SPeCIAl SeCTIOn HeAlTH IT Image Management: The Online Option into the PACS environment was not available when the practice installed digital mammography, says Director of Information Systems David Grandchamp. The practice decided to use InSite One for an offsite, online digital mammography archive. “The InSiteOne retrieval model differs from the conventional PACS model,” explains Grandchamp. “[Rapid] retrieval is always guaranteed.” Most PACS, on the other hand, guarantee retrieval for a few weeks to a few months, and then response time drops off. In addition, the conventional PACS model does not fit mammography as well as an online image management system. That’s because radiologists nearly always require prior digital mammograms, so efficient workflow hinges on rapid retrieval of archived images. What’s more, digital mammograms are hefty files that can consume an inordinate amount of space in a conventional PACS. A final advantage of the online approach, says Grandchamp, is that the archive remains an operating expense. The InSite One archive has grown with the radiology practice. Initially, the practice installed three distinct databases at each office offering digital mammography. A T1 line linked the office. The model worked—except when a patient used a different office for the follow up study. In those cases, the digital practice generated films. In 2006, Robert D. Russo and Associates invested in a network upgrade, installing a 1 gigabit fiber optic bandwidth line between its offices. Internally, the practice consolidated its databases into a large proxy server. Now radiologists can access mammograms regardless of the acquisition site. In addition, the practice uses DeJarnette Research Systems PACSware Intelligent Router for pre-fetching. The results are impressive. “Prior mammograms are available immediately, rather than a few minutes,” says Grandchamp. With razor-thin mammo margins, seconds saved represents financial returns. Grandchamp decided to remain with the successful online archive approach even after the practice deployed PACS. “Mammography is a different beast than other modalities.” The large files can take a disproportionate bite out of the storage budget, and the constant need to retrieve prior studies is unique. InSite One also maintains backup archives in Arizona and at its Wallingford, Conn., headquarters. Get the complete picture.
