Deterministic fiber tracking
WebJan 29, 2024 · We performed deterministic fiber tracking using DSI Studio software (DSI Studio 2), which utilizes a generalized streamline fiber tracking method (Yeh et al., 2013). Parameters selected for fiber tracking included a step size of 0.2 mm, a minimum fiber length of 20 mm, and a turning angle threshold of 45°. For progression locations … WebApr 9, 2024 · [17][18][19][20] However, many studies focusing on fiber tracking used deterministic tractography, which applies only one main diffusion vector for each voxel. …

Deterministic maximum fiber tracking … WebJan 2, 2014 · Deterministic fiber tracking can be viewed as solving an ordinary differential equation [11], in which the fiber trajectory can be parameterized as r ( s ), r :R→R 3 , where s is the length of
WebOct 10, 2024 · Aiming to facilitate both deterministic and probabilistic tractography, we require our model to provide a probabilistic estimation of local fiber orientations prior to … WebAug 20, 2013 · In this study we used intraoperative stimulation from brain tumor patients as a gold standard to estimate the sensitivity and accuracy of diffusion tensor MRI (DTI) and q-ball models of diffusion with deterministic and probabilistic fiber tracking algorithms for delineation of motor pathways.
WebJul 29, 2024 · We rendered the DTI-based fiber bundle image onto the structural image acquired in FIESTA. The propagation of tractography was constrained by maintaining a FA threshold of 0.18. We manually placed the seeding on the volume-of-interest (VOI) for deterministic fiber tracking. The VOI was set based on the 3D color-coded FA map … WebMethods: Deterministic fiber tracking (tractography) of whole brain white matter was performed on 13 epilepsy patients pre- and post-callosotomy. The analysis of structural connectivity was based on graph theory and network-based analysis with a focus on the inter- and intrahemispheric networks. Clinical demographic data including seizure ...
