The Online Radiology Elective

The Online Radiology Elective AKA RWJMS StudentPACS 2 wk ElectiveSalil Soman, MD, MSRadiology Resident, UMDNJ RWJMSSpring 20091WelcomeWelcome to the Robert Wood Johnson Medical School Department of Radiology Interactive Radiology Elective Student PACS.We look forward to having you rotate with us!2See One, Do One, Teach OneOn this rotation students are introduced to a selection of disease entities represented in imaging studies.They then independently re-review the cases at PACS workstations and select images that best visualize the disease for presentation in SPACS modules.They also research the disease process and create a series of questions which convey pertinent facts about the presentation, diagnosis, and management of that entity.Their final modules are then added to the Student PACS web site as tutorial modules.3Finding A Needle In a Hay StackAside from the act of recognizing a identifying a finding on a single image, radiologists often have to search through a series of images (from tens to thousands per study) to find the pertinent findingsThese modules seek to simulate this process of searching not only on a single 2D image, but through a series of them.4First StepsGet registered for the elective through registrarComplete Our Online form prior to first day of rotation (As early as possible after officially being registered for the rotation)Make an appointment to meet with a supervising resident on the first day of rotationIf you own them, bring your laptop and USB drive to the first day meeting (not required)5ExpectationsSelf Directed WorkGoal Oriented Reference SearchesDelivery of Final Products by decided guidelinesUsually completion of 6 to 7 modules by end of rotationUsually submission of first draft of all modules by Monday of second week.6About The Web Sitehttp://rwjradiology.umdnj.edu under Educational Material sectionStudentPacs subsection:http://www2.umdnj.edu/radpweb/SPACS2/index.htmlSite HighlightsAbout the projectCurrent StaffInstruction manualsExample modulesModules of previous rotation studentsRotation registration form.7About SPACS Flash ModulesCreated by RWJMS Alumni and Radiology Dept Faculty & ResidentsThe SPACS module is a Macromedia Flash animation that presents serial images, like those from a CT or MRI study, in a simulated PACS interface. It allows medical students and residents to experience the human body like they would at the expensive PACS workstations from any computer. Users can flip through images, zoom in, and pan around to follow structures through slices of images at their own pace. Pre-defined areas of interest, which we call "findings, can be selected by the user, prompting the program to ask a set of questions. Because the modules are created in Flash, they are inherently easy to distribute, either over the web or other means. File sizes relatively small and the compatibility is nearly universal.

17Your File StructureCreate a folder titled with your nameWithin that folder create subfolder for each of your modules titled with the module name, containing:A folder with all of the source jpeg images you usedwhen creating a new module, tell software to save it into the folder created for that module, which will make .fla fileWhen you publish your project, it should create .html and .swf files in the modules folderA word document with all of the text you entered into the software for each finding, answer, etc use for spell checking and later for indexing the modules for searchThe text file with your html for the module (see later slide)A word document which lists what image numbers your findings are on, and which contains your title, description and radlex keywords.18Overview Creating CasesFlash 8 ProfessionalStudent PACS extensionUsing the Student PACS extension19Using the Extension in Flash ICreate a new module with extension panelName and save the file as described on the Your File Structure slide.Direct the subsequent dialogue box to the location of your jpeg imagesCreate hot spots on your imagesFor each hotspot create findings and questionsMAKE SURE THE In Order option IS SELECTED20Using the Extension in Flash IIAt the end of EVERY explanation should be a referenceAt the end of the last question for each finding, add text as a new paragraph after the reference for the explanation of the last question giving the user a CLUE that they go look for another finding (for all explanations except the LAST finding).Choose the close or save option from the SPACS panel once you are done working on the module.When you are ready to view the module in a web browser choose Publish from the SPACS menu on the SPACS panel within flash.

21If You Cant Find the SPACS PanelOpen Flash ProfessionalCreate a new blank documentThen look under the Windows drop down menu, choose the Other Panels option and StudentPACS should be an option under the subsequent menu.22VersioningWhen you create a module, all of your work gets save as a .fla file.We recommend keeping a copy of the last working version of each .fla file when making changes (so you can go back to the older file that worked in case something goes wrong with your changes)This should be done manually from the computer using the copy command (not using Save As from within flash)23About ReferencesEVERY answer in the module, regardless how fundamental needs to have a reference (textbook, journal article, web site less preferable) including at least a chapter number, though page number is preferred.All references should be in standard MLA format.If you find it helpful, UMDNJ provides a free copy of EndNote to all UMDNJ students (http://www.umdnj.edu/librweb)

25The Development ProcessOnce you have created your first draft of your first module, select the Publish option from the SPACS menu on the SPACS panel. This will result in a .html and a .swf file being created in your folder for your module.Email your supervising resident the .html and .swf files for your first module along with a list of on what image number in your .swf each finding is on.This will require you to look at the html file in a web browser to get the image numbers.You may need a send file service like yousendit.com to send the swf and html files. (yousendit allows you to send files up to 100 MB for free).26Radlex ClassificationOntology created by RSNA for classifying radiological entities, similar to the SNOMed and MESH ontologies which are used in indices like PubMedRadlex Term browser at http://radlex.orgTerms help make modules discoverable via searchesEach module should have radlex terms identified.
