[Digital image intensification radiography in endoscopic retrograde cholangiopancreatography]

The standard in ERCP is the use of the conventional radiography system. Digital radiography system are very seldom used in ERCP, and then mostly by digital luminescence radiography. In this study we report our experience with digital image amplification radiography (DIAR) in ERCP. We examined 53 patients of clinical routine aged from 21 to 90 years. During the ERCP we used the X-ray statues and the real-time exposures. At the end of an examination the image post-processing followed. Both conventional and digital image amplification radiography needed the same examination conditions. The special X-ray protection (special lead-shields) used at digital ERCP did not hinder the examination. The DIAR provided at least the same amount of information as conventional radiography. An advantage of DIAR is the possibility of image post-processing such as contrast change, zooming, etc., and the digital archiving and communication. The examination time was reduced by about 30% as compared conventional ERCP, resulting in a reduction of the X-ray exposure time for the patients. The disadvantages of DIAR can surely be compensated by a high ERCP-rate.
