An acceptable mammography film digitizer must provide high-quality images at a level of diagnostic accuracy comparable to reading conventional film examinations. The purpose of this study was to determine if there are significant differences between the interpretations of conventional film-screen mammography examinations and soft copy readings of the images(More)
Forty pneumonia and 40 fracture cases were matched by patient age and gender with normal cases. Pediatric cases constituted 25% of this sample. All 160 examinations were laser-digitized at a spot size of 210 microns, a contrast resolution of 12 bits, and a spatial resolution of 2.35 line pairs per millimeter. The digitized images were transmitted 5 miles(More)
The purpose of this study was to evaluate whether radiologists perform equally well with plain radiographs or digitized images displayed on a video monitor in interpretation of difficult orthopedic trauma cases. Interpretations with film and those made from a teleradiology system with spatial resolution of 2.35 line pairs per millimeter were compared in 120(More)
PURPOSE To compare accuracy of interpretation by radiologists and emergency medicine physicians of conventional radiographs and digitized images on a workstation. MATERIALS AND METHODS One author selected 120 radiographs from the radiology department library, including 62 musculoskeletal, 20 abdominal, and 38 chest examinations. Analog radiographs were(More)
OBJECTIVE We determined the relative value of teleradiology and radiology resident coverage of the emergency department by measuring and comparing the effects of physician specialty, training level, and image display method on accuracy of radiograph interpretation. MATERIALS AND METHODS A sample of four faculty emergency medicine physicians, four(More)
A laboratory evaluation of a microcomputer-based teleradiology system is described. The system used state-of-the-art hardware, and provided for contrast and brightness control by the consulting radiologists. The transmitted, digitized images were compared with conventional radiographs. The radiologists' scores for findings, impressions, and confidence(More)
A microcomputer-based teleradiology system was tested over a six-month period by linking a medical center with four distant clinics. Data from more than 4,000 diagnostic x-ray examinations were digitized and transmitted from the clinics to the center, where they were displayed on video terminals and interpreted by 30 military and civilian radiologists. The(More)
Automated medical communication systems for patient care usually enhance timeliness and retrievability. The effect of automated systems on communication quality has not been sufficiently measured. The radiology reports produced with the automated radiology reporting system at the Johns Hopkins Hospital were evalueate for quality and compared to reports(More)
Careful planning of the study and full support of the radiology staff are essential for collection of such data. It important to obtain pilot data to identify potential problems and adequately train personnel. Such pilot data should be compared with data collected automatically from the HIS, RIS, or PACS to establish the reliability of various data sources.(More)
