Summary
Brief summary (as posted)
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).

- OTHER
- label
- MR-guided NIRS
- description
- The 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.

Primary outcomes (1)
- measure
- Optical sensitivity of the MRg-NIRS platform
- timeFrame
- up to one hour on day of MRI
- description
- 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).
