I have just started my sixth and final clinical rotation in Neurology, that is why I was delighted to be notified about the latest Webicina package aimed at professionals.
Berci Meskó, author of Scienceroll and founder of Webicina put together another fantastic collection of Web 2.0 tools, this time in the field of Neurology.

My favorite is the collection of slideshows, which I am sure will help me prepare for my exam come the end of June.

You may find many more packages on Webicina aimed at patients and professionals as well.

Diagnostic Imaging 2.0: Communities December 14, 2008

Posted by tomography in Community sites, Diagnostic Imaging 2.0, web 2.0.
Tags: , ,

A sense of community is an essential need of ours, and online social communities have made it easier for us to connect to, and stay in touch with people who are either important to us or share similar passions to ours, or both. So if your area of interest is diagnostic imaging, these online communities may be for you.

In order to participate in most communities, you must first create your own login name and password. This is necessary because there must be a way to indentify you if you write on a discussion board, or send short intranetwork messages to other users, and most communities also allow you to start your own blog within that particular community which also has to be connected to at least a login name.

What can you do on social community sites?


  • to old friends from residency and medical school
  • to your next employer


  • Discuss, share, and see interesting cases with radiologists from around the world
  • Share your research ideas and establish a new collaboration
  • Find out the next time someone gives a lecture/CME on your area of interest

Get answers:

  • Discuss the latest topics and turf battles of radiology
  • Find another radiologist who can help with literally anything
  • Find a mentor or a mentee

1. RadRounds.com, short for Radiology Rounds, is the largest social network site for Radiologist created by Radiologists. It is very similar to Facebook, MySpace and the others, but on a professional level. So it is the Tiromed of Radiologists. Members are either medical professionals, medical students, technicians, or programmers, so they are all somehow related to the field of Radiology.

radRounds Radiology Network

2. RADiX.in : An Exclusive Online Radiology Community with over 2,200 registered members is the largest Radiology community in Asia, and the number 2 most visited Radiology community worldwide. It has a large collection of teaching files and videos.


3. Auntminnie.com is your Radiologist Aunt. “AuntMinnie provides a forum for radiologists, business managers, technologists, members of organized medicine, and industry to meet, transact, research, and collaborate on topics within the field of radiology with the ease and speed that only the Internet can provide. AuntMinnie features the latest news and information about medical imaging.”


4. Filmjacket.com is a website for all professionals affiliated with the field of radiology. You can post and browse radiology jobs, submit and read the latest radiology news, participate in discussion forums, read radiology-related articles and browse radiologic images and cases. Unfortunately Filmjacket is no longer available, but I will leave it in this list, because this was the very first community website dedicated to Radiology.


5. The object of CIDER is to contribute to the understanding of pulmonary radiology.  It includes an e-Book on the basic concepts of pulmonary radiology, a Tutorial Section, a Case of The Month Section, a Show and Tell Section, a Boards Primer Section and a Benefactors Section. QUIZZ/GAMING features that reinforce the various concepts you have learned are available when considered appropriate.

Ebay for Radiology: TeleRays October 23, 2008

Posted by tomography in Radiology, web 2.0.

The wait is over! Telerays enters the market. Telerays is essentially an auction-based system for delivery of radiology services, as some have already referred to as an Ebay for radiology and radiologists. If you are a radiologist you can earn money by registering with Telerays an offering your services for bidders from all over the world. If you are seeking radiology service, then you may choose from a great number of talent on TeleRays while keeping your costs low. Services are open 24/7.

Press release:

Telerays press release details (HOUSTON, October 2008):

Houston-based Radiologist Daniel Roubein, M.D., founder of Telerays says “Teleradiology was a radical step for the industry, but now serves requests on a routine basis. It provides a safe, easy way to find quality talent at fair prices. And it gives control back to the radiologists to set the fees and accept the cases they want.”

His first step was to credential radiologists nationwide and he has had great response…500 inquiries after one week. Telerays’ processes are HIPAA compliant and protect all private health information. Credentialing can take from seven to 30 days and there is no membership fee for doctors or clients. Only radiologists pre-approved by the hospital and imaging centers and fully credentialed with Telerays can bid on the contracts.

To start the bidding process, clients post their requests and all radiologists pre-qualified by them receive an email invitation to bid. The lowest bidder wins the contract, downloads the cases and uploads the final radiology reports. There are no possible delays in diagnosis because the bidding process is settled months in advance “The system has advantages for all parties,” said Dr. Roubein. “Hospitals and imaging centers benefit from market competition that gives them the best price for radiology interpretation services at any given time. By having access to a larger qualified network of radiologists, hospitals and imaging centers can negotiate a better price. There are cost-savings before the bidding even starts as we eliminate the preliminary report,” he added. Telerays provides only final reports.

