Answers to In-frequently Asked PET Questions

When should we administer a dopaminergic stimulus relative to an injection of 11C-raclopride to get a maximal change in BP?










Evan D. Morris, PhD has been working in the field of PET and functional imaging  for 20 years.  He specializes in kinetic modeling of dynamic image data.  He was trained as a biomedical engineer and before that as a chemical engineer. In the past, he has taught courses at the undergraduate and graduate levels in Medical Imaging, Tracer Kinetics, Biomedical Transport, and Biomedical Ethics, among others. For more info about his past classroom teaching at Indiana University, Purdue University at Indianapolis (IUPUI), including online lectures (video and Powerpoints) for some courses, please follow the link to his IUPUI website.  Morris joined the Yale PET Center as Co-Director of the Imaging Section in the fall of 2009.

Dr Morris and his students have been working on kinetic models to estimate the dynamics of endogenous neurotransmitters from PET data.  A recent publication in Neuroimage in 2010 demonstrated a novel analysis strategy for creating the first ever “movies” of dopamine action in the living brain. The movies can be viewed here (movie of "early" finger-tapping, movie of "late" finger-tapping).  Altered neurotransmitter kinetics may explain the mechanism of addiction of some drugs.  This work  uses knowledge of numerical methods, biochemistry, image and signal processing, parameter estimation, and programming.  An earlier paper in Molecular Imaging and Biology compared the  estimates of dopamine curves from fitting models to PET data to direct microdialysis measurements.  A collection of papers to result from this project can be downloaded as a zip file here. (~8Mb)  The work was funded by the Whitaker Foundation and the National Institute on Alcohol Abuse and Alcoholism.

While in Indiana, Morris and his colleagues focused much of their efforts on the use of PET to understand what makes drugs and alcohol addictive.  Their most recent publication in Alcoholism, Clinical and Experimental Research in 2009 is here.  It represents the first demonstration in humans of the neurochemistry of reward prediction error.  This work uses knowledge of neuropsychology, image processing, experimental study design, neurochemistry, and kinetic modeling.

Prof. Morris is currently interested in the use of PET imaging (of people and animals) with neuroreceptor tracers to understand and improve treatments for Parkinson’s disease, alcoholism, smoking, drug abuse and cancer.


Current Active Projects (all use PET imaging and some type(s) of mathematical modeling)

Are kappa opiate receptors important for the treatment of alcoholism?  Are there sex-differences in the kappa receptor system?

Is there a brain pattern of dopamine activation in the brain that represents the signature of addiction to smoking cigarettes? (To marijuana?) (To other drugs of abuse?)

Are kappa antagonists viable medications for the treatment of depression?

What is the precise molecular target of the cancer drug erlotinib that is used to treat lung cancer? Can  we image the target and predict treatment outcome?

How is the pattern of dopamine activation in your brain during smoking altered by treatment?

Does stress add to the likelihood of relapse to smoking? Is dopamine the mediator of this effect?

Job Opportunities

1. Many opportunities for students to do research rotations.  If you are a BME student or an INP student and need a rotation, please email Dr Morris

Past interests of Prof Morris:

Small animal imaging. A recent paper details the design and validation of a stereotactic head-holder for imaging two rats in a PET scanner at the same time.  The paper was published in Journal of Neuroscience Methods. Get it here.

Direct reconstruction of PET data to parametric images.  This work was a collaboration with colleagues at Purdue University and used knowledge of kinetic modeling, imaging physics, optimization and algorithm design.  It yielded the first working algorithm to create parametric images of the four kinetic parameters of the two-tissue model directly from raw (sinogram) data.  The primary paper to result from this collaboration was published in IEEE Transactions on Medical Imaging and can be downloaded here.   A new publication  is currently "in press" in  IEEE TMI on this topic.
