DIGITAL FLUOROSCOPIC RADIOLOGY - EVALUATION OF THE CLINICAL IMPACT

The use of digital image intensifier radiography (DIIR) for examinatio ns in projection radiography is becoming more common. Fluoroscopic con trolled contrast studies (barium- or iodine-based), particularly of th e gastrointestinal tract, can be performed quickly and easily with a c onsiderable decrease in radiation exposure. A wide dynamic range permi ts a constant high image quality with fewer incorrect exposures. The l imited spatial resolution of large image intensifier input screens is the major drawback of DIIR. Digital image acquisition enables post-pro cessing, digital storage and transfer of images, thus allowing an inte gration into PACS-systems. Imaging capabilities and clinical applicati ons are described here.
