Predicting the True Extent of Glioblastoma Based on Probabilistic Tractography [PDF]

Frontiers in Neuroscience, 2022
Glioblastoma is the most frequent type of primary brain tumors. Despite the advanced therapy, most of the patients die within 2 years after the diagnosis.

Connectivity-Based Segmentation of the Thalamic Motor Region for Deep Brain Stimulation in Essential Tremor: A Comparison of Deterministic and Probabilistic Tractography

NeuroImage: Clinical
Objective: Deep brain stimulation (DBS) studies have shown that stimulation of the motor segment of the thalamus based on probabilistic tractography is predictive of improvement in essential tremor (ET). However, probabilistic methods are computationally

Probabilistic MRI tractography of the optic radiation using constrained spherical deconvolution: a feasibility study. [PDF]

PLoS ONE, 2015
Imaging the optic radiation (OR) is of considerable interest in studying diseases affecting the visual pathway and for pre-surgical planning of temporal lobe resections.

A comparison of diffusion tensor imaging tractography and constrained spherical deconvolution with automatic segmentation in traumatic brain injury

NeuroImage: Clinical, 2023
Detection of microstructural white matter injury in traumatic brain injury (TBI) requires specialised imaging methods, of which diffusion tensor imaging (DTI) has been extensively studied.

Evaluation of tractogram filtering methods using human-like connectome phantoms

NeuroImage, 2023
Tractography algorithms are prone to reconstructing spurious connections. The set of streamlines generated with tractography can be post-processed to retain the streamlines that are most biologically plausible.

Increased structural connectivity of thalamic stimulation sites to motor cortex relates to tremor suppression

NeuroImage: Clinical, 2021
Deep brain stimulation (DBS) of the ventral intermediate nucleus (VIM-DBS) is a highly successful treatment for medication-refractory essential tremor (ET). Clinical outcomes are dependent on accurate targeting.

Motor Evoked Potentials Improve Targeting in Deep Brain Stimulation Surgery

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives One of the main challenges posed by the surgical deep brain stimulation (DBS) procedure is the successful targeting of the structures of interest and avoidance of side effects, especially in asleep surgery. Here, intraoperative motor evoked potentials (MEPs) might serve as tool to identify the pyramidal tract.

Deep Brain Stimulation Reduces Conflict‐Related Theta and Error‐Related Negativity in Patients With Obsessive–Compulsive Disorder

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Obsessive–compulsive disorder (OCD) is a psychiatric disorder with alterations of cortico‐striato‐thalamo‐cortical loops and impaired performance monitoring. Electrophysiological markers such as conflict‐related medial frontal theta (MFT) and error‐related negativity (ERN) may be altered by clinically effective deep brain ...

Implementation of clinical tractography for pre-surgical planning of space occupying lesions: An investigation of common acquisition and post-processing methods compared to dissection studies.

PLoS ONE, 2020
BACKGROUND AND PURPOSE:There is limited standardization of acquisition and processing methods in diffusion tractography for pre-surgical planning, leading to a range of approaches.

Connectome spatial smoothing (CSS): Concepts, methods, and evaluation

NeuroImage, 2022
Structural connectomes are increasingly mapped at high spatial resolutions comprising many hundreds—if not thousands—of network nodes. However, high-resolution connectomes are particularly susceptible to image registration misalignment, tractography ...
