Diffusion tractography of the fornix in schizophrenia [PDF]

Schizophrenia Research, 2009
White matter fiber tracts, especially those interconnecting the frontal and temporal lobes, are likely implicated in pathophysiology of schizophrenia. Very few studies, however, have focused on the fornix, a compact bundle of white matter fibers, projecting from the hippocampus to the septum, anterior nucleus of the thalamus and the mamillary bodies ...

Performance of unscented Kalman filter tractography in edema: Analysis of the two-tensor model

NeuroImage: Clinical, 2017
Diffusion MRI tractography is increasingly used in pre-operative neurosurgical planning to visualize critical fiber tracts. However, a major challenge for conventional tractography, especially in patients with brain tumors, is tracing fiber tracts that ...

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.

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).

Transformer-Based T1-Tractography

2025 IEEE 22nd International Symposium on Biomedical Imaging (ISBI)
Diffusion MRI (dMRI) streamline tractography has been the gold standard for non-invasive estimation of white matter (WM) pathways in the human brain. Recent advancements in deep learning have enabled the generation of streamlines from T1-weighted (T1w) MRI, a more common imaging method.

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.

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 ...

Staged Bilateral Magnetic Resonance‐Guided Focused Ultrasound for Treating Essential Tremor: Systematic Review and Meta‐Analysis

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Unilateral magnetic resonance guided focused ultrasound (MRgFUS) thalamotomy reduces tremor in essential tremor, yet disability often persists on the untreated side. The added benefit and safety of a staged contralateral lesion remain uncertain.
