The online database MR - Technology Information Portal ( was reviewed earlier in the Aug 2007 issue of this journal. Recently, a similar online database covering ultrasonography, titled UltraSound - Technology Information Portal is on offer at . "is a global information resource aimed at people with professional interests in medical ultrasound technology for imaging and/or therapy.", at its home page, links to a US-TIP Resource-Database that contains currently around 1600 entries. Within this are absorbing sections on UltraSound Technology, Knowledge 3D and 4D UltraSound, Contrast Agents, various examinations, History of UltraSound, Image Quality Artifacts, Probes Transducers and UltraSound Physics. Relevant to the topic of this web review, from the above two information portal sites, contrast agents is covered at  and .

EduRad at  is an online initiative aimed at integrating and improving the education of Radiologists by using a professional approach towards the organization of academic programs.Created by Dr. Bharat Parekh, Dr. Deepak Patkar and Dr. Jignesh Thakkar, the portal offers a wide range of web-based education for radiologists. After a mandatory registration, the website offers educative material on Case Reports, Image Gallery, Techno Watch, Classifieds, CME Events , Archives, Teaching Files, Radiology Learning Centre, Online Lectures and Past Conferences (Archives) ,Live Webcast-Interactive and DMRE (Part-I) lecture series on power point.

A Wiki is a special type of web site that enables a group of users to collectively edit, expand, revise, and create content. Wikipedia at  is a free encyclopedia of information created with a notable difference, in that, anyone can edit the information and therefore participate to create an online collaborative reference. What's more, the edited material is assessed for quality and verity by a "behind the scene" moderator group comprising of experts and voluntary professionals.

Medical Wikis are the medical equivalent of Wikipedia. They are hosted with an aim to offer comprehensive, veritable and up-to-the-minute information from a single point and that too on a large scale. Medical Wikis are emerging on the net as this List of Medical Wikis at  suggests. How far would they evolve and progress, what innovative features would they offer a decade from now, what are the advantageous spinoffs emerging from such websites and what is the endpoint in such websites are some of the hazardous questions that mystifyingly stare at us.

Nevertheless, when it comes to the discipline of radiology, the following Radiology Wikis are available at the moment:

  1. RadiologyWiki at . This site has a radiology image search functionally similar to ARRS Goldminer, Yottalook and Google image search. Titled Ajax, this filtered radiology image search engine is available at .
  2. RadsWiki at . This site has many sections, including those on named fractures, radiology in movies, differential diagnosis and a list of signs in radiology.
  3. Diagnostic Radiology Wikibooks is an open-content textbook collection at .
  4. wikiRadiography at  is an radiography resource on the web with sections on Applied Radiography written by M. J. Fuller, General Radiography, Computed Tomography, U/S, MRI and Mammography Homepages.
