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.

The role of spatial embedding in mouse brain networks constructed from diffusion tractography and tracer injections

NeuroImage, 2021
Diffusion MRI tractography is the only noninvasive method to measure the structural connectome in humans. However, recent validation studies have revealed limitations of modern tractography approaches, which lead to significant mistracking caused in part

Retinal neurovascular alterations are associated with optic radiation microstructure in adrenomyeloneuropathy: A susceptibility separation MRI study

VIEW, EarlyView.
In a cross‐sectional cohort of 104 participants, 7 T susceptibility separation MRI and diffusion imaging were combined with retinal imaging and visual evoked potentials to characterize visual pathway involvement in adrenomyeloneuropathy (AMN). Absolute diamagnetic susceptibility, a myelin‐associated measure, and fractional anisotropy (FA) showed ...

Diffusion MRI fiber tractography of the brain [PDF]

, 2017
: The ability of fiber tractography to delineate non\u2010invasively the white matter fiber pathways of the brain raises possibilities for clinical applications and offers enormous potential for neuroscience. In the last decade, fiber tracking has become

Reconstruction of the arcuate fasciculus for surgical planning in the setting of peritumoral edema using two-tensor unscented Kalman filter tractography

NeuroImage: Clinical, 2015
Background: Diffusion imaging tractography is increasingly used to trace critical fiber tracts in brain tumor patients to reduce the risk of post-operative neurological deficit.

Muscle morphology and intramuscular fat after treatment‐as‐usual including botulinum neurotoxin A injections in children with cerebral palsy

Developmental Medicine &Child Neurology, EarlyView.
Normalized muscle volume remained unchanged in all evaluated muscles after the 12‐month treatment‐as‐usual in children with cerebral palsy. Higher intramuscular fat fraction was observed in the medial gastrocnemius, suggesting concurrent intramuscular fat infiltration.

Exploring the Anatomical Basis of Effective Connectivity Models with DTI-Based Fiber Tractography

International Journal of Biomedical Imaging, 2008
Diffusion tensor imaging (DTI) is considered to be a promising tool for revealing the anatomical basis of functional networks. In this study, we investigate the potential of DTI to provide the anatomical basis of paths that are used in studies of ...

Diffusion spectrum imaging of patients with middle cerebral artery stenosis

NeuroImage: Clinical, 2022
Objective: We aimed to detect microstructural changes in the brains of patients with unilateral middle cerebral artery (MCA) stenosis and to assess the integrity of the fiber structure and the small-world networks using diffusion spectrum imaging (DSI ...

Retinopathy of Prematurity Is Associated With Reduced Thalamic Volume and Impaired Neurodevelopment. A Cohort Study

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Background Retinopathy of prematurity (ROP) is a neurovascular disorder that may affect not only the retina but also the brain structures involved in visual processing. The relationship between ROP severity and the volumetric development of these regions remains unclear.

The Superior Fronto-Occipital Fasciculus in the Human Brain Revealed by Diffusion Spectrum Imaging Tractography: An Anatomical Reality or a Methodological Artifact?

Frontiers in Neuroanatomy, 2017
The existence of the superior fronto-occipital fasciculus (SFOF) in the human brain remains controversial. The aim of the present study was to clarify the existence, course, and terminations of the SFOF.
