Storage Phosphor System

Purpose: Chest radiographs from 3 digital systems − 2 based on luminescent phosphors and one on selenium — and a conventional film-screen system were evaluated and compared. Material and Methods: Computed radiography (CR) has for the past years been dominated by a single manufacturer, but now several systems have been marketed. Using a chest phantom and, as test objects, 2 simulated tumours for the lung and mediastinum, respectively, and one object simulating pulmonary lines, a total of 400 exposures were made, 100 on each system. The test objects were placed randomly with a ratio of presence/absence of each object of about 50. Six radiologists participated, 2 residents and 4 staff members. A receiver operating characteristics (ROC) analysis was performed with construction of curves, and the difference between the curves was estimated with a 2-tailed paired t-test. Results and Conclusion: The selenium-based system performed significantly better for pulmonary line detection than all the other systems, and better than one storage phosphor system for the lung “tumour” (p<0.05), while one storage phosphor system was slightly better than the other in diagnosing all 3 test objects. The score for the film-screen system was only average.
