MRg-NIRS Imaging System Breast Cancer Trial

Evaluation of the Magnetic Resonance-guided (MRg) Near-infrared Spectroscopy (NIRS) Imaging System Platform in Breast Cancer Patients

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).

This trial is designed to determine if the MRg-NIRS system will contribute significantly to improved clinical management of women receiving breast magnetic resonance imaging (MRI) by achieving diagnostic performance comparable to or better than dynamic contrast-enhanced (DCE) breast MRI alone.

The purpose of this clinical trial is to evaluate the addition of MRg-NIRS with and without contrast in 20 women with breast cancer. The women enrolled in the trial will be those who have a newly diagnosed breast cancer.

Inclusion Criteria:

1. Females age ≥ 18 years old
2. Participants capable of providing written informed consent
3. Women with a recent diagnosis of breast cancer.
4. Women who are in pre-surgical planning must have an estimated tumor size of 2.0 cm or less on available imaging.
5. Women who are in pre-surgical planning must have had a breast biopsy at least 10 days prior to the MRg-NIRS exam.

Exclusion Criteria:

1. Participants with absolute or relative contraindication to MRI:

   1. the presence of an electronic implant, such as a pacemaker
   2. the presence of a metal implant, such as an aneurysm clip
   3. claustrophobia
   4. renal failure (FDA's guidance for gadolinium of a creatinine clearance less than 30 mL/1.73 m2 BSA)

2. Pregnant women

3. Breast implants

4. Prisoners

5. Participants with visually inadequate healing from breast biopsy.
