RADIOLOGY WEBSITES : FUNCTIONAL MRI WEBSITES

Few Useful Functional MRI Websites

1. fMRI Basics is an online educative material from the Deutsches Krebsforschungszentrum Cancer Centre at Heidelberg. Authored by Heiko Meyer and available from http://www.dkfz-heidelberg.de/mrphys/fmri/hmeyer/fmri_basics/start.html, the material has sections covering Human brain, Methods for mapping neuronal activity, BOLD-effect, Physiological effect, Physical effect, Pulse sequences and Statistical methods.

2.
fMRI for Dummies is an educative gateway authored by Jody Culham. The material is available at http://defiant.ssc.uwo.ca/Jody_web/fmri4dummies.htm and provides an introduction to fMRI, offering ideas on design and analysis, and acting as a reference. The material is available in the form of handouts in Adobe Acrobat PDF or slides in Microsoft PowerPoint and topics covered includes fMRI for Newbies, Basics of MRI and fMRI, Data Quality, fMRI Analysis, Experimental Design, Event-Related Designs, Cortical Neuroanatomy, Localizing Activation, and Surfaces and Topographic Mapping, A Primer on Cortical Sulci

3. Elementary functional MRI Data Analysis: A User's Manual
by Nick Szumski and Michael Rotte, MGH NMR Center is available online at http://www.nmr.mgh.harvard.edu/fmrianalysis/index.html. Sections on Scanning offer a rough overview of fMRI scanning procedures, while Step-by-step processing and Talairach mapping instructions is also covered.

4. Introduction to fMRI is a educative primer on Functional MRI, authored by Mark S Cohen & Susan J Bookheimer from the UCLA Brain Mapping Division Los Angeles, CA This article available at http://airto.bmap.ucla.edu/BMCweb/SharedCode/TINS/FMRI-TINS.html, originally published in "Trends in Neurosciences" can be easily considered as containing the essence of FMRI.

5. Foundations of fMRI throws the spotlight on FMRI. This educative material sourced from Duke University, Durham, USA is accessible at http://www.ee.duke.edu/~jshorey/MRIHomepage/fmri.html. The site covers interesting topics like History of MRI, How MRI Works, Functional MRI, fMRI Imaging Techniques. Besides all this there are images of MRI Fly-Through of Human Brain and one can visualise the unique experience of the Unfolding of cortical surface of the brain.

6.
Oxford Centre for Functional Magnetic Resonance Imaging of the Brain (FMRIB) is accessible at http://www.fmrib.ox.ac.uk/physics/. There are various educative sections on fMRI featured in this portal. Indeed, a good starting point is the section on 'Introduction to fMRI' at http://www.fmrib.ox.ac.uk/fmri_intro/ that establishes FMRI Applications and focuses on FMRI physiology. There are links to educational lectures available on k-space lecture, Intro to fMRI, Basic Physics of fMRI, Basic Physiology of fMRI and BOLD Imaging Sequences, all available at http://www.fmrib.ox.ac.uk/physics/.

7.
Functional Magnetic Resonance Imaging (fMRI) for the Psychiatrist is authored by J P Lorberbaum et al from the Medical University of South Carolina. Available at http://www.musc.edu/psychiatry/fnrd/primer_fmri.htm, the educative material concisely throws the spotlight on the basic concepts behind the main functional MRI techniques for imaging the brain.

8. Echo-planar imaging (EPI) and functional MRI is a primer authored by Mark S. Cohen, Ph.D. The material available at http://airto.loni.ucla.edu/BMCweb/BMC_BIOS/MarkCohen/Papers/EPI-fMRI.html is a concise and excellent summary of this exciting offshoot of MRI. The topics include What is EPI? , SNR, Bandwidth and Artifacts, Resolution, Hardware Requirements, dB/dt and Safety and Head Gradients, Contrast Variants and Volume EPI.

9. Functional MRI accessible at http://www.functionalmri.org/ has numerous sections linking to Journals, Brain atlases, Tutorials and | Software. This site's handy Atlas section links to nearly 28 Neuroanatomy Atlases, at the moment, some of them which include Virtual hospital: The human brain, Brodmann map, The Talairach Daemon and The Whole Brain Atlas.

10. Magnetic Resonance and Image Analysis Research Centre (MARIARC) is a centre based in United Kingdom focusing on experiments and analyse structural and functional MRI datasets. The website at http://www.mariarc.liv.ac.uk/ offers educative posters on FMRI depicting a wide range of paradigms and protocols, with various psychiatry and neuromapping applications.

A Primer o
n MRI and fMRI authored by from Douglas C. Noll, Associate Professor of Biomedical Engineering and Radiology Co-Director, Functional MRI Laboratory at the University of Michigan is available along with other assorted educative material at http://www.eecs.umich.edu/~dnoll/ .

Similarly, a concise article on fMRI titled About Functional MRI is available at http://www.fmri.org/fmri.htm. Sourced from the fMRI Research Center, Center for Neurobiology and Behavior, Columbia University, New York, the portal offers additional educative material in the form of archived lectures / presentations at http://www.fmri.org/lect.htm and an attention-grabbing section on Media and fMRI at http://www.fmri.org/media.htm.
