Brainstem Diffusion Tensor Tractography and Clinical Applications in Pain

Frontiers in Pain Research, 2022
The brainstem is one of the most vulnerable brain structures in many neurological conditions, such as pain, sleep problems, autonomic dysfunctions, and neurodegenerative disorders.

Scoping literature review: Comparing MRI tractography methods for optic radiation analysis

The Anatomical Record, EarlyView.
Abstract Accurate tractography mapping of the optic radiations is essential to avoiding post‐operative visual field deficits in patients undergoing temporal lobe surgery. This literature review highlights the current landscape of MRI tractography methods that are used to delineate the optic radiations (ORs), with a particular focus on the anterior ...

Development of interactive MRI‐based 3D visualization tools for neuroanatomy education in Latin America

Anatomical Sciences Education, EarlyView.
Abstract The study of neuroanatomy is fundamental in many scientific fields. Despite this, it is a challenging subject for students. As technology evolves, it is being increasingly incorporated into educational methods, including the teaching of neuroanatomy. Three‐dimensional (3D) visualizations are well suited for displaying neuroanatomy.

“Hands‐On” white matter anatomy: Using Air Anatomy gestures and tractography on simple brain sections to enhance teaching of white matter directions

Anatomical Sciences Education, EarlyView.
Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.

Tractography of Meyer's Loop asymmetries

Epilepsy Research, 2014
The purpose of the current study was to use diffusion tensor imaging (DTI) to conduct tractography of the optic radiations (OR) and its component bundles and to assess both the degree of hemispheric asymmetry and the inter-subject variability of Meyer's Loop (ML).

Feasibility study to unveil the potential: considerations of constrained spherical deconvolution tractography with unsedated neonatal diffusion brain MRI data

Frontiers in Radiology
PurposeThe study aimed to (1) assess the feasibility constrained spherical deconvolution (CSD) tractography to reconstruct crossing fiber bundles with unsedated neonatal diffusion MRI (dMRI), and (2) demonstrate the impact of spatial and angular ...

Show Me the Brain!!: A modern approach to neuroanatomy education

Anatomical Sciences Education, EarlyView.
Abstract Show Me the Brain!! (SMtB) is a digital system for interactive graphics that is designed to support instruction in neuroanatomy and neuroscience. It will soon be made open‐source and freely available. SMtB bridges medical and traditional neuroanatomy instruction with the computational systems and representational conventions common in ...

Automated Diffusion Tensor Tractography [PDF]

Academic Radiology, 2012
Diffusion tensor tractography offers a unique perspective of white matter anatomy, but proper delineation of white matter tracts of interest generally requires the active involvement of an expert neuroanatomist. The investigators describe the implementation of an automated tractographic method requiring no user input and compare its results to those ...

The Evolving Role of Clinical Anatomy: From Definition to Contribution

Clinical Anatomy, EarlyView.
ABSTRACT The term “clinical anatomy” is widely used in education and research, yet its conceptual boundaries continue to be interpreted in various ways. Prior consensus‐based efforts have emphasized integration, collaboration, and clinical relevance as central features of the field and have provided an important foundation for interdisciplinary ...

What's a White Matter ‘Fiber’?

Clinical Anatomy, EarlyView.
ABSTRACT White matter anatomy is investigated using methods that operate at markedly different spatial scales and rely on distinct biological and physical principles. Nevertheless, the term “fiber” is routinely applied to the outputs of tract‐tracing studies, diffusion MRI tractography, and postmortem fiber dissection, often as though these entities ...
