MONITOR FINDINGS OF DIGITALIZED CONVENTIO NAL WRIST X-RAYS

The study aimed at proving the reliability of monitor systems with the matrix of 1024 x 768 for the detection of scaphoid fractures compared to conventional X-ray. Moreover, we were interested in the significan ce of procedures of digital imaging post processing, depending in part icular on the experience of investigators. 5 investigators with differ ent levels of experience analysed 57 X-rays of the wrist. They compare d conventional X-rays with images on a high screen monitor system afte r the digitalisation of these X-rays by a CCD-scanner and analysed unt reated and treated images. A 5-point scale ROC analysis was used for e valuation. The analysis covered a total of 1740 evaluations. The untre ated images seen on the monitor system proved slightly better than con ventional X-rays. Post-processing has no evident advantage over untrea ted images. Differing levels of experience had no effect whatsoever on the identification of findings.
