  1. ACRIN Imaging Core Laboratory 1

  2. Aim 1: To ensure uniformity and high quality of test performance, image acquisition and image interpretation throughout the trial • Aim 2:To develop/deploy technical systems for test transmission and archiving, including creation of a unique data resource for ancillary studies by combining diagnostic tests and clinical data 2

  3. TRIAD Installation & Sample Data Transfer 3

  4. TRIAD • TRIAD is the American College of Radiology Imaging Network’s (ACRIN) image acquisition and management software. In brief, TRIAD-OA offers a web-based software solution which allows sites participating in the RESCUE trial a secure method to review and submit clinical trial images. For a more detailed explanation of the capabilities and benefits of TRIAD, you may visit the TRIAD learning center at: https://triad.acr.org/

  5. TRIAD REGISTRATIONandDEPLOYMENT

  6. TRIAD DEPLOYMENT • Identify the following key individuals at your site: • TRIAD user – the individual(s) who will use TRIAD regularly • IT contact – the individual(s) who will assist with the basic installation and testing of the TRIAD software • PACS administrator (if necessary) – the individual(s) who will assist with transporting case images from the scanner/PACS system to TRIAD • Register for a TRIAD account – this may be done by clicking on the following link: https://triad.acr.org/Web/UserAccount/Register.aspx • Determine the computer(s) which you would like TRIAD installed on (this machine does not need to be used solely for TRIAD) • Determine a time and date that would work best to schedule the TRIAD installation

  7. Prior to a TRIAD installation please register for a username & password @ • https://triad.acr.org/Web/UserAccount/Register.aspx

  8. TRIAD INSTALLATION • If you feel your site is ready to proceed with the TRIAD installation, please submit an e-mail to TRIAD-Support@phila.acr.org. Include the following information with your e-mail: 1) date and time you would like the installation to take place, 2) individuals who plan to participate in the installation, 3) site name and number and 4) contact information.

  9. Selecting TRIAD Options • TRIAD: TRansfer of Image and Archive Data • TRIAD setup is customizable with two (2) basic options for submission of images originating from, or routed through, the Clinical Site 9

  10. TRIAD Client • Installation of TRIAD client application only • For submission of images directly from CD or folders • Recommended for low volume sites -Fewer than five (5) CCTA submissions/month

  11. TRIAD Site Server • Installation of TRIAD client application and TRIAD site server • For submission of images transferred directly from a site’s PACS or Scanner on the same local area network • Recommended for high volume sites - five (5) or more CTA submissions/month

  12. TRIAD Client Hardware and Network Requirements: • Model: PC • Processor: Intel P-IV 3 GHz minimum, Intel Core 2 Duo 2GHz is recommended • RAM: 1GB is minimum, 4GB is recommended • HDD: 200Mb for Rich GUI client application itself up to 200Gb- for local image cache, its size will depend on amount of images stored by the system • Video: Graphic adapter and Monitor with True Color mode support 1024 x 768 pixels x 32 bit color mode • Supported Operating systems and Software Requirements: Workstation running Rich GUI client must be: MS Windows XP SP3, MS Windows 7, MS.NET Framework 3.5 • Network Requirements: Internet connection- minimum Client connection speed should be at least 256 kbps. Desired connection speed is 1 Mbps. 12

  13. TRIAD Site Server Supported Operating Systems and Software Requirements: • Windows XP SP3, Windows 7 and Windows Server 2003 SP2 • Microsoft .NET Framework 3.5 ,SQL Express 2005 HARDWARE REQUIREMENTS • Model: PC • Processor: Intel P-IV 3GHz minimum, Intel Core 2 Duo 2GHz is recommended • RAM: 1GB minimum, 4GB is recommended • HDD: Its size depends on amount of images received from Scanner before they are sent to TRIAD Image Storage.100 Gb minimum, 200Gb is recommended.

  14. TRIAD Letter & Consultation Call

  15. TRIAD Greeting Letter is sent (via e-mail) to Site Study Coordinator • Prepares your organization by providing requirements for an installation • ACRIN holds site consultation call with each site • Site Study Coordinator should be prepared to confirm the following information: • Installation plan/process for image transfer • Number of TRIAD installs required • TRIAD Installation occurs on scheduled date/time • Site will be required to submit a test exam during installation to confirm successful TRIAD deployment 15

  16. Preparing QA Datasets

  17. One (1) CCTA and One (1) SPECT MPI should be submitted to ACRIN core lab for qualification • For sites with inadequate studies, the ACRIN core lab will review the protocol recommendations with the site, and request an additional study until the site fulfills all requirements • Once a modality’s requirements are met, an ACRIN Imaging Technologist will send a modality specific approval letter via email to the site Study Coordinator • Once all imaging modalities are approved, the RESCUE PM will send an official letter of acceptance for accrual via email to the site Study Coordinator

  18. CCTA Quality Control Procedures

  19. Image Transmittal Worksheet (ITW) must be fully completed & submitted for every CCTA exam • Datasets should be consistent with Diagnostic Testing Protocol Recommendations • ACRIN Image Technologists will complete Quality Control (QC) form, review data for completeness of dataset, and quality of images 19

  20. CCTA Image Transmittal Worksheet (ITW) Form The ITW Form contains study-specific information (i.e., Subject ID, Scan Date, Image Details Once images have been uploaded to TRIAD, the ITW should be faxed to ACRIN This form indicates that the images are on TRIAD and ready for evaluation by ACRIN

  21. CCTA Quality Assessment: • Absence of major motion artifacts • Sufficient contrast enhancement • <15 mSv radiation dose 21

  22. CCTA Completeness: • ITW • Scout • Dose Report • Prospective gated non-contrast Calcium Score series (optional) • Prospectively or retrospectively gated contrast enhanced scan • If global and regional LV function is assessed, use of multiphase axial reconstructions (1.5mm) throughout cardiac cycle are required • If routinely performed at your site, a full field of view chest scan for incidental findings

  23. CCTA Core Lab, the Cardiovascular Imaging Core Lab (CVIC) at Massachusetts General Hospital CCTA Core Lab at MGH will assist ACRIN in the development of general and specific protocol recommendations. The CCTA images from the first two study subjects at each site will be reviewed by the Core Lab at MGH as well as a random sample of 10% of all cases thereafter. CCTA questions related to image acquisition or interpretation e-mail: rescuehelp@partners.org Erin Corsini, Clinical Research Associate, Cardiovascular Imaging Core Lab, MGH

  24. SPECT MPI Quality Control Procedures
