Medical Imaging Study Flags Portable Media Problems
Radiologists and referring clinicians frequently use CDs and DVDs to review patient medical images (e.g., MRIs and CT scans) acquired at outside imaging centers, but issues regarding access, importability, and viewing of these portable media could negatively affect patient care, according to a study published in the January issue of the Journal of the American College of Radiology.
The report looks at current practices for portable media use for medical imaging in both academic and nonacademic radiology departments in the United States.
Researchers from Johns Hopkins University in Baltimore reviewed a 22-question survey of members of the Association of Administrators in Academic Radiology, the Association for Medical Imaging Management, and the University HealthSystem Consortium.
The 102 responses revealed three problem areas regarding portable media: access, importability, and viewing issues. Other major issues included noncompliance with the Digital Imaging and Communications in Medicine (DICOM) standard and/or corresponding Integrating the Healthcare Enterprise (IHE) profile, and a lack of knowledge about compliance.
Ninety-eight percent of respondents said that their institutions produced DICOM-compliant media; 2.0% were uncertain. However, only 22.2% of respondents claimed their institutions produced IHE Portable Data for Imaging (PDI)-compliant media, while 71.6% were uncertain.
Only 16% of respondents' institutions routinely tested for DICOM and IHE PDI compliance. "We were quite surprised to learn that only a few facilities routinely tested their media," says Katarzyna J. Macura, MD, PhD, Department of Radiology and Radiological Science at Johns Hopkins, an author of the study.
The survey didn't explore the "why" behind the low numbers, says Macura. Questions in the survey were designed to establish the status of existing policies on portable media, she explains. They did not ask about the rationale to implement or not implement those policies. "We aimed to learn whether they had any [such policies] and how they were handling portable media."
"We hope to raise awareness of the problem and promote routine media testing, for which several tools do exist," she said.
