Radiographic film fog artifact caused by fluorescent bandage.

Film fog is a common cause of x-ray film artifact. The authors report an unusual source of film fogging in the darkroom--seen in three consecutive radiographs of two different patients--the exposure of film to the low light emission of a fluorescent commercial adhesive bandage worn by the technologist. Heightened awareness of the effects of these bandages will help avoid creation of this film fog artifact.

Modus operandi for a picture archiving and communication system.

The authors describe their 18 month experience operating an all digital nuclear medicine department, which led to the development of a system that allows multiple users to access patient reports and images through terminals located in various parts of the hospital. All user interactions are mediated through protocols that automatically acquire, process, display, and archive data. This approach offers distinct advantages over film and paper methods and is applicable in theory to any digital image format.
