Paper Abstract

Evaluation of radiologist and non-radiologist physician acceptance of computed radiography (CR) as an alternative to film-based radiography in an emergency department (ED) is performed. All emergency department radiographs are performed using photostimulable phosphor plates and rad by a computed radiography laser reader placed in the former emergency department darkroom. Soft copy images are simultaneously transmitted to high- and medium-resolution dual-monitor display stations located in radiology and ED reading rooms respectively. The on-call radiologist is automatically paged by the Radiology Information System (RIS) upon exam completion, to read the new ED imaging study. Patient demographic information including relevant clinical history is conveyed to the radiologist via the RIS. A 'wet read' preliminary radiology report is immediately transmitted back to the ED. Radiology and ED physicians are surveyed to ascertain preferences for CR or traditional screen-film, based on system implementation, image viewing and clinical impact issues. Preliminary results indicate a preference for filmless CR among the ED physicians if digital reliability and speed issues are met. This preference appears to be independent of physician level of experience. Inexperienced radiologists-in-training appear to have less comfort with softcopy reading for primary diagnosis. However, additional training in softcopy reading techniques can improve confidences. Image quality issues are most important tot he radiologist, while speed and reliability are the major issues for ED physicians. Reasons for CR preference include immediate access to images on display stations, near-zero exam retake rates, and improved response time and communication between radiology and the emergency department clinician.
