Advantages of a 400 speed image receptor system for cast radiography

By using a faster intensifying screen as opposed to the traditional extremity system for cast radiography, one can reduce the dose to the patient significantly while maintaining quality cast radiographs. In this study a 400 speed Lanex Regular, TMG film system was compared to a 100 speed Lanex Fine, TMG film system. The findings suggest that slow speed, high resolution systems are unnecessary for cast radiography. Evidence demonstrated reduced patient exposure and suggested decreased motion and increased tube life as a result of shorter exposures.
