May 15, 2008 - McKesson acquired Vivalog, a provider of Web-based solutions, taking control of the MyPACS.net medical imaging reference site that enables radiologists, cardiologists and other imaging specialists to organize and share image and reference case information needed during daily practice.
By providing imaging specialists with instant access to related cases, the Vivalog system reportedly saves time by eliminating unnecessary steps. A fully integrated reference case management solution is designed to provide staff with faster access to their peers' knowledge and an efficient way to capture and share their own evolving knowledge.
Vivalog also facilitates collaboration and communication among radiologists during the diagnostic decision process.
MyPACS.net reportedly houses the largest collection of online teaching files, serving as a global, comprehensive decision-support resource. Since its inception eight years ago, users have contributed 18,000 reference cases depicting thousands of diseases. Cases are displayed using patent-pending Web technology that lets the users manipulate images directly in their browser without need for additional software. Each month, the site receives approximately 1 million page views from 70,000 imaging professionals around the world. Vivalog's most recent innovation uses biomedical case management and collaborative knowledge-sharing technologies to support image-based research and clinical trials.
