Brief Summary

This clinical trial compares the use of quantitative transmission imaging (QTI) to standard of care MRI as a supplemental screening tool for patients with a high lifetime risk of breast cancer. QTI is a single 3D ultrasound test intended to be used as an initial evaluation method for asymptomatic women identified with above-average risk for developing breast cancer. Using QTI may be an effective supplemental screening tool, compared to MRI for patients with a high lifetime risk of breast cancer.

Conditions

Breast Carcinoma

Outcome Measures

Primary Outcomes (1)

• Number of Findings for the Total MRI Interpretations and Total QTI Interpretations Performed

  Assessed by the number of positive findings. For each finding, imaging characteristics, size, and location were recorded. A Breast Imaging Reporting and Data System (BI-RADS) score was assigned for each finding. If biopsies are obtained, then findings will be compared to histopathologic diagnosis.
