Quantitative Susceptibility Mapping for Following Intracranial Hemorrhage [PDF]

Radiology, 2018
Purpose To follow the evolution of intracranial hemorrhage (ICH) by using quantitative susceptibility mapping (QSM). Materials and Methods Thirty-six patients with ICH confirmed at CT were enrolled to follow ICH evolution on day 2, 7, and 30 after symptom onset between August 2013 and April 2017.

Parkinson’s disease or multiple system atrophy: potential separation by quantitative susceptibility mapping

Therapeutic Advances in Neurological Disorders, 2023
Background: Due to the absence of robust biomarkers, and the low sensitivity and specificity of routine imaging techniques, the differential diagnosis between Parkinson’s disease (PD) and multiple system atrophy (MSA) is challenging.

Reducing Streaking Artifacts in Quantitative Susceptibility Mapping [PDF]

SIAM Journal on Imaging Sciences, 2017
It is well-known that reconstruction algorithms in quantitative susceptibility mapping often contain streaking artifacts. In [1], the cause of the artifacts is identified as propagation of singularities. In this work, we analyze such singularities carefully and propose some strategies to reduce the artifacts.

Improved Visualization of Cartilage Canals Using Quantitative Susceptibility Mapping. [PDF]

PLoS ONE, 2015
Cartilage canal vessels are critical to the normal function of epiphyseal (growth) cartilage and damage to these vessels is demonstrated or suspected in several important developmental orthopaedic diseases.

Thrombus magnetic susceptibility is associated with recanalization and clinical outcome in patients with ischemic stroke

NeuroImage: Clinical, 2022
In acute ischemic stroke patients with large vessel occlusion, the characteristics of the occluding thrombus on neuroimaging may be associated with recanalization after endovascular thrombectomy (EVT); however, the relationship between magnetic ...

Methods for quantitative susceptibility and R2* mapping in whole post-mortem brains at 7T applied to amyotrophic lateral sclerosis

NeuroImage, 2020
Susceptibility weighted magnetic resonance imaging (MRI) is sensitive to the local concentration of iron and myelin. Here, we describe a robust image processing pipeline for quantitative susceptibility mapping (QSM) and R2* mapping of fixed post-mortem ...
