The new era of breast ultrasonograhpy: High frequency

High-Frequency Ultrasonography is a recent advance in Ultrasonography. It allows improving spatial resolution reducing penetration of ultrasound beam. This facility allows studying more accurately cutaneous diseases, blood vessels wall and eyes anatomy. However it could be useful also to evaluate breast superficial lesion, cutaneous involvement in breast cancer and several cutaneous diseases of nipple and breast. In our experience, HFU allows optimal definition of cutaneous layers of pre-mammary zone, when compared to conventional ultrasonography, offering an optimal tool for better assessing superficial layers diseases of breast and pathologies involving pre-mammary zone.