For radiologists, Telerays reduces the middleman cost and gives a larger portion of the interpretation fee back to the doctor. Most services take up to 50%; Telerays takes 15% and also handles billing.

Diagnostic Imaging 2.0: Specific search engines August 2, 2008

Posted by tomography in Diagnostic Imaging 2.0, search engine, SEEKRadiology, swicki, web 2.0.

If you read John Battelle’s book titled The Search: how Google and its rivals rewrote the rules of business and transformed our culture, it is clear that without search engines the World Wide Web and the experience of its users would not be the same as it is today.

Companies such as Goto.com and Altavista.com were among the first search engines, but today Google, Yahoo and several others are the ones we turn to when looking for information on the Web. The problem with these engines is that they are not too good at accommodating the work of diagnostic imaging professionals. They cover too much virtual space, therefore their results are enormous, but most of the time they are not too relevant.

Here is a list of diagnostic imaging-specific search engines. Some are a result of small projects, while others enjoy the comfort of large support groups. They are all different, and they all work a little bit different. You have to find the one that suits your needs best.

1. As the name implies this one is a search engine fine tuned for Radiology searches, and indeed it is. RadiologySearch.net was developed by Dr. Roland Talanow, a radiology resident at the Cleveland Clinic in Ohio. His goal was to develop an engine that turns up more information from radiology-specific peer-reviewed sources while filters non peer-reviewed content. As you can see on the image you can select from 13 options before hitting the “search” button. You can search in over a 1000 peer-reviewed websites, in over 150 scientific journals, and among thousands of images, radiology cases, teaching files, books, lectures, videos. The links to all the relevant journals and societies may be found under the search area, plus all the latest news and publications appear towards the bottom of the page. Therefore this website goes beyond the traditional search page role, and resembles more to a radiology portal. Registered users may also save their individual searches for quick access, and repeated search.

Further reading:

2. Thursday, the 21st of December, 2006 was the release date of Yottalook, a radiology-specific search engine developed and actively maintained by four radiologists – Woojin Kim MD, Khan M. Siddiqui MD, William Boonn MD and Nabile Safdar MD – and powered by iVirtuoso’s algorithm. Yottalook offers four search engines: Yottalook Web, Yottalook Images, Yottalook Anatomy and Yottalook Book.

Yottalook Web has been designed to search online radiology sources only. The “Refine results” window offers a list of words every time you initiate a new search, and tries to help you narrow down your destination quicker.

Yottalook Images relies on peer-reviewed materials only, and works from a database of 700,000 images. Search results are presented in either “detailed” or “thumbnails only” mode. It supports PicLens, so that you can view all the images full screen on a 3D wall!

Yottalook Anatomy helps you find anatomical information and images with higher efficiency.

Yottalook Books is a customized and Yottalook optimized Google Book Search. It allows you to read full-text radiology books online.

According to Wikipedia Yotta is “an SI prefix in the SI (system of units) denoting 1024 or 1 000 000 000 000 000 000 000 000.” That is a lot of zeros, but a very catching name for a search engine. Could a search engine give you that many results? Find out for yourself at Yottalook.com!

3. It will not find you gold, but it will dig up just about anything besides that: ARRS GoldMiner® was created for finding images in a select group of peer-reviewed journals and now it has access to 196,130 images published in 249 radiology journals.

After initiating a search, you have the option to further narrow your results by modality, patient age and sex. What is interesting about GoldMiner® is that it “understands” medical vocabulary! For example it “knows” that gallstones and “cholelithiasis” mean the same thing by incorporating the UMLS Metathesaurus and the Medical Subject Heading (MeSH) into its technology. So, if you enter “kidney stones” it will look for images that are labeled as “renal calculi” as well, giving you an extended list of options.

GoldMiner® Global beta allows users to search Goldminer’s English-language database in their own language. It manages to do so by translating the words the user types into the search box through the National Library of Medicine. It is available in German, Italian, French, Spanish, Russian, Portuguese and some other languages.

Read the journal article on ARRS GoldMiner here.

4. “A collaborative social search engine.” That is the Wikipedia definition of a swicki. The Radiology Search Engine swicki was created by Gerard Deib and is further improved by its user community.

