[A comparison of digital radiography and conventional x-ray diagnosis for shoulder arthrography]

Fifty double-contrast arthrographies of the shoulder were obtained using conventional film-screen methods as well as by digital luminescence radiography (DLR). The supplied picture-evaluation programs had to be modified and improved prior to this study. In DLR two different post-processed images were obtained, one resembling a conventional film-screen, the other with an intensified edge-enhancement. Some of the digital luminescence radiographs were exposed with only 50% of the conventional doses. A comparison showed the equivalent diagnostic values of both the improved DLR and the conventional film screen. Even a reduction of the exposure dosage did not lead to a loss of information.
