Abstract/OtherAbstract:
The effect of different processing conditions on the sensitometric characteristics of mammographic films was investigated and the implications of this effect on clinical practice are discussed. Three Agfa (MR5-II, HDR and HT), two Kodak (MinR-M, MinR-2000), one Fuji (AD-M) and one Konica (CM-H) single emulsion mammographic films were used. For each film type a 21-step sensitometric strip was developed in seven different processing conditions involving the use of four processors, five developing times and four chemistries. The different processing conditions produced a variable effect on the sensitometric characteristics of the mammographic films. While some films seemed relatively insensitive, others were greatly affected. Furthermore, not all the sensitometric parameters of a film were affected in the same way. For example, a change of processing conditions in some cases increased speed and decreased contrast but in some other cases increased both speed and contrast. Different mammographic films present different sensitometric characteristics that can be altered by processing conditions. Thus, in a mammographic facility any change in film processor/processing cycle or chemistry should be carefully investigated before mammograms of patients are acquired. Furthermore, the results of film comparisons under certain processing conditions should not be generalized to other processing conditions.
