Quantitative Susceptibility Mapping: Concepts and Applications
Clinical Neuroradiology, 2015To review the fundamental principles of susceptibility-weighted imaging (SWI) and quantitative susceptibility mapping (QSM), and to discuss recent clinical developments.SWI is a magnetic resonance imaging method that takes advantage of magnitude signal loss and phase information to reveal anatomic and physiologic information about tissue and venous ...

Tilted quantitative susceptibility mapping at oblique MRI (tiltQSM)
Computers in Biology and Medicine, 2023If the phase image matrix was acquired from oblique MRI, it is needed to deal with the oblique effect for quantitative susceptibility mapping (QSM), as addressed in this paper.We proposed two methods for QSM reconstruction from slice-tilted MRI phase image (tiltQSM): 1) rotData per anti-tilting phase image rotation back into the B0-upright system, and ...

Quantitative Susceptibility Mapping: Basic Methods and Clinical Applications
RadioGraphics, 2022Quantitative susceptibility mapping (QSM), one of the advanced MRI techniques for evaluating magnetic susceptibility, offers precise quantitative measurements of spatial distributions of magnetic susceptibility. Magnetic susceptibility describes the magnetizability of a material to an applied magnetic field and is a substance-specific value.

Rapid quantitative susceptibility mapping of intracerebral hemorrhage
Journal of Magnetic Resonance Imaging, 2019BackgroundQuantitative susceptibility mapping (QSM) offers a means to track iron evolution in hemorrhage. However, standard QSM sequences have long acquisition times and are prone to motion artifact in hemorrhagic patients.PurposeTo minimize motion artifact and acquisition time by performing rapid QSM in intracerebral hemorrhage (ICH) using single‐shot

Value of Quantitative Susceptibility Mapping in Clinical Neuroradiology
Journal of Magnetic Resonance Imaging, 2023Quantitative susceptibility mapping (QSM) is a unique technique for providing quantitative information on tissue magnetic susceptibility using phase image data. QSM can provide valuable information regarding physiological and pathological processes such as iron deposition, hemorrhage, calcification, and myelin.

Image Reconstruction in Quantitative Susceptibility Mapping
SIAM Journal on Imaging Sciences, 2016Summary: This paper deals with a reconstruction problem in magnetic resonance imaging where the Fourier transform of the sought-for object can't be obtained in the vicinity of a cone-shaped surface. This leads to streak-shaped artifacts in the sagittal views of the object.

Quantitative susceptibility mapping differentiates between parkinsonian disorders
Parkinsonism & Related Disorders, 2017It is often challenging to clinically distinguish between Parkinson's disease (PD), multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). Quantitative susceptibility mapping (QSM) is an accurate indirect method for estimating brain iron levels in vivo. This method has yet to be applied in atypical parkinsonism. We aimed to investigate

Sparse methods for Quantitative Susceptibility Mapping
SPIE Proceedings, 2015Quantitative Susceptibility Mapping (QSM) aims to estimate the tissue susceptibility distribution that gives rise to subtle changes in the main magnetic field, which are captured by the image phase in a gradient echo (GRE) experiment. The underlying susceptibility distribution is related to the acquired tissue phase through an ill-posed linear system ...

Quantitative trait locus mapping for atherosclerosis susceptibility
Current Opinion in Lipidology, 2003Atherosclerosis is a complex trait with both environmental and genetic aspects. Although some progress has been made in defining genes associated with atherosclerosis in humans, animal models have been useful in learning about pathways and genes involved in atherogenesis.
