Diffusion Tensor Imaging-Based Research on Human White Matter Anatomy
The Scientific World Journal, 2012 The aim of this study is to investigate the white matter by the diffusion tensor imaging and the Chinese visible human dataset and to provide the 3D anatomical data of the corticospinal tract for the neurosurgical planning by studying the probabilistic ...

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).

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.

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 ...

NeuroImage, 2020 Diffusion MRI tractography processing pipeline requires a large number of steps (typically 20+ steps). If parameters of these steps, number of threads, and random seed generators are not carefully controlled, the resulting tractography can easily be non ...

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.

Med Research, EarlyView.This study characterizes multimodal structural–functional alterations across the Alzheimer's disease (AD) continuum. We integrated diffusion tensor imaging, resting‐state functional MRI, and cognitive assessments from the ADNI cohort to examine white matter integrity, default mode network (DMN) organization, and cognitive performance.

White matter integrity assessed by diffusion tensor tractography in a patient with a large tumour mass but minimal clinical and neuropsychological deficits [PDF]
, 2012 Diffusion tensor imaging (DTI) tractography and image registration were used to investigate a patient with a massive left-sided brain tumor, whose size was largely disproportionate to his subtle neurological deficits.
