Brief Summary
This trial is a study of 20 women with breast cancer to evaluate the addition of MR-guided (MRg) near-infrared spectroscopy (NIRS) with and without contrast, as part of a program to improve clinical management of women receiving breast magnetic resonance imaging (MRI).

Outcome Measures
Primary Outcomes (1)
Optical sensitivity of the MRg-NIRS platform
Optical data sensitivity will be measured (The sensitivity of the measurements to a given region identified by MRI, Sr, will be calculated as the sum of the log of the Jacobian times vector r. Here, r is a logical vector that identifies points within the region of interest and J is the Jacobian, the rate of change of measurements to a change in optical properties at a location in the region identified).
up to one hour on day of MRI
Secondary Outcomes (1)
Diagnostic performance of the MRg-NIRS platform
up to one hour on day of MRI
Study Arms (1)
MR-guided NIRS
OTHERThe MRg-NIRS device will be tested to see if it accommodates different breast sizes, covers the breast fully, includes the axilla, is compatible with commercial breast MRI coil and/or biopsy systems, and the signal-to-noise ratio is high enough for MRg-NIRS image reconstruction. The study team will collect MRI-derived ROI data with T1, T2 and DCE-MRI sequences from 20 women with breast abnormalities and NIRS data concurrently. The study team will also collect diffuse optical signals at 48x48 detector source positions over one side of breast at 6 wavelengths.
Interventions
The trial tests the investigator designed and developed Magnetic Resonance-guided (MRg) Near-infrared Spectroscopy (NIRS) imaging system for breast cancer detection. The wearable NIRS imaging system uses 8 flex circuit strips, each with six photo-detectors (PDs) and six source fibers, that are ready to attach to a breast radially by using an adhesive nipple cover and breast tape.
Eligibility Criteria
You may qualify if:
- Females age ≥ 18 years old
- Participants capable of providing written informed consent
- Women with a recent diagnosis of breast cancer.
- Women who are in pre-surgical planning must have an estimated tumor size of 2.0 cm or less on available imaging.
- Women who are in pre-surgical planning must have had a breast biopsy at least 10 days prior to the MRg-NIRS exam.
You may not qualify if:
- Participants with absolute or relative contraindication to MRI:
- the presence of an electronic implant, such as a pacemaker
- the presence of a metal implant, such as an aneurysm clip
- claustrophobia
- renal failure (FDA's guidance for gadolinium of a creatinine clearance less than 30 mL/1.73 m2 BSA)
- Pregnant women
- Breast implants
- Prisoners
- Participants with visually inadequate healing from breast biopsy.
