[Microcalcifications in mammography and visualization by ultrasound (author's transl)].

Sonography can yield indirect visualization only of microcalcifications in the female breast. In order to obtain an image of the echo pattern of the grouped microcalcifications, it is essential that the device employed possesses suitable dynamic characteristics, and it is also necessary to employ the technique of additive tomography. The investigator must familiarize himself with the proper interpretation of reflex patterns. Microcalcifications cannot be detected via sonography with the same degree of accuracy as with the help of mammography. However, sonographic detection is easier if the microcalcifications are more closely grouped. Nevertheless, the authors were able to show in a small comparative series that grouped calcifications can be detected even without previous information of their presence.
