Technical considerations for using intravenous gadolinium-based-contrast-agent (GBCA) based MRI approaches to study cerebrospinal fluid (CSF) circulation and clearance Open
Intravenously (IV) administered Gadolinium-based-contrast-agents (GBCAs) can enter the intracranial cerebrospinal-fluid (CSF) space via weak barriers between blood and CSF at multiple locations in the brain. This enables IV-GBCAs to be use…
Diffusion Tensor Imaging in Neurofluids Open
In this review article, we describe the development and application of diffusion-based MR imaging methods for studying glymphatic physiology. Fluid exchange and solute transport are the 2 key components of the glymphatic system. Here we de…
Comparison and optimization of <span>pCASL</span> and <span>VSASL</span> for rat thoracolumbar spinal cord <span>MRI</span> at 9.4 T Open
Purpose To evaluate pseudo‐continuous arterial spin labeling (pCASL) and velocity‐selective arterial spin labeling (VSASL) for quantification of spinal cord blood flow (SCBF) in the rat thoracolumbar spinal cord. Methods Labeling efficienc…
Differential Trajectory of Diffusion and Perfusion Magnetic Resonance Imaging of Rat Spinal Cord Injury Open
Traumatic spinal cord injury causes rapid neuronal and vascular injury, and predictive biomarkers are needed to facilitate acute patient management. This study examined the progression of magnetic resonance imaging (MRI) biomarkers after s…

King-Devick Sensitivity and Specificity to Concussion in Collegiate Athletes Open
Context The King-Devick (K-D) test is used to identify oculomotor impairment after concussion. However, the diagnostic accuracy of the K-D test over time has not been evaluated. Objectives To (1) examine the sensitivity and specificity of …
Diffusion‐prepared fast spin echo for artifact‐free spinal cord imaging Open
Purpose Diffusion MRI provides unique contrast important for the detection and examination of pathophysiology after acute neurologic insults, including spinal cord injury. Diffusion weighted imaging of the rodent spinal cord has typically …

Optimized cervical spinal cord perfusion MRI after traumatic injury in the rat Open
Despite the potential to guide clinical management of spinal cord injury and disease, noninvasive methods of monitoring perfusion status of the spinal cord clinically remain an unmet need. In this study, we optimized pseudo-continuous arte…
Effects of High-Dose Vitamin D2 Versus D3 on Total and Free 25-Hydroxyvitamin D and Markers of Calcium Balance Open
D3 increased total and free 25D levels to a greater extent than D2. Free 25D may be superior to total 25D as a marker of vitamin D bioactivity.
