Multi-parametric Breast Ultrasound Imaging as a Potential Biomarker for Breast Cancer

Overview

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.
