RSNA 2012 - ISP: Informatics (Education and Research)

A diverse group of different presentations in this session about informatics aspects in education and research. I've included a short note on the presentations I found most interesting.

MIRC in the Cloud
Houman Ebrahimi MBBS * , New Lambton Heights, NSW, AUSTRALIA • Arash Jalalian PhD *

Presentation on how to use MIRC, the free RSNA teaching file system. MIRC viewer app can be used on the iphone and ipad to review cases inside the MIRC system. The app can access the public servers and allows entry of a private server, if available, using login credentials. Images are shown full screen both on iphone and ipad. Cases can be saved on the local device for later review. The locally stored collection is shared through the icloud and thus available on all devices connected.

Decision Support for Radiological Interpretation Using Online Knowledge
Mina Ghaly BA , Palo Alto, CA • Daniel L. Rubin MD *

Challenges for radiology are the increase in imaging, the variation in the interpretation of imaging studies, and the lack of immediate access of knowledge sources.
Semantic wiki is used to setup the data collection for the decision support system. Using this, the authors made a lilver pathology system. The semantic wiki system is used to provide a support by providing a differntial diagnosis with a confidence percentage per specific diagnosis. Percentage correct diagnosis in a test with 8 residents increased as did the confidence in their final diagnosis. The system also allowed faster reading time.

Making PowerPoint Work for the Radiologist: Visual-enhancement Techniques to Improve Education
Jonathan Edward Scalera MD , Boston, MA • Stephan W. Anderson MD

Powerpoint fails to provide image stacking, magnification, and real-time contrast and brightness adjustment. The authors have developed a portable solution using VBA within powerpoint.
They provide advanced capabilities within a powerpoint
- a real time pop-up zoom window
- brightness and contrast setting in both the main window and zoom window
- In presentation mode you have real time editing possibilities such as move around, crop and zoom
- image stacks with jump to first and last and the abity to go through the stack at different speeds

It is a great tool and can be obtained from

De-identification of DICOM Image to Meet Good Clinical Practice Guidelines and European Union Data Protection Regulations
K. Y. E. Aryanto , Groningen, Groningen, NETHERLANDS • Matthijs Oudkerk • Bert Moorlag • Peter M.A. van Ooijen

The use of medical data in research projects is subjected to diffferent guidelines and regulations that dictate how the patient privacy should be protected. A set of DICOM header elements is suggested to obtain optimal de-identification of medical data.
This work was highlighted on auntminnie.