Swickis are easy to edit search engines, that rely heavily on group feedback. When you set up a swicki, you need to give it a name, choose a topic, and start “training” your search engine by specifying a couple websites, blogs, and wikis as starting points.

Then you need to add a couple words to the tag cloud, which is like a collection of the most popular key words. The more often a key word is used, the bigger it gets in the tag cloud, and the less frequently it is used, the smaller is gets. The editor of the swicki may add or delete words from the tag cloud at any time, whenever she feels it is necessary. Here is the current tag cloud of Radiology Search Engine:

You can see that at the time of this snapshot most people were looking for information regarding: mri breast cancer, myocardial spect images, oligodenrogliomas, and some others. The interesting aspect of the swicki search results is that each individual result may be voted on, so that they either move up or down the list:

On the above image you can see that 4 people though that the article from radiologyinfo.org was the best for “MRI neck anatomy visualized.”

When your swicki is published, anybody may be able to use it just like a standard search engine, and anybody can copy the source code to their blog or website so that your swicki will become available from their site as well, and they all can contribute to the continued growth of the swicki.

According to the company – Eurekster – behind the swicki technology, there are over 100,000 swickis already, and this number is continually growing. If you are ready, you may begin building your new swicki here.

5. And last, but not least, here is SEEKRadiology. It is still in beta at the mean time, and you may find it here:

There are all sorts of search engines that are pertinent to the field of diagnostic imaging such as Goldminer, RadiologySearch and YottaLook. But these are all on a different server with different URL’s so if you want to use all of them at once, you have to have 3 or more windows or tabs open. TomographyBlogSearch is bound to solve just that problem. It is not a search engine in itself, but it is a clever use of some old HTML and new Java Script to ease your search needs.

It is very simple to use: just type your key words in the search box, and then click on the name of the search engine you wish to use. There is no need to type in your key words again if you wish to switch between the search engines. Your results will open in new windows, so that you can go back to your original search whenever you need.

SEEKRadiology is being developed by Péter, Herczeg and András Székely. Here is a sneak peak at SeekRadiology V1.0 coming very soon:

I hope you have enjoyed the first edition of Diagnostic Imaging 2.0. We are going to take a closer look at social communities for diagnostic imaging professionals next.

A {better} way to read Wikipedia August 1, 2008

Since its launch on the 15th of January 2001, Wikipedia has been by far the best example for Web 2.0 at work. With over 10 million articles in 253 languages, it is the largest, free, volunteer written encyclopedia in the world. Even though it is a great collection of information, it does not quite have a decent search engine, so sometimes it just a little bit too difficult to find the answers to our questions. The answers are there, but finding them has been difficult. Up to now, that is.

Meet PowerSet; a clever search engine designed especially for making your Wikipedia experience more pleasant. With PowerSearch you may find the exact, short answers to your questions such as: “Who invented the periodic table?” or “What is PET/CT?” and so on. Here is this latter example:

This is exact, isn’t it? And if you open the whole article and click on “Explore Factz” on the top left hand corner, you will get a word cloud similar to a blog’s word cloud with which you can get another step closer to finding your answer. If you click on a word in the word cloud, it will be highlighed in the “Article Outline” where words appear within their own context giving you a better idea where your answer lies. The “Article Outline” follows you as you scroll on the page.

Watch the demo video on PowerSet here, and make your next step towards Web 3.0!

The Ultimate Medical Wiki July 29, 2008

Harvard Medical School, Stanford School of Medicine, University of Michigan Medical School, and Berkeley School of Public Health have put their heads together and launched what we might eventually call the ultimate medical wiki called Medpedia.

The Medpedia community seeks to create the most comprehensive and collaborative medical resource in the world. Medpedia will serve as a catalog, database, and learning tool about health, medicine and the body for doctors, scientists, policymakers, students and citizens that will improve medical literacy worldwide.

Associations, medical schools, hospitals, government organizations and research centers are asked to join to this worldwide project and help build the world’s largest and most relevant medical information database. In order to keep the contents accurate and up-to-date, contributors will have to have an M.D. or Ph.D in a biomedical field, and all contributors will have their own profile page with links to their contributions. This will help minimize errors and prevent pseudoscience. The project is in beta at the moment, so it is by invitation only, but if you are eager to contribute, you may ask for a login at the Medpedia website.

Unfortunately, I still have another year to sit out at school until I can contribute, but if you are a diagnostic imaging professional you should sign-up because this is a worthwhile project!
