MR imaging findings in mild traumatic brain injury with persistent neurological impairment
Magnetic resonance imaging provides objective biomarkers in the diagnosis of brain injury by detecting brain lesions resulting from trauma. This paper reports on the detection rates of presumed trauma-related pathology using fluid-attenuated inversion recovery (FLAIR) and susceptibility-weighted imaging (SWI) in…

Cerebral Microbleeds in Multiple Sclerosis Evaluated on Susceptibility-weighted Images and Quantitative Susceptibility Maps: A Case-Control Study
The purpose of this study was to assess cerebral microbleed (CMB) prevalence in patients with multiple sclerosis (MS) and clinically isolated syndrome (CIS) and associations with clinical outcomes.
Assessing Global and Regional Iron Content in Deep Gray Matter as a Function of Age Using Susceptibility Mapping
The purpose of this study was to investigate the correlation of non‐heme iron content in deep gray matter nuclei as a function of age using quantitative susceptibility mapping (QSM) from both whole‐structural and regional perspectives.
Determination of detection sensitivity for cerebral microbleeds using susceptibility- weighted imaging
This study provides a comprehensive analysis of the number of voxels detected in the presence of a CMB on GE magnitude, phase and SWI composite images as a function of resolution, signal‐to‐noise ratio (SNR), TE, field strength and susceptibility using…
Cerebral Hemodynamic Changes of Mild Traumatic Brain Injury at the Acute Stage
Mild traumatic brain injury (mTBI) is a significant public health care burden in the United States. However, we lack a detailed understanding of the pathophysiology following mTBI and its relation to symptoms and recovery. With advanced magnetic resonance imaging (MRI),…
Quantitative susceptibility mapping: current status and future directions
Quantitative susceptibility mapping (QSM) is a new technique for quantifying magnetic susceptibility. It has already found various applications in quantifying in vivo iron content, calcifications and changes in venous oxygen saturation. The accuracy of susceptibility mapping is dependent on several…
Quantitative measurements of brain iron deposition in cirrhotic patients using susceptibility mapping
The purpose of this study was to compare the susceptibility of different brain structures in cirrhotic patients with that in healthy controls and to evaluate susceptibility as a potential biomarker and correlate the measured susceptibility and cadaveric brain iron concentration…
Decreased oxygen saturation in asymmetrically prominent cortical veins in patients with cerebral ischemic stroke
Decreased oxygen saturation in asymmetrically prominent cortical veins (APCV) seen in ischemic stroke has been hypothesized to correlate with an increase of de-oxygenated hemoglobin. Our goal is to quantify magnetic susceptibility to define APCV by establishing a cutoff above which…
