WEBSITES : MRI
Useful Websites on MRI
Interactive course about MRI physicsa at
http://www.e-mri.org/ is a web site putting the spotlight on the basic principles
of MRI. It is fashioned by Denis Hoa, Antoine Micheau, Gerald Gahide at Campus
Medica. Its content is interactive, with animations, experiments, and quizzes,
that enable easy learning MRI physics! This site is free of charge and no registration
is required.Educative sections dealing with Nuclear Magnetic Resonance,Basic principles,
Magnetic field gradients, Fourier Transform 2D, Image Quality and Artifacts, and
Image quality. Expected in 2006/2007, are sections planned for Fat signal suppression,
3D imaging,Flow imaging, Diffusion imaging, Functional MRI, Parallel imaging,
MRI Contrast Agents and MR Spectroscopy
of MRI at http://www.cis.rit.edu/htbooks/mri/inside.htm
is an online textbook written by JP Hornak from the Rochester Institute of Technology.
This textbook designed for the medical student and Radiology professionals, has
14 chapters covering the mathematics of MRI, spin physics, basic imaging techniques
and hardware. Sections on image artifacts and advanced imaging techniques are
also featured. Multimedia features like animated graphics richly supplement the
text. Besides all this, a handy glossary and a index of symbols are also available.
Physics put Simply at http://simplyphysics.com
deals online with a basic account of the physics related to MR Imaging. What's
more, this website has a Shockwave movie on MRI-Basics with a colorful, animated
introduction to the basic principles of MRI. Also available is from this site
is a guide to Cardiac MRI.
Acronym Registration Service is available at
Acronyms have been the bane of MR. To mitigate this very problem, the MARS
site (as it is popularly called) deals with the basic concepts and a brief
description of a large number of acronyms currently used in MR. The acronyms are
alphabetically arranged and a diagrammatic description is available for most MRI
Safety is available at http://www.mrisafety.com/.
This site developed and maintained by F.G. Shellock provides up-to-date information
on MRI safety-related topics. Impressively, latest information is provided for
screening patients with implants, materials, and medical devices. A key feature
of the site is the List, which is a searchable database that contains over
600 implants and other objects tested for MRI Safety. Moreover, there is a summary
section, which is a presentation of over 100 peer-reviewed articles on MRI bioeffects
and safety. There is also a CME section that provides articles and tests on MRI
page at http://kanal.arad.upmc.edu/MR_Safety/ is a database of Safety related
issues. The site crafted and fashioned by Emanuel Kanal, Director, Clinical and
Educational MR at University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania
has a searchable database by virtue of a a search engine as an added feature.
Useful URLs within the site include http://radserv.arad.upmc.edu/MR_Safety/mrsearch.html
and Information on Magnetic Resonance Imaging
is a website dealing with important topics in MRI. This is a short list of reference
papers at Readings in MRI section. Similarly, basic MR physics, basics of functional
MR Imaging and determinants of MR image quality are the other material available.
An article, "introduction to rapid MR imaging" reviews the techniques, applications
of rapid MRI imaging. For the MRI diehards there is a technical (implying mathematical!)
paper on motion compensation in MR imaging.
Home of EPI and Slice Selection at http://www.magres.nottingham.ac.uk/
is the website focussing on the development of the techniques and hardware
of MRI, particularly echo-planar imaging Interestingly, the group has been responsible
for many developments in the history and evolution of MRI.
MRI at http://www.users.on.net/vision/index.htm
is an admirable collection of web base resources on MRI issues prepared by Greg
Brown. The site is a comprehensive MRI portal catering to a variety of topics
within the speciality of MRI, covering sections such as MRI professional societies,
MR education resources, MR manufacturers pages, MRI papers, downloadable documents
and MRI Safety links.
http://www1.stpaulshosp.bc.ca/stpaulsstuff/MRartifacts.html is an illustrative
presentation on artifacts encountered in MR Imaging. The compilation of MR Artefacts
by Patola W & Coulter B from St. Paul's Hospital at Vancouver, portrays nearly
40 artifacts as images with descriptive text.
stylish and concise download of Basic MRI physics is available from Siemens
This is a useful item for students who are just beginning to grasp the fundamentals
of MR physics. Similarly, Basic Magnetization Physics as a central theme
is available in a text material at http://spinwarp.ucsd.edu/basicmr/BasicMRPhysics.html.
A Primer on Medical Device Interactions with MRI
Systems is available at http://www.fda.gov/cdrh/ode/primerf6.html.
