Prediction of early neurological deterioration using quantitative susceptibility mapping in small artery occlusion ischemic stroke

IBRO Neuroscience Reports
Background: Approximately 20–30% of ischemic stroke patients with small artery occlusion (SAO) experience early neurological deterioration (END) after stroke onset, which is associated with a poor prognosis.

Ex-vivo quantitative susceptibility mapping of human brain hemispheres.

PLoS ONE, 2017
Ex-vivo brain quantitative susceptibility mapping (QSM) allows investigation of brain characteristics at essentially the same point in time as histopathologic examination, and therefore has the potential to become an important tool for determining the ...

Exploring domain adaptation for deep neural network trained QSM

, 2022
Quantitative susceptibility mapping (QSM) is a MRI technique that estimates tissue magnetic susceptibility. The generation of QSM requires solving a challenging ill-posed field-to-source inversion problem.

Harmonic field extension for QSM with reduced spatial coverage using physics-informed generative adversarial network

NeuroImage
Quantitative susceptibility mapping (QSM) is frequently employed in investigating brain iron related to brain development and diseases within deep gray matter (DGM). Nonetheless, the acquisition of whole-brain QSM data is time-intensive.

Partial volume correction for quantifying venous oxygen saturation levels using contrast-enhanced MRI

NeuroImage
Quantifying brain oxygenation is crucial for diagnosing and managing neurological conditions like stroke. Quantitative susceptibility mapping (QSM), an MRI technique, can measure venous oxygen saturation (Yv) but is hampered by partial volume effects ...
