Especially in breast reconstruction after mastectomy, subcutaneous mastectomy, or extensive lumpectomy, the radiological properties of breast implants play an important role. Mammography is still the gold standard for follow-up diagnostics as well as for preventive diagnostics, and the interpretation of these films is greatly influenced by the type of the implant filler material. In this study, in vivo conditions are simulated, and standard mammography techniques applied to examine the effects of various types of implants on the readability of mammography films using semiquantitative measurements as well as subjective judgement by independent radiologists.
