IMAging With Opto-acoustics to downgradE BI-RADS claSsificaTion Relative tO Other Diagnostic Methodologies (MAESTRO) (MAESTRO)
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.

Description
Inclusion Criteria
- Female
- 18 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
Exclusion Criteria:
- 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

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
OA/US Specificity (Downgrade (%) for BI-RADS 4A & 4B) of Benign Masses
Time Frame: 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.
|
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
Time Frame: 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.
|
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.
