A recent advisory by the FDA urging breast imaging facilities to ensure compatibility between full-field digital mammography systems and PACS exposed an ongoing problem: Interoperability issues persist as some vendors fail to comply with healthcare digital imaging standards.
A recent advisory by the FDA urging breast imaging facilities to ensure compatibility between full-field digital mammography systems and PACS exposed an ongoing problem: Interoperability issues persist as some vendors fail to comply with healthcare digital imaging standards.
The FDA learned that image quality from a number of FFDM units was being compromised when displayed on some third-party PACS. According to the agency:
These issues could lead radiologists to overlook or misplace suspicious lesions, a problem that escalates when images end up at facilities unfamiliar with the configuration of equipment originally used to perform the mammogram. The FDA thus recommended July 29 that all facilities check to ensure that image-identifying information is correctly displayed on both soft- and hard-copy FFDM images.
This issue highlights why it is critical for purchasers of digital mammography, mammography computer-aided detection, and PACS and workstation equipment to contractually bind their vendors to strict support of all relevant portions of the DICOM standard as well as the technical frameworks of the Integrating the Healthcare Enterprise initiative, specifically the Mammography Image Integration Profile, said Dr. David S. Channin, chief of imaging informatics at Northwestern University's Feinberg School of Medicine in Chicago."These standardization efforts are specifically focused on reducing these kinds of interoperability issues across systems and vendors," Channin told

Imaging.Each year, the IHE holds connectathons in Asia, Europe, and North America. The connectathon is a large-scale healthcare IT industry interoperability testing event where vendors of multiple systems and platforms check their connectivity, exchange information, and perform thousands of digital transactions. The IHE recently published the results from the IHE-Europe and IHE-North America connectathons. Of 32 PACS vendors, only 13 fulfilled IHE's image display

.The IHE Radiology Mammography subcommittee is always developing new technical frameworks that affect digital mammography. Therefore, customers must insist that their vendors participate in the IHE process and deliver support for the new IHE frameworks within a short time after their finalization, Channin said While participation in IHE and compliance with these frameworks cannot guarantee that issues like those identified by the FDA will not arise, they reduce the likelihood of such occurrences, he said."The FDA, for its part, should consider mandating such compliance as a way of accelerating market driven forces for adoption," Channin said.For more information from the Diagnostic Imaging archives:
