Multi-parametric Breast Ultrasound Imaging as a Potential Biomarker for Breast Cancer
Multi-parametric Breast Ultrasound Imaging as a Potential Biomarker for Breast Cancer
It is studied whether multi-parametric biomarkers such as speed-of-sound imaging or others,
 applied during breast ultrasound (BUS) imaging allows to classify lesions according to its
 malignancy. The standard reference intervention is BUS guided biopsy or the consensus of the
 board of experts judging the BUS imaging results if no biopsy is done.
Patients with a palpable lump in the breast or suspicious findings in X-ray mammography
 typically undergo breast ultrasound examination as a supplemental imaging modality. Findings
 are then used for tumour classification according the American Collage of Radiology (ACR)
 Breast Imaging Reporting and Database System (BI-RADS) lexicon. Suspicious findings then
 undergo ultrasound-guided biopsy, which causes discomfort for the patient and introduces high
 emotional stress, and may involve - albeit very-small - risk of complications (such as
 bleeding and infections).

 Today conventional breast ultrasound B-mode images do not have the specificity to reliably
 differentiate malignant and benign tissues in all cases and hence a biopsy intervention or
 close follow-up is necessitated. Multiparametric imaging bio-markers such as the novel method
 of speed-of-sound imaging may provide additional indicators to help to better classify
 lesions prior to biopsy and avoid any further work-up.

 The study collects data with an ultrasound device during normal BUS examination which is then
 retrospectively processed to extract the desired multi-parametric BUS (mp-BUS) information of
 imaged tissue.
