In this study we present a case report of pediatric hand x-ray examination. For some reason at times false estimation of the Region-Of-Interest leads to false reconstructions of the final x-ray image and to a retake. The reason for this behaviour is still not definitely clear due to its randomly distributed occurence.
But since we could identify this problem for just one x-ray system only - each pediatric hand x-ray are taken with this system the flat panel detector surface will be covered with an...
Description of activity and work performed
Approx. 180 hand x-ray eximinations per year performed on patients under the age of 10 years and 20 patients under the age of 5 years on a Samsung XGEO GC80 x-ray system.
The standard hand examination procedure is performed with the flat panel detector positioned on the patient table and the patient hand on the detector. These routine exams are performed at tube voltages of 56-59kV and a current-time-product of 1,60 mAs with a Dose-Area-Product of 2...5 mGy*cm².
At times some examinations leads to false...
Conclusion and recommendations
Several attempts are made to avoid these re-takes of radiologic images (additional 5mGy*cm²) but a clear identification when bad images are reconstructed or not could not be definitely estimated.
Since the source for this false image reconstruction is still not clear (even after the manufacturer was involved), we decided to perform every pediatric hand x-ray of patients below the age of 10 years with covering the flat panel detector (left and right beside the hand) of the Samsung system with small lead protection devices such...
