Quantitative susceptibility mapping in atypical Parkinsonisms

NeuroImage: Clinical, 2019
Background and purpose: Differential diagnosis between Parkinson's disease (PD) and Atypical Parkinsonisms, mainly Progressive Supranuclear Palsy (PSP) and Multiple System Atrophy (MSA), remains challenging. The low sensitivity of macroscopic findings at

Quantitative Susceptibility Mapping in Parkinson's Disease.

PLoS ONE, 2016
BackgroundQuantitative susceptibility mapping (QSM) and R2* relaxation rate mapping have demonstrated increased iron deposition in the substantia nigra of patients with idiopathic Parkinson's disease (PD).

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 ...

Neuroimaging of Parkinson's disease by quantitative susceptibility mapping

NeuroImage
Parkinson's disease (PD) is a common neurodegenerative disease, and apart from a few rare genetic causes, its pathogenesis remains largely unclear. Recent scientific interest has been captured by the involvement of iron biochemistry and the disruption of

Thin slab quantitative susceptibility mapping

Magnetic Resonance in Medicine, 2023
AbstractPurposeSusceptibility maps reconstructed from thin slabs may suffer underestimation due to background‐field removal imperfections near slab boundaries and the increased difficulty of solving a 3D‐inversion problem with reduced support, particularly in the direction of the main magnetic field.

Functional quantitative susceptibility mapping (fQSM) [PDF]

NeuroImage, 2014
Blood oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) is a powerful technique, typically based on the statistical analysis of the magnitude component of the complex time-series. Here, we additionally interrogated the phase data of the fMRI time-series and used quantitative susceptibility mapping (QSM) in order to ...
