Development of a free knowledge base to support the use of differential diagnosis information in PET-CT imaging. June 3, 2010

Posted by tomography in Conference, Nuclear Medicine, Radiology, SNM 2010.

Here is the second project I am involved with that will be presented at SNM 2010 in Utah.

Development of a free knowledge base to support the use of
differential diagnosis information in PET-CT imaging.

Zoltán Tóth, Zoltán Barta, András Székely, Nikoletta Pócsi, Ildikó Garai.


Our aim was to create an application integrated into the reporting
workflow to provide quick and easy access to relevant scientific
publications, facilitate the use of differential diagnosis information
and support evidence-based decision making. This project is part of a
larger project targeting the development of a structured reporting
system (ReportAssistant) for oncological whole-body PET-CT studies.
(See accompanying poster).


Creation of a PET-CT gamut list

The gamut list was created by combining the results of two independent
methods. First we selected 160 representative reports from our
practice. These were processed sentence-by-sentence by two physicians
in order to extract the most common and less frequent findings in
whole-body PET-CT studies. Copies of the original report text were
modified inline: sentences describing relevant lesion types were
“tagged” with “location – lesion – diagnosis” triples. These tags were
collected and summarised as potential gamut items with the help of a
software script. Parallel with these, a second list was created by
processing and sytntetising various scientific literature sources.
After reviewing, these two lists were merged to form the first edition
of a PET-CT gamut list. These version of the list covers chest,
abdomen and pelvis related lesions and consists of 400 gamut items.

Collecting and tagging publications

Systematic literature searches using a comprehensive list of keyword
expressions distilled from the PET-CT gamut list were conducted. The
main target journals were Radiology, Radiographics (both official
journals of RSNA), Journal of Nuclear Medicine (the official journal
of SNM) and European Journal of Nuclear Medicine & Molecular imaging
(the official journal of EANM). A total of 745 articles were selected.
The URL addresses of the full text articles were recorded and manually
tagged with proper gamut triples. Further processing, including
downloading and indexing of PDF articles, was automatically done by
custom software written by one of the authors (Z Barta).

Software development

All software development was done by using the X4Tk toolkit. X4Tk is
an open source (LGPL), object-oriented MVC-framework for easy desktop
application development and more, including support for standard
enterprise messaging protocols, TCP/IP based server-client development
and various interprocess communication solutions. X4Tk is written in
Perl by one of the authors (Z Barta), with the first release in 2005,
it is actively maintained and field-tested.


Database of tagged publications

A comprehensive collection of high-quality, manually selected,
properly reviewed and tagged radiology and nuclear medicine
publications was generated by using the methods described earlier with
the help of our custom RA PaperManager software. This list can be
exported to an external file. By loading this list one can easily
rebuild the database on his own computer without violating copyright

RA PaperManager software

The main features of RA PaperManager are:

* extensive support for collecting scientific papers ranging
from dragging-and-dropping of files to direct web browser integration through
bookmarklets, respectively import of list of URLs pointing to full
text PDFs and scanning & monitoring of hard drive directories.

* “free” and gamut-list based tagging of papers

* full text search support

* easy linking & interprocess communication with other
applications (STOMP, Windows MMF, HTTP)


We have designed, implemented and tested a highly useable, general
purpose, point-n-click SR software. Our software system can serve for managing personal collections of scientific publications and it can be easily integrated into structured reporting softwares through it’s REST API. The
software is available under various licenses, including free licenses
for personal and academic institutional usage.

Look for Zoltán Barta and Zoltán Tóth on site for more details!

Practice anatomy skills online May 23, 2009

e-anatomy: interactive atlas of human anatomyAs a medical student, I never had a decent seminar in Radiology. Week after week we would go into a tiny room, and our doctor would show us x-ray and CT images from a distance of up to 10 meters (why didn’t I get closer? – because the room was crowded!) So how on earth was anybody supposed to learn in that kind of invironment? I am not proud of it, but I did not get much out those afternoon sessions. Even so, during my clinical rotations, I was expected to recognize certain lesions on CT, but I was not too successful as you may imagine.

That is why I am so glad I fould e-anatomy! Absolutely free of charge I get to practice my anatomy skills through CT and MRI images on a virtual workstation. The image quality is excellent, the labels are very informative, and if I chose to upgrade for only 40 dollars a year I could get even better service. Other subscription options are 1 dollar for a day, or 9 dollars for a month.  Institutions can also purchase a larger package, but the price is not available on the website.

All you need is a browser that supports Adobe Flash (sorry iPhone users), and a quick, free registration. They have a wide range of available content:



Skull, Sinuses

Temporal bone


Face (Bones)

Face (Soft tissues)




Arm, Forearm, wrist and hand

Hip, Thigh, Leg

Lower limb (arteries and bones)


Ankle and foot

Give it a try, and let me know how you liked it!

Radiation and cancer May 21, 2009

Posted by tomography in Cancer, Nuclear Medicine, Radiology.
1 comment so far


Diagnostic scans, whether it is a plain x-ray or CT scan, use some form of radiation and for those who are exposed to radiation sources, the doses eventually add up over the years and may disrupt cell division.

While debated, a recent study suggests that radiation exposure from medical imaging may be responsible for 1-3% of cancers worldwide. In 2004, Lee et al. concluded that “patients are not given information about the risks, benefits and radiation dose for a CT scan”. Additionally, this study found that both patients and physicians were “unable to provide accurate estimates of CT doses”.

If you are curious about your risk data, head over to Xrayrisk and calculate your own values. Just type in your age, the type and number of scans you have had so far, and the approximate dose value in mSv!

The frequently asked questions section of this website contains some short, but detailed descriptions of the various modalities, including Nuclear Medicine modalities, that may be valuable for patients.

Don’t forget, though, it is all about probability! Not one test will ever be able to predict for sure whether someone will have any form of cancer in their lifetime.

Right Scan Right Time

I have come across a valuable website that is something the imaging community has been missing for some time. RightScanRightTime is a platform that encourages patients and physicians to share imaging stories, but it contains resources that may be useful for both patients and doctors:

Scan 101: This section explains briefly, but clearly what modalities are used today in Radiology and Nuclear Medicine, so it is great for patient education.

Research: The site contains an easily-searchable data base of peer-reviewed research demonstrating the patient and economic value derived from medical imaging.

Stories of imaging: Here you, as a patient or as a doctor, can share your imaging story or read about someone else’s experience. I am sure this will help alleviate a lot of people’s fear of imaging modalities.

I highly recommed the site, though the Scan 101 section could be a little bit more detailed.

Diagnostic imaging community sites list update May 15, 2009

Posted by tomography in Community sites, Diagnostic Imaging 2.0, Nuclear Medicine, Radiology.

I have recently updated my list of community sites, and here are the changes to the original post:

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.
