Multi-subregional susceptibility patterns in gliomas using sub-voxel quantitative susceptibility mapping [PDF]

European Radiology Experimental
Objective To evaluate glioma susceptibility patterns and their clinical/pathological correlations using a sub-voxel quantitative susceptibility mapping (QSM) technique that quantifies the paramagnetic (χpara) and diamagnetic (χdia) components (APART-QSM).

Insights From Quantitative Susceptibility Mapping: An Umbrella Review of Multiple Sclerosis [PDF]

Health Science Reports
Background and Aims Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system characterized by demyelination and neurodegeneration. Conventional MRI techniques lack specificity for detecting subtle pathological changes, such

Quantitative susceptibility mapping of brain iron in adult ADHD [PDF]

Frontiers in Psychiatry
BackgroundAttention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition that frequently persists into adulthood and is linked to alterations in fronto-striatal circuitry and dopaminergic signaling. Brain iron is essential for dopamine

QSMART: Quantitative susceptibility mapping artifact reduction technique

NeuroImage, 2021
Purpose: Quantitative susceptibility mapping (QSM) is a novel MR technique that allows mapping of tissue susceptibility values from MR phase images. QSM is an ill-conditioned inverse problem, and although several methods have been proposed in the field ...

Brain pathological changes during neurodegenerative diseases and their identification methods: How does QSM perform in detecting this process?

Insights into Imaging, 2022
The presence of iron is essential for many biological processes in the body. But sometimes, for various reasons, the amount of iron deposition in different areas of the brain increases, which leads to problems related to the nervous system.

APART-QSM: An improved sub-voxel quantitative susceptibility mapping for susceptibility source separation using an iterative data fitting method

NeuroImage, 2023
The brain tissue phase contrast in MRI sequences reflects the spatial distributions of multiple substances, such as iron, myelin, calcium, and proteins. These substances with paramagnetic and diamagnetic susceptibilities often colocalize in one voxel in ...
