[Freesurfer] VBM by freesurfer
External Email - Use Caution Hello, I am trying to run a VBM analysis by using the white matter and the grey matter masks from Freesurfer, because, often, other tools are not able to calculate a correct white matter and grey matter masks. When I have these masks, I have to apply them to my original T1 images. However, the original T1 is in different space. I can resample the ROIs (WM and GM) in order to apply them to my original T1, but my question is: Can I use the orig.mgz from Freesurfer as my T1 for VBM, or does it have different intensity from my real T1 acquisition? Thanks, Maurizio ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer

[Freesurfer] Postdoctoral Fellowship in advanced multi-parametric imaging in Parkinson’s disease, Alzheimer’s disease, and healthy aging
External Email - Use Caution My Lab, at Barrow Neurological Institute (Phoenix, AZ), is looking for a Postdoc. For more information email to: Ashley M. Stokes, Ph.D. Assistant Professor // Division of Neuro-Imaging Research Barrow Neurological Institute *ashley.sto...@barrowneuro.org* and/or Ryan R. Walsh, M.D., Ph.D., FAAN Associate Professor // Muhammad Ali Parkinson Center Department of Neurology // Barrow Neurological Institute *ryan.wa...@barrowneuro.org* A postdoctoral fellowship position (fully funded for up to three years) is available at Barrow Neurological Institute (BNI) working with Ashley Stokes, PhD, and Ryan R. Walsh, MD, PhD, as part of a rapidly growing collaborative research effort between the Division of Neuro-Imaging Research, Department of Neurology, and Muhammad Ali Parkinson Center. The position will primarily focus on the development, application, and analysis of advanced MRI methods in the context of both Parkinson’s disease and Alzheimer’s disease, as well as dementia with Lewy bodies and healthy cognitive aging, expanding upon recent novel approaches developed by this multi-modal lab. These methods include advanced functional, diffusion, perfusion, and structural imaging methods, with an emphasis on novel mathematical/signal processing approaches to provide a more comprehensive understanding of neurodegenerative diseases and normal brain aging across structural, functional, and perfusion signatures, including their mutual interdependence. BNI is the world’s largest dedicated neurological disease treatment and research institution, and the Muhammad Ali Parkinson Center at BNI is a recognized leader in the field. Outstanding institutional resources, including 1.5T and 3T Philips clinical MRI, a research-dedicated Philips 3T MRI, a 7T preclinical Bruker MRI, microCT, microPET, and optical imaging scanners are available at BNI. The Division of Neuro-Imaging Research has a strong history of imaging excellence and is currently expanding. BNI is a major hub for neuroscience research, including both basic and translational neuroscience, with a wide range of internationally-recognized neurology subspecialties. Barrow Neurological Foundation provides robust philanthropic support exceeding $18M per annum, 100% of which benefits patient care, research and education at BNI. Applicants should have a PhD in physics, engineering, mathematics, computer science, or a related discipline. Competitive candidates will have expertise in signal processing and/or functional MRI and be interested in developing novel approaches to analysis of MRI-based signals. This position is available immediately and offers competitive compensation and benefits. Phoenix is the 5th largest metropolitan in the United States and the 2nd fastest growing city. Phoenix is a beautiful place to live and work, boasting more days of sunshine and a lower cost of living than most comparable cities. A rich culture, including theatre, concerts, museums, sports, and great food, are easily found in Phoenix. With a moderate climate most of the year, many Phoenicians enjoy an active lifestyle of hiking, cycling, rock climbing, swimming, and golf. Interested applicants should send a current CV, including the names of three references, to both: *Ashley M.
