Brief Summary
Imagio breast imaging system, is an opto-acoustic (OA) imaging system designed to concurrently collect images in conjunction with diagnostic ultrasound ( co-registered OA and B-mode imaging). This medical device has CE-marking and is approved for use in Europe and other nations. This is a post-market, non-randomized multi-center surveillance study.

Outcome Measures
Primary Outcomes (2)
OA/US Specificity (Downgrade (%) for BI-RADS 4A & 4B) of Benign Masses
Outcome is the percentage of benign masses correctly downgraded by (OA/US) ultrasonography from a suspicious abnormality (4A or 4B) to benign or probably benign (BI-RADS 2 or 3). BI-RADS is the Breast Imaging Reporting and Data System established the American College of Radiology. BI-RADS scores range from 0 to 6, with increase in score indicating an increase in the probability of malignancy. A BI-RADS score of 4 or more indicates the need for biopsy. Specificity is reported with a 96% confidence interval using a normal approximation.
CDU images and decision to biopsy to be done at Screening. OA/US imaging to be done within 10 days of Screening. Biopsy to be done within 30 days of Screening.
OA/US Sensitivity (Upgrade (%) for BI-RADS 4A & 4B) of Malignant Masses
Outcome is the percentage of malignant masses correctly identified by (OA/US) ultrasonography as BI-RADS 4a or higher. BI-RADS is the Breast Imaging Reporting and Data System established the American College of Radiology. BI-RADS scores range from 0 to 6, with increase in score indicating an increase in the probability of malignancy. A BI-RADS score of 4 or more indicates the need for biopsy. Sensitivity is reported with a 96% confidence interval using a normal approximation.
CDU images and decision to biopsy to be done at Screening. OA/US imaging to be done within 10 days of Screening. Biopsy to be done within 30 days of Screening.

Eligibility Criteria
You may qualify if:
- Female
- years of age or older
- Have an undiagnosed suspicious finding which may include more than one solid or complex cystic suspicious mass, classified by CDU as BI-RADS 4a or 4b within 3 weeks of their baseline Imagio Scan
You may not qualify if:
- Have a condition or impediment that could interfere with the intended field of view (within one probe length or 4 cm of the mass), (i.e., breast implants within the previous 12 months, or tattoos)
- Pregnant or lactating
- Patient has received chemotherapy for any type of cancer within 90 days from date of screening CDU
