June 9, 2009 - Using McKesson’s Horizon Study Share reference case solution, the American College of Radiology (ACR) has made its entire library of ACR Learning File images and content available online as a Web-hosted archive to ACR members and others in the field. The ACR Learning File includes a collection of more than 3,600 peer-reviewed cases in 12 subspecialties, with more than 10,000 high-quality images depicting thousands of diagnoses. Key findings and detailed discussions supplement the images, making the library a unique experience for practicing radiologists and members in training. McKesson worked with ACR to transfer the entire ACR Learning File library from CDs into the Horizon Study Share repository.
“Given the dynamic nature of radiology and the need for anytime/anywhere access to current information, offering the ACR Learning File library online helps us to ensure this essential resource is readily available, relevant and reliable,” said Lawrence Davis, M.D., FACR, chair of the American College of Radiology Education Commission. “We are extremely pleased and excited that physicians can now have immediate access to these materials in any browser, on any platform, anywhere in the world.”
ACR Learning File Online subscribers can view cases through the Horizon Study Share case viewer, which provides a PACS-like experience in the browser. Images are automatically resized to fit the viewing window, and users may zoom in and pan around on images in real time. In addition, Horizon Study Share, which also powers the well-known MyPACS.net medical imaging reference Web site, offers a streamlined interface for ACR contributors and editors, revolutionizing the content publishing process. As an additional value-add, the search function for the ACR Learning File Online will return results from the ACR archives and notify the physician if additional case studies on the topic are available on MyPACS.net.
“The ACR Learning File is a collaborative effort involving thousands of members who now benefit from the ability to easily create, review, edit, and share cases online,” said Joe Biegel, vice president of product management, Horizon Medical Imaging, McKesson. “Horizon Study Share is designed for organizations seeking a plug-and-play teaching file solution with the most innovative features available. McKesson is proud to support ACR as it expands the reach and value of such a vital resource.”
Horizon Study Share combines intuitive authoring tools and a flexible viewer with powerful case management functionality. It is HIPAA-compliant and supports MIRC, DICOM, SQL and XML connectivity.
