# Quantitative Volumetric Analysis Using 3D Ultrasound Tomography for Breast Mass Characterization

## TL;DR

This study explores a new 3D ultrasound imaging method for detecting and characterizing breast masses as an alternative to traditional mammography.

## Contribution

The study introduces QT3D as a novel non-invasive imaging modality for breast mass characterization.

## Key findings

- QT3D can detect small tumors, multiple lesions, satellite lesions, intraductal extensions, and calcifications.
- The method offers diagnostic insights comparable to MRI for breast mass characterization.

## Abstract

Breast cancer detection remains a significant challenge, with traditional mammography presenting barriers such as discomfort, radiation exposure, high false-positive rates, and financial burden. Moreover, younger women frequently fall outside routine mammographic screening guidelines, leaving critical gaps in early detection. Objectives: This study investigates the potential of quantitative transmission breast acoustic computed tomography scanner imaging (QT3D) as an innovative, non-invasive imaging modality for characterizing and evaluating breast masses. Methods: A comparative analysis between QT3D imaging and magnetic resonance imaging (MRI) was conducted in a cohort of patients with biopsy-proven benign or malignant breast lesions, comparing key metrics in quantifying breast masses for the purposes of breast mass characterization. Results: The findings in this study highlight its capability in identifying relatively small tumors, multiple lesions, satellite lesions, intraductal extensions, and calcifications, in addition to offering valuable diagnostic insights. Conclusions: This work is a first step toward studies essential for confirming its clinical feasibility, establishing its role in breast cancer tumor characterization, and potentially improving patient outcomes.
