Effects of image reconstruction on fiber orientation mapping from multichannel diffusion MRI: reducing the noise floor using SENSE. by Sotiropoulos, SN, Moeller, S, Jbabdi, S, Xu, J, Andersson, J, Auerbach, E, Yacoub, E, Feinberg, D, Setsompop, K, Wald, L, Behrens, T, Ugurbil, K, Lenglet, C

“…PURPOSE: To examine the effects of the reconstruction algorithm of magnitude images from multichannel diffusion MRI on fiber orientation estimation. THEORY AND METHODS: It is well established that the method used to combine signals from different coil elements in multichannel MRI can have an impact on the properties of the reconstructed magnitude image. …”
