Signal-to-noise assessment for diffusion tensor imaging with single data set and validation using a difference image method with data from a multicenter study
PURPOSE: To describe a quantitative method for determination of SNR that extracts the local noise level using a single diffusion data set. METHODS: Brain data sets came from a multicenter study (eight sites; three MR vendors). Data acquisition protocol required b = 0, 700 s/mm(2), fov = 256 × 256 mm...
