MRg-NIRS Imaging System Breast Cancer Trial

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).

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • 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.

Exclusion criteria

  • 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.

Treatment and study plan

MRg-NIRS

Device

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.

Other names: MR-guided NIRS Data Collection

Primary outcomes

  1. Optical sensitivity of the MRg-NIRS platform

    Time frame: up to one hour on day of MRI

    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).

Secondary outcomes

  1. Diagnostic performance of the MRg-NIRS platform

    Time frame: up to one hour on day of MRI

    Diagnostic performance will be measured in terms of sensitivity, specificity and area under the receiver-operator characteristic curve (ROC).
