One aspect of the Georgetown image management and communications system (IMACS or PACS) is a built-in capability to support teleradiology. Unlike many dedicated teleradiology systems, the support of this capability as a part of PACS means that any acquired images are remotely accessible, not just those specifically input for transmission. Over the past one and one-half years, two radiologists (SCH, BSG) in the abdominal imaging division of the department of radiology have been accumulating experience with teleradiology for on-call support of emergency abdominal imaging, chiefly in ultrasound. As of the time of this writing, use of the system during on-call (one of these attending radiologists primarily responsible) or back-up call (the attending responsible for the Fellow on primary call) has resulted in a marked reduction in the number of times one of them has to drive to the hospital at night or over the weekend. Approximately 80% of the time, use of the teleradiology system obviates having to go in to review a case. The remainder of the time, the radiologist has to perform a procedure (e.g., abscess drainage) or a scan (e.g., complex Doppler study) himself. This paper reviews the system used for teleradiology, how it is electronically and operationally integrated with the PACS, the clinical benefits and disadvantages of this use, and radiologist and referring physician acceptance.
