Welcome to the Tivarus Lab
Our research focuses on clinical applications of advanced neuroimaging techniques such as functional MRI (fMRI), MR Spectroscopy (MRS), Diffusion Tensor Imaging (DTI), morphometry, Arterial Spin Labeling (ASL) and Dynamic Susceptibility Contrast (DSC). We have been using these techniques to study patients with brain tumors, epilepsy, Alzheimer’s disease, HIV associated neurocognitive impairment, multiple sclerosis.
