[Digital subtraction discography].
Conventional cervical discography was carried out in 25 patients during the period of one year. At the same time, we employed the well known principle of digital subtraction. The results of DSD have been compared with conventional discography. In every case more informative images were obtained despite the use of lower amounts of contrast. The distribution pattern of the reduced amounts of contrast in the disc provides valuable information. In the shoulder region, great improvement in picture quality is possible. For these reasons, the use of digital subtraction for discography is justified.
