Clinical trial of digital teleradiology in the practice of emergency room radiology.
The application of digital teleradiology (DTR) to radiologic examinations performed in the emergency room was evaluated. A total of 919 examinations (ten computed tomographic; the rest, radiographic) were transmitted to a radiology resident at another hospital emergency room. The 512 X 512 images were reviewed by an attending radiologist and compared with another attending radiologist's interpretation of the original films. Cases with discrepant interpretations were analyzed. Inadequate DTR image quality was responsible for clinically significant discrepancies in 14 of 897 cases (1.6%) available for follow up. Problem areas such as the detection of pneumothorax and abdominal calcifications were identified. Retransmission of optically zoomed images of areas of concern and repeat radiographs of overpenetrated films are suggested to improve DTR performance.
