Preti MG, Makris N, Laganà MM, Papadimitriou G, Baglio F, Griffanti L, Nemni R, Cecconi P, Westin CF, Baselli G Conf Proc IEEE Eng Med Biol Soc 2012;2012:2283-6 PMID: 23366379 Abstract Diffusion Tensor Imaging (DTI) tractography and functional Magnetic Resonance Imaging (fMRI) investigate two complementary aspects of brain networks: white… read more →
Savadjiev P, Campbell JS, Pike GB, Siddiqi K Med Image Comput Comput Assist Interv 2008;11(Pt 1):135-43 PMID: 18979741 Abstract We introduce a fibre tract segmentation algorithm based on the geometric coherence of fibre orientations as indicated by a streamline flow model. The inference of local flow approximations motivates a pairwise… read more →
Savadjiev P, Rathi Y, Bouix S, Verma R, Westin CF Med Image Comput Comput Assist Interv 2012;15(Pt 3):34-41 PMID: 23286111 Abstract The geometry of white matter tracts is of increased interest for a variety of neuroscientific investigations, as it is a feature reflective of normal neurodevelopment and disease factors that… read more →
Lienhard S, Malcolm JG, Westin CF, Rathi Y EURASIP J Adv Signal Process 2011 Jan;2011 PMID: 24348546 Abstract We describe a technique that uses tractography to visualize neural pathways in human brains by extending an existing framework that uses overlapping Gaussian tensors to model the signal. At each point on… read more →
Melonakos J, Niethammer M, Mohan V, Kubicki M, Miller JV, Tannenbaum A Proc IEEE Int Conf Comput Vis 2007;:1-8 PMID: 23857521 Abstract In this paper, we describe a method for segmenting fiber bundles from diffusion-weighted magnetic resonance images using a locally-constrained region based approach. From a pre-computed optimal path, the… read more →
Savadjiev P, Rathi Y, Bouix S, Smith AR, Schultz RT, Verma R, Westin CF Med Image Comput Comput Assist Interv 2013;16(Pt 1):50-7 PMID: 24505648 Abstract Despite the fact that several theories link cortical development and function to the development of white matter and its geometrical structure, the relationship between gray… read more →
Beyond crossing fibers: bootstrap probabilistic tractography using complex subvoxel fiber geometries
Campbell JS, MomayyezSiahkal P, Savadjiev P, Leppert IR, Siddiqi K, Pike GB Front Neurol 2014;5:216 PMID: 25389414 Abstract Diffusion magnetic resonance imaging fiber tractography is a powerful tool for investigating human white matter connectivity in vivo. However, it is prone to false positive and false negative results, making interpretation of… read more →
Whitford TJ, Kubicki M, Pelavin PE, Lucia D, Schneiderman JS, Pantelis C, McCarley RW, Shenton ME Schizophr. Res. 2015 Jan;161(1):36-41 PMID: 25311780 Abstract BACKGROUND: Delusions of control are among the most distinctive and characteristic symptoms of schizophrenia. Several theories have been proposed that implicate aberrant communication between spatially disparate brain… read more →

Savadjiev P, Rathi Y, Bouix S, Smith AR, Schultz RT, Verma R, Westin CF Med Image Anal 2014 Dec;18(8):1349-60 PMID: 25066750 Abstract Current neuroimaging investigation of the white matter typically focuses on measurements derived from diffusion tensor imaging, such as fractional anisotropy (FA). In contrast, imaging studies of the gray… read more →
