Few Useful MRI Angiography Websites

1. A premier website on MR Angiography is available at http://www.mrprotocols.com/. Authored by Martin R. Prince, MD, PhD, the leading global expert on CEMRA, the MRA protocols are evidently the current standard references. The website has comprehensive educative material on MRA covering topics like Principles of 3 D Gadolinium MRI, MRA Protocols, MRI Protocols, Download MRI and MRA Lectures and Protocols at Columbia College of Physicians and Surgeons, New York

Educative material on MR Angiography and its varied applications are available at Topspins.Com. The MRA related downloads are available as a special feature at on http://www.topspins.com/download/download.html. The material covers Renal, Peripheral vascular, Abdominal Aortic Aneurysm, Dilute Gadolinium Venography, Pulmonary, Mesenteric-Portal, Bolus Chase 3D:MRA, Renal Artery Stenosis, Renal Transplant and Mesenteric MRA.

A Brief Overview on Magnetic Resonance Angiography from Greg Brown SMRT at Royal Adelaide Hospital is available online at http://www.users.on.net/vision/papers/basicMRA/MRA_Intro.htm . The material covers areas such as Factors affecting the appearance of flowing blood, Important characteristics of flow, Time of Flight and its Applications, Phase Contrast and its Applications. Besides all this, there are separate features on Flow Quantification and Contrast Enhanced MRA, its techniques.

4. From the University of Michigan Health Systems at http://www.med.umich.edu/rad/mribody/ are a series of educative material on MRI and MRA. Specifically, Portal and Mesenteric MR Angiography authored by William Weadock, M.D. is available at http://www.med.umich.edu/rad/mribody/portal/index.html and Renal MR Angiography at http://www.med.umich.edu/rad/mribody/renal/index.html. Portal and Mesenteric MR Angiography http://www.med.umich.edu/rad/mribody/portal/index.html

5. The UCSD Neuroradiology Teaching File Database is developed and authored by John R. Hesselink, MD, FACR. Sourced from Department of Radiology, University of California, San Diego, at http://spinwarp.ucsd.edu/NeuroWeb/ , it contains distinctive educative sections The JHess Collection, The Visiting Professor Series, Text Syllabus and Normal Anatomy Series. MR Angiography: Techniques and Applications is a comprehensive section available at http://spinwarp.ucsd.edu/NeuroWeb/Text/br-120.htm

6. Renal MR Angiography
is a special educative feature available at http://ej.rsna.org/ej3/0091-98.fin/index.html. The material authored by William Weadock, MD, from University of Michigan Medical Center, assists in learning the basic principles of gadolinium-enhanced MR angiography and renal MR angiography. It provides information for radiologists on principles of 3D gadolinium-enhanced MR angiography, selection of optimal imaging parameters, timing of the gadolinium bolus and evaluation of normal variants and common pathologic entities.

7. Basic Principles of Phase-contrast, Time-of-flight, and Contrast-enhanced MR Angiography
is a special feature available from American Association of Physicists in Medicine. Available at http://www.aapm.org/meetings/99AM/pdf/2847-56865.pdf , the material is authored by Frank R. Korosec, Ph.D, from the Department of Radiology and Medical Physics at University of Wisconsin - Madison

8. Horizons in Imaging Series and Essential Radiology Series are a set of courses developed and sponsored by Ithaca Center for Postgraduate Medical Education. MR Angiography is a popular and exciting topic featured in the series. Two such educative topics are
a) Peripheral MR Angiography: authored by Neil M. Rofsky, MD, Director, Body MRI from New York University Medical Center, available at http://www.radinfonet.com/cme/rofsky/rofsky.htm#cme_info , and
b) MRA of the Aortic Arch Vessels: an illustrative material authored by Glenn Krinsky, MD, Assistant Professor of Radiology , New York University Medical Center, available at http://www.radinfonet.com/cme/krinsky/krinsky_01.htm .

9. Educative material on MR flow velocity mapping is available at http://www.medis.nl/MainFrameProducts/Products/MriFlow/BrochureFLOW.htm. This new technique is particularly useful for the quantification of arterial and transvalvular blood flow. MR Flow Imaging- A Study of Flow Effects on the Gradient Echo Sequence is a special feature available at http://www.sparta.lu.se/~jonas/exjobb/toc.html

10. Academic Radiology offers a special supplement devoted to Contrast (based on the Contrast Media Research (CMR) meetings) is available in the January 2002 (Vol. 9, Issue 1, Supplement) and February 2002 (Vol. 9, Issue 2, Supplement) , both accessible form http://www.academicradiology.org/issues/contents . It contains useful information on MR Angiography, as well as the applications and "cutting edge research" on many types of Contrast in various modalities. Incidentally, the CMR meetings had its origins in the 1960s by Elliott Lasser and other luminaries in the field of contrast agent research.


The International MR Angio Club at http://www.mr-angio.org/ is a dedicated portal focusing on improving patient care through the advancement of magnetic resonance angiography.

Ethan Brodsky's Magnetic Resonance Angiography Web Page at http://zoot.radiology.wisc.edu/home/ethan/html/ offers material on Time-Resolved MRA, Contrast-Enhanced Magnetic Resonance Angiography (CE-MRA) and has few movies offered in MPG format. ?

Gad-enhanced MRA: Aorta and Great Vessels is an educative feature authored by James P. Earls and is available at http://mri.cpson.com/pdf/Gad-enhanced_MRA_Aorta_and_great_Vessels.pdf
