected in clinical MRI using FLAIR images. Aim of this study was to compare the utility of DTI with FLAIR by evaluating the contrast to noise ratio (CNR) in their detecting capacity of DAI lesions and to evaluate whether DTI is more accurate than FLAIR or vice versa.
