Reconstruction of white matter fibre tracts using diffusion kurtosis tensor imaging at 1.5T: Pre-surgical planning in patients with gliomas Joao Leote, Rita G. Nunes, Luis Cerqueira, Ricardo Loução, Hugo A. Ferreira European Journal of Radiology Open Volume 5, Pages 20-23 (January 2018) DOI: 10.1016/j.ejro.2018.01.002 Copyright © 2018 The Authors Terms and Conditions

Fig. 1 Transverse contrast-enhanced T1-weighted images (T1), echo planar images (EPI), fractional anisotropy (FA) maps and diffusion kurtosis invariant metrics (AK: axial kurtosis; MK: mean kurtosis; RK: radial kurtosis) maps of a healthy subject and patients with gliomas. Note the distortion of the fibres with cranial-caudal direction (i.e. coloured in blue) produced by the tumor in the pathological hemispheres. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)

Fig. 2 Mean tract sizes for whole-brain (A) and corticospinal (B) tractography of healthy subjects and patients groups (error bars translate standard deviation). Statistically significant differences in tracts and voxel numbers between groups were not found despite the smaller standard deviation in patients’ corticospinal tract (CST) size. Representative streamlined fibre bundles of CST are also presented (C). Note the pronounced mass effect imposed by the tumor presence in CST’s and their close proximity.
