Approximately ⅓ of COVID-19 patients have shown neurological symptoms like headache, an altered mental state, acute cerebrovascular disease, and epilepsy. STAGE can be used to detect vascular damage and hemorrhagic lesions in the brain with greater detail than standard methods…

Visualizing the lateral habenula using susceptibility weighted imaging and quantitative susceptibility mapping
The habenulae consist of a pair of small nuclei which bridge the limbic forebrain and midbrain monoaminergic centers. They are implicated in major depressive disorders due to abnormal phasic response when provoked by a conditioned stimulus.
Imaging the Nigrosome 1 in the substantia nigra using susceptibility weighted imaging and quantitative susceptibility mapping: An application to Parkinson’s disease
The purpose of this study was to create a robust high quality, rapid imaging protocol, determine a slice by slice characterization of the appearance of N1 (the “N1 sign”) and evaluate the loss of the N1 sign in order to…
Longitudinal Magnetic Resonance Imaging of Cerebral Microbleeds in Multiple Sclerosis Patients
We hypothesized that cerebral microbleeds (CMBs) in multiple sclerosis (MS) patients will be detected with higher prevalence compared to healthy controls (HC) and that quantitative susceptibility mapping (QSM) will help remove false positives seen in susceptibility weighted imaging (SWI).
Semi-automatic detection of increased susceptibility in multiple sclerosis white matter lesions imaged with 1.5T MRI
The aims of this study were: 1) to define and validate a semi-automatic method for detecting RoIS in WML from quantitative susceptibility maps (QSM) and susceptibility-weighted imaging (SWI) acquired with a 1.5 T MRI scanner; 2) to assess the prevalence of…
Optimizing neuromelanin contrast in the substantia nigra and locus coeruleus using a magnetization transfer contrast prepared 3D gradient recalled echo sequence
Neuromelanin (NM) loss in the substantia nigra (SN) and locus coeruleus (LC) is being investigated as an imaging biomarker for Parkinson’s disease (PD) using magnetization transfer contrast (MTC) magnetic resonance imaging. The goal of this paper was to optimize the…
Vascular, flow and perfusion abnormalities in Parkinson’s disease
Reduced flow into the brain or decreased jugular venous outflow from the brain may serve as a potential biomarker for Parkinson’s disease (PD). Our goal was to compare the presence of vascular abnormalities, flow, and increases in midbrain iron content…
Susceptibility and Volume Measures of the Mammillary Bodies Between Mild Cognitively Impaired Patients and Healthy Controls
The purpose of this study was to investigate the baseline values and differences for susceptibility and volume of the mammillary bodies between mild cognitively impaired (MCI) patients and healthy controls (HCs), and further explore their differences in relation to gender,…
