Cardiac quantitative susceptibility mapping (QSM) for heart chamber oxygenation [PDF]

open access: yesMagnetic Resonance in Medicine, 2018
PurposeTo demonstrate the feasibility of in vivo quantitative susceptibility mapping (QSM) in cardiac MRI and to show that mixed‐venous oxygen saturation (SvO2) can be measured non‐invasively using QSM.MethodsElectrocardiographic‐gated multi‐echo 2D gradient echo data were collected at 1.5 T from 14 healthy volunteers during successive breath‐holds ...

Quantitative susceptibility mapping (QSM) with an extended physical model for MRI frequency contrast in the brain: a proof‐of‐concept of quantitative susceptibility and residual (QUASAR) mapping [PDF]

open access: yesNMR in Biomedicine, 2018
Quantitative susceptibility mapping (QSM) aims to calculate the tissue's magnetic susceptibility distribution from its perturbing effect on the MRI static main magnetic field. The method is increasingly being applied to study iron and myelin in clinical and preclinical settings.

Quantitative susceptibility mapping (QSM) and R2* of silent cerebral infarcts in sickle cell anemia. [PDF]

open access: yesFront Neurol, 2022
Silent cerebral infarction (SCI) is the most commonly reported radiological abnormality in patients with sickle cell anemia (SCA) and is associated with future clinical stroke risk. To date, there have been few histological and quantitative MRI studies of SCI and multiple radiological definitions exist.

Quantitative susceptibility mapping (QSM) evaluation of infantile neuroaxonal dystrophy. [PDF]

open access: yesBJR Case Rep, 2019
We present the first case of twins with infantile neuroaxonal dystrophy evaluating brain iron deposition using quantitative susceptibility mapping (QSM). A 6-year-old boy who was normal at birth had psychomotor regression and hypotonia from 2-years-old.

Systematic Review: Quantitative Susceptibility Mapping (QSM) of Brain Iron Profile in Neurodegenerative Diseases. [PDF]

open access: yesFront Neurosci, 2021
Iron has been increasingly implicated in the pathology of neurodegenerative diseases. In the past decade, development of the new magnetic resonance imaging technique, quantitative susceptibility mapping (QSM), has enabled for the more comprehensive investigation of iron distribution in the brain.

Nonlinear dipole inversion (NDI) enables robust quantitative susceptibility mapping (QSM). [PDF]

open access: yesNMR Biomed, 2020
High‐quality Quantitative Susceptibility Mapping (QSM) with Nonlinear Dipole Inversion (NDI) is developed with pre‐determined regularization while matching the image quality of state‐of‐the‐art reconstruction techniques and avoiding over‐smoothing that these techniques often suffer from.
