Purpose/Background: Asynchronous transfer mode (ATM) network technology has recently been used for high speed transmission of radiological images between hospitals and inside hospitals. However, the number of clinical sites which routinely use this technology is limited. The purpose of this study was to analyze the very early impact of an ATM link between a large tertiary referral center and small peripheral clinic on cost and clinical practice. Methodology: An ATM link using 155 bps (OC3) technology was installed between the West Los Angeles VA Medical Center and the Sepulveda VA, a large outpatient facility which provides full service radiological services. The West Los Angeles VA Medical Center is a large tertiary referral center with sub-specialist radiologist. The clinical impact of this ATM link between a large full-scale DICOM-3 compliant PACS system at the West LA VA on a smaller PACS system at the Sepulveda VA was evaluated. Results: The ability to freely exchange complicated MRI and CT studies between a tertiary referral center and a clinic could have a direct impact on patient care. Over the last six months, all and CT studies from Sepulveda VA were readily available via the ATM connection to all radiologists at the West LA VA. On average the workload at the Sepulveda VA in CT and MRI was about one tenth of the same workload at West LA VA, thus creating interesting possibilities for sharing or radiologist resources. Conclusions: Although our preliminary data and work loads have been too limited to draw any final conclusions yet, we feel that future results will show that the ability to provide immediate and fast interactive consultation between general radiologists in a large outpatient facility and sub- specialists at a tertiary referral center can have an impact upon the quality of patient care.
