E. CNDA Site OverviewThe CNDA website enables users to review, retrieve, and upload image and non-image studydata. Data within the CNDA are organized within separate projects. In order to interact withthe data for a particular project, you must be granted explicit access to that project by theproject owner.You can review which projects you have access to by clicking the “My Projects” link. Youshould see two projects for your participation in the INTRuST study, one for quality controlacquisitions (qualification volunteers and phantoms) and one for the actual study data. If youdo not see these projects, please contact: cnda-help@npg.wustl.eduThe “My Projects” pages should include two projects for your INTRuST study site, one forresearch participants and one for quality control data.F. Uploading Research Participant ImagesTo upload the DICOM images from a participant imaging session, click on the ‘launch uploader’button on the top left-hand side of the CNDA homepage. If you receive a warning, asking youto give this tool permission, approve the request. The tool will walk you through the uploadprocedure. If this is the first time you are uploading a scan for a subject, you need to create anew subject (see section 6.3 or 7.4 as appropriate for subject and session naming). If you donot see the appropriate projects and study participants listed in the upload tool menus, contactcnda-help@npg.wustl.edu .Note to Mac users: If you intend to upload files from a CD or DVD, the directory for theCD/DVD drives is tricky to find. From the pop-up menu at the top of the "Open" window,select the startup disk (usually the last item in the menu). Then, in the file browser, doubleclickthe "Volumes" folder to open it. This folder contains entries for all disks mounted onyour computer, including CD/DVD.Note about de-identification: Prior to transferring the files to the central database, the uploadtool removes all information from the image files that could identify your subject Once theupload is complete, you must proceed to the CNDA website to verify the upload andenter study notes. When the uploadcompletes, click on the “View uploadedsession” link. A page detailing the study in theCNDA will be displayed. Click on the Edit linkin the Actions box on the right-hand side ofthe page.On the subsequent page, verify that all of theseries are present, that the correct number offiles has been uploaded, and that the totalupload size is correct for each series. Ifthere are any discrepancies, contact:cnda-help@npg.wustl.eduFor each series, enter any notes that havebeen written on the study worksheet for thatseries in the note section provided. If a serieswas indicated to be unusable (e.g. it was notcompleted), select “unusable” from the Qualitymenu. If a series was indicated to have potential problems, select “questionable” from themenu.
Finally, in the “Additional Notes” section, enter any notesthat have been written on the study worksheet that areapplicable for the entire imaging session. When finished,click the “Submit” button.G. Demographics FormAfter each scan, the study coordinator is required to fillout the subject demographics form on the CNDA system.In the project screen, click on the subject name that wasgiven in the upload applet (see section 7.4 for namingconvention). From the Study Details screen, click theEdit link in the toolbar on the right side of the screen. Fillout the “Edit subject archive” form using the informationobtained from the demographics questionnaire andneuropsychological testing. If the subject is not a TBIpatient, leave the DateOfInjury field blank.H. Radiologist’s ReportEach subjects’ MRI is required to be read by a clinicalradiologist. To enter the results of the clinicalradiologist’s report:• Open the subject in CNDA• Open the MR Session• Scroll to the bottom of the pageand click “Add Rad Read”• Fill out the form with theradiologist’s name and “Brainwithout Contrast” as the examtypeI. Uploading Quality Control ImagesIf this is the first time you are scanninga particular human volunteer orphantom, you will need to create anew subject on the CNDA. To do this,complete the New Subject Form. If thissubject or phantom has been scannedbefore, DO NOT complete a NewSubject Form.After logging in, click on the “New” item in the top menu and then click on “Subject”. Selectthe QC project for your site. Enter the subject’s ID. For human volunteers, the Subject IDshould be of the form INTRuST_023_###, where ### is an incrementing number for eachvolunteer imaged at your site (e.g., INTRuST_023_V_001). For phantoms, the Subject IDshould be of the form INTRuST_023_P (e.g., INTRuST_023_P). You should always beusing the same phantom so the Subject ID never changes. The rest of the phantom-subjectform can be left blank. Click the Submit button.You can now proceed with the upload. When uploading quality control scans, make sure toselect your site’s QC project, and to use the correct Subject ID. See section F above fordetails on the upload process. For additional information on INTRuST naming conventions,please see sections 4.4 and 6.3 of the INTRuST Technical Procedures Manual.
