[Comparison of xeroradiography and photographic radiography in the study of breast pathology].
The peculiar characteristics of xeroradiography make it respond fully to the requirements of the radiographic represenattion of the breast. All the anatomical components of the breast are virtually identical as far as atomic number and low density are concerned. Xeroradiography has proved to be particularly suitable for highlighting the little difference in contrast between the various anatomical components of the breast. Pictures show the quality differences between traditional photographic mammography and xeromammography. The latter differs by its high power of resolution at all contrast levels thus making for easier identification of details and clearer outline, and by its broader exposure latitude making it possible to focus on a wider range of tissues. Visualization of dense, compact, youthful breasts [so-called opaque breasts] is also more reliable. Density differences can be exploited more effectively in cases of concomittance of two or more pathological situations such as: association of two mastopathic pictures, the presence of a small benignant formation or of a heteroplasia within an intensely dysplasic region. Thanks to a more smaller than immediate greater than interpretation of the picture, xeromammography also provides clearer evidence of the radiographic signs typical of benign neoformations and those typical of malignant forms.
