Elster AD. Questions and answers in MRI. MRI Questions Web site. http://mriquestions.com/index.html.

For radiologists who have devoted their lives and education to medical diagnosis, trying to grasp the advanced physics behind modern MR imaging is like a foray into another world with a completely exotic language. Resources and texts are numerous, but many are written by those who primarily have a formal physics education and write in a language unfamiliar to those without the same background. Out of all the available resources, one shining beacon lights the path to understanding.

With his website mriquestions.com, Dr. Allen Elster, MD, FACR translates the language of MR imaging, beautifully explains complex concepts, and simply transforms the foreign into the familiar. Whenever I have a question about the physics of MR imaging as it relates to my daily radiology practice, I consult the website and almost always have an answer within 5 minutes of reading. While covering numerous topics in MR imaging, Dr. Elster strives to fill each article with practical information that is applicable to optimizing patient imaging. This is why his website stands out among all the others; he is able to take the complexity of MR imaging and distill the information to that which is most valuable for the daily practicing radiologist. Included at the end of each page are references, many of which are interesting historic and landmark papers in the development of MR imaging.

The site design is beautifully practical and it often feels as though he has anticipated the next questions of the reader and placed links to relevant information. All content is free to use and frequently updated with new sections.

The next time a question arises in the reading room about the principles behind an MR imaging sequence, the cause of an artifact, or the best way to optimize a patient image, look no further than mriquestions.com for the answer.
