Abstract
The display of a large number of projection radiographs (e.g., AP chest images) for comparison purposes poses potential problems for any electronic environment. In an attempt to assess the concept of rapid sequential viewing, 10 series of AP chest images were each reviewed on a high-resolution workstation under two conditions: (1) simultaneous display of each series in a mosaic configuration; and (2) separate image display in which each image was viewed individually in a rapid sequential mode. In our study, the sequential display was believed subjectively to be of comparable or higher quality by four of six readers. Diagnostic performance (patient improved; no change; patient condition worsened) was comparable for both display modes. Readers were somewhat more comfortable with the simultaneous (mosaic) configuration. Our preliminary results indicate that after minimal training, rapid sequential viewing of AP-chest images may be a reasonable alternative for the display of a series of AP chest images in the ICU.
