The objective of this study was to evaluate the image quality and dynamic range of two digital radiographic storage phosphor systems: Digora (Soredex, Finland) and DenOptix (Gendex, USA). Four objects were analyzed and eight exposure times employed, totaling 64 images that were analyzed by 5 examiners using a scale from 1 to 4 to classify the images. The scores were submitted to analysis of variance and the results showed statistical differences among the averages attributed to the systems, to the exposition times and to the objects (p 0.01 Pound). Digora presented a larger dynamic range and, in general, a better image quality. Although these 2 systems present the same photon detector, they present different results in relation to the evaluated items.
