Description of Research Expertise

I am primarily interested in the imaging of acute and chronic cerebrovascular disease. The immediate goal of current projects is to gain a better understanding of carotid atherosclerosis and its relationship to stroke using structural MR and CT techniques. The long-term goal is to integrate structural imaging of the brain and extracranial and intracranial blood vessels with functional imaging methods of the brain, including perfusion-weighted imaging (PWI), diffusion-weighted and diffusion tensor imaging (DWI and DTI), functional MRI (fMRI), and/or spectroscopy in order to generate a comprehensive exam for the evaluation of cerebrovascular disease. I have a particular interest in perfusion imaging of the brain using a variety of techniques, including bolus contrast CT and MR perfusion, stable xenon CT perfusion, and arterial spin labeled (ASL) perfusion imaging. This interest targets not only cerebrovascular disease but also nonischemic pathology, especially CNS neoplasms and associated treatment effects.

Description of Itmat Expertise

Recent efforts are focused on studies of CNS neoplasia, vascular malformations and brain ischemia. Translation of initially primarily research tools like CT and MR perfusion, fMRI and more recently DTI/tractography into routine clinical practice is also a primary goal.
