[Digital luminescence radiography in comparison with the conventional film-screen technique in diagnosis of fractures].

PURPOSE

The accuracy of digital luminescence radiography was compared with that of conventional film/screen techniques, using animal preparations and clinical examinations.

MATERIAL AND METHOD

Fine fissures were made in 8 animal bones and these were examined radiologically. The digital examinations were carried out with and without edge enhancement. 208 patients were examined in a similar way. Film quality and assessment of the fractures were evaluated quantitatively.

RESULTS

In no instance did either of the digital methods provide inferior quality when compared with conventional films. ROC analysis for evaluation of fractures in patients, using an experienced radiologist, showed no significant difference between the various methods (ROC areas: conventional 0.947, digital 0.958, digital with edge enhancement 0.943). With a less experienced observer there were significant advantages for both digital methods (ROC areas: 0.851, 0.886, 0.908).

CONCLUSION

Our investigation has proved that fractures which are difficult to see can be reliably demonstrated by digital luminescence radiography.
