title: Teleradiology for remote diagnosis: a prospective multi-year evaluation.
abstract: Teleradiology has been used for nearly 3 years at our institution to provide urgent radiologic interpretations for two outpatient clinics and an affiliated hospital. The purpose of this study was to evaluate the clinical reliability of the existing system. Teleradiology images were interpreted using 1600 x 1200 pixel display stations. The original films from the same cases were subsequently interpreted, usually by another radiologist. The initial and final interpretations were compared. Discrepancies were rated and adjudicated by another senior radiologist. These data were compared to peer review interobserver discrepancy rates. Among the 2688 teleradiology examinations evaluated, there were major discrepancies in 31 (1.5%). In three instances teleradiology rather than film interpretation was considered correct. Abnormalities missed on teleradiology were apparent in all but two at adjudication. Among the 628 peer-review cases, there were 6 (0.96%) major discrepancies. Major teleradiology discrepancy rates are statistically similar to film-based peer review discrepancy rates. Teleradiology is suitable for providing radiologic services to remote medical facilities.
