Neuroimage Processing

Neuroimage ProcessingModern medical imaging provides a wealth of information, using multiple imaging techniques. This is particularly true of neuroimaging, where a number of novel MRI methods have been developed to investigate brain structure and connectivity. Our focus is on the integration of multiple imaging modalities, including magnetic resonance (MR) and positron emission tomography (PET), in order to identify neural patterns related to Alzheimer’s disease, successful cognitive aging, and fatigue. This includes the analysis of structural MR, as well as diffusion tensor imaging (DTI). The goals of these projects are to identify imaging biomarkers that would allow for earlier diagnosis and improved treatment of Alzheimer’s, and to identify neural correlates of successful cognitive aging and fatigue. This work is highly collaborative, involving Dr. Feng Lin from the School of Nursing and Dr. Zhengwu Zhang from the Department of Biostatistics and Computational Biology.
