Abstract In the course of a comparative study 231 patients with traumatic lesions in skeletal and soft tissue areas were X-rayed using conventional film radiography and digital luminescence radiography (DLR). The results were evaluated by radiologists and traumatologists on the basis of optimised image post-processing in addition to the standard digital presentations. The imaging quality of compacta, spongiosa, soft tissues, fracture lines and osteosynthesis material was assessed in comparison with the screen-film images. Whereas the standard digital presentation in the “conventionally adjusted” imaging mode was inferior to the screen-film radiograph, the “edge-enhanced” standard presentation proved to be advantageous in the imaging of soft tissues (frequency of first-place ratings: DLR conventional 6%, screen-film system 21%, DLR edge-enhanced 31%). In the overall evaluation high-frequency filtered inverse image post-processing showed the highest diagnostic potential (frequency of first-place ratings: 41%). A conclusive assessment of metal implants is hindered by overshoot artefacts and can only be achieved through time-consuming post-processing of the stored image data.
