Research Interests

A.  Advanced Magnetic Resonance Imaging (MRI) and other molecular imaging techniques in Neurological Diseases
1. Alzheimer’s and other neurodegenerative diseases – Volumetric MRI, functional MRI, MR perfusion (Arterial Spin Labeling), susceptibility-weighted imaging (SWI) and MR spectroscopy
2. Brain trauma – Diffusion Tensor Imaging (DTI) in head trauma
3. Brain tumors - surrogate markers in anticancer drug trials using Dynamic Contrast Enhanced (DCE) MR perfusion, MR spectroscopy and Chemical Exchange Saturation Transfer (CEST)
4. Epilepsy- Positron Emission Tomography/Computed Tomography (PET/CT) and Volumetric MRI
5. Neuroeconomics – functional MRI

B. Stroke and Cardiovascular imaging
1. Stroke imaging – MR/CT perfusion imaging in evaluation of stroke, MRA/CTA in aneurysm screening and intracranial atherosclerosis, DTI in hemorrhagic stroke
2. Carotid plaque characterization- MRI
3. Evaluation of vascular risk factors using CT- calcium score and coronary CTA
4. Stem cell transplant imaging in Chronic Ischemic Stroke

C. Head and Neck Imaging
Multi-modality imaging in nasopharyngeal carcinoma- PET-CT and MRI perfusion/diffusion
