Purpose: A radiography system especially developed for specimen radiography and allowing maximal
20-fold magnification is presented. The efficiency of the system was tested and compared
with that of conventional magnification mammography systems. Methods: Twenty-three surgical and 90 core biopsies of the breast were examined for detection
of microcalcifications. As criteria the number of identifiable calcifications, their
shape and configuration as well as tissue contrast were chosen. Results: The new technique detected about 40% more microcalcifications, 20% more and 50% more
surgical biopsies containing calcifications. Thus, in a few cases, additional core
biopsies were unnecessary. Moreover, this new system yielded additional information
for the pathologist and surgeon concerning the exact location of suspicious lesions
that facilitated working up specimens, or indicated additional surgical removal in
special cases. Conclusions: By identification of malignant lesions not detectable with conventional magnification
radiography systems, as well as a more exact localization of suspicious lesions, false-negative
results may be reduced.
