[Reduction of radiation dosage in mammography by using film intensifying foil systems in Poland].

In order to assess possibility of radiation dose reduction during mammography at direct film radiation, a comparative studies have been carried out. The studies involved Roentgen XT-2 film without intensifying foil compared with Mammoray MR-3 (Agfa Gevaert), Ortho M-MO-1 (Kodak) in the original cassettes, and Fluorfilm TK-1 (WZF Foton) with foils Min.-R. Film-intensifying foil systems are four and six times more sensitive than Rentgen XT-2 film. Sensitometric and diagnostic properties of Fluorofilm TK-1 are comparable with Mammoray MR-3 film. Therefore, films Rentgen XT-2 which are presently used in mammography should be replaced with Fluorofilm TK-1 with the intensifying foils.
