To evaluate the workflow efficiency between CR vs. wireless flat-panel DR systems for routine checkup Chest posterioranterior (PA) erect position examinations.
On routine checkup Chest PA view erect position. The work flow steps of CR and wireless flatpanel DR system were identified, including examination preparation, patient positioning, exposure, post-acquisition processing and total examination time were recorded. We only included post-acquisition processing time because time from exposure to appearance of imaging is relatively fixed.
A total of 476 patients were examined (CR, n = 244; DR, n = 232). The total time of procedure for CR system was 86.2- 96.2 seconds. For the DR system it was 17.6-19.5 seconds.
Workflow efficiency of DR system is better than CR system in routine chest examination. Modern radiologic departments require a DR system.
