Multi‐Parametric Phase‐Cycled Balanced Steady‐State Free Precession Brain Tissue Characterization in Relapsing‐Remitting Multiple Sclerosis

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Time‐efficient phase‐cycled balanced steady‐state free precession (pc‐bSSFP) imaging is a novel microstructure‐ and myelin‐sensitive approach for multi‐parametric brain tissue characterization not yet evaluated in demyelinating diseases such as multiple sclerosis (MS).

Comparison of Probabilistic and Deterministic Tractography Methods for Preoperative Ventral Intermediate Nucleus Deep Brain Stimulation Planning in Essential Tremor Patients

Clinical Neuroimaging
Introduction The ventral intermediate nucleus (VIM) is a key target for deep brain stimulation (DBS) in treating essential tremor (ET). However, conventional indirect targeting often overlooks individual anatomic variability.

Ventralis intermedius nucleus anatomical variability assessment by MRI structural connectivity

NeuroImage, 2021
The ventralis intermedius nucleus (Vim) is centrally placed in the dentato-thalamo-cortical pathway (DTCp) and is a key surgical target in the treatment of severe medically refractory tremor. It is not visible on conventional MRI sequences; consequently,

Functional Imaging for Identification of Functionally Critical Brain Regions to Spare in Glioma Radiation Therapy Planning: A Systematic Review

Journal of Medical Radiation Sciences, EarlyView.
This review highlights the role of functional imaging in sparing cognitive brain regions during glioma radiotherapy. It shows promising dose reduction without compromising target coverage, but evidence remains limited, requiring standardisation and prospective validation.

Probabilistic Tractography Using Q-Ball Modeling and Particle Filtering [PDF]

, 2011
By assuming that orientation information of brain white matter fibers can be inferred from Diffusion Weighted Magnetic Resonance Imaging (DWMRI) measurements, tractography algorithms provide an estimation of the brain connectivity in-vivo. The two key ingredients of tractography are the diffusion model (tensor, high-order tensor, Q-ball, etc.) and the ...

Consensus between pipelines in structural brain networks. [PDF]

, 2014
Structural brain networks may be reconstructed from diffusion MRI tractography data and have great potential to further our understanding of the topological organisation of brain structure in health and disease.

Merged Group Tractography Evaluation with Selective Automated Group Integrated Tractography (SAGIT)

Frontiers in Neuroanatomy, 2016
Introduction: Tractography analysis in group-based studies across large populations is difficult to manage and assess. We propose Selective Automated Group Integrated Tractography (SAGIT), an automated group tractography software platform that ...

7 T MRI Connectivity‐Guided Reprogramming Improves Deep Brain Stimulation Motor Outcome in Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an established treatment for Parkinson's disease (PD). Using 7‐Tesla (7 T) MRI connectivity analysis to visualize the patient‐specific STN motor subdivision, we hypothesize that reprogramming patients who are stimulated outside of this subdivision can improve their ...
