The relative quality and speed of a new ultraviolet‐emitting screen, ultraviolet‐sensitive film rare‐earth system (DuPont Ultra‐Vision®) was compared to an orthochromatic rare‐earth system (Kodak Lanex®) in a clinical trial. Seven different sets of radiographs of a human foot phantom, or actual canine anatomical structures (tarsus, pelvis, skull, chest, abdomen) were evaluated independently by radiologists, radiology residents and technicians who were unaware of the screen/film combinations used. The 400‐speed, Ultra‐Vision® Rapid/UVG screen/film combination produced supervisor image detail compared to blue/green emitting 400 and 200‐speed screen/film combinations. The image detail of the Ultra‐Vision® Rapid/UVG system was nearly equivalent to that produced using a 100‐speed, fine‐detail blue/green emitting screen/film combination. A 200‐speed Ultra‐Vision® system was also tested and produced thoracic and abdominal radiographs of equivalent to slightly supervisor quality than those produced using blue/green emitting system.
