Printed radiographs--is what you see what you get?

UNLABELLED: Digital dental radiography allows for exchange of images between primary and secondary care. However, it is common practice for radiographs to be printed out and attached to referrals.This study investigates the loss of diagnostic information of printed radiographs compared to the on-screen digital image.The best quality was achieved with images printed onto radiographic film or onto photographic paper with an inkjet printer. Laser and inkjet printer output onto 80 gsm office paper resulted in a loss of diagnostic information. Wherever possible, radiographs should be transmitted digitally between clinicians to maintain image integrity. CLINICAL RELEVANCE: This paper illustrates the potential pitfalls of printing radiographs to be sent with referrals.
