We interviewed Stephen Correia, Ph.D., ABPP-CN, a neuropsychologist with extensive research and clinical training in the use of imaging techniques. In this episode, we cover clinical neuroimaging, with a focus on computed tomography (CT) and magnetic resonance imaging (MRI) techniques.

- The centrality of patient care in making clinical decisions related to neuroimaging
- Factors to consider when thinking about examining multiple brain scans in a single patient
- Brief definitions of basic terminology, including the following topics:
- Common neuroimaging techniques
- Anatomical planes
- Orientation of scans
- Contrast material
- Basic brain pathology
- White matter pathology
- Diffusion weighted imaging (DWI) and its relationship to diffusion tensor imaging (DTI)
- The basics of DTI (including tractography) – its underlying structure, its utility, and its limitations
- Whether neuroimaging is a threat to neuropsychology in the 21st century
- Whether further advancements in neuroimaging could make neuropsychology obsolete
Steve earned his Ph.D. in Clinical Psychology at the University of Rhode Island. He completed his pre-doctoral internship at the Malcolm Randall VA Medical Center in Gainesville Florida. He then returned to Rhode Island where he completed a clinical neuropsychology fellowship at Brown University under the mentorship of Drs. Paul Malloy and Stephen Salloway at the Butler Hospital Memory and Aging Program. Steve then completed a T32 Research Fellowship in Neuropsychology also in the Memory and Aging Program. Steve is currently Associate Professor in the Department of Psychiatry and Human Behavior in the Alpert Medical School of Brown University. He is the Neuropsychology Section Chief at the Providence VA Medical Center and is the Director of Brown’s Clinical Neuropsychology Specialty Program for Postdoctoral Training. Steve’s research focuses on using diffusion tensor imaging to examine the cognitive and behavioral correlates of white matter integrity in aging, dementia, and other conditions.
