简要总结

This purpose of this clinical study to develop and test technology associated with near infrared (NIR) optical tomography of the breast (the use of light at NIR wavelengths to image the breast) as an adjunct to mammography and breast MRI.

详细描述

The purpose of this clinical study is to demonstrate the feasibility of NIR absorption and fluorescence imaging of the female breast when the method is guided by breast MRI. The hypotheses to be tested are:

  1. MR-guided NIR absorption and fluorescence imaging of the breast is feasible in the setting of a clinical breast exam
  2. MR-guided NIR absorption and fluorescence imaging of the breast provides spatial localization and contrast of a breast abnormality that is superior to NIR absorption and fluorescence tomography alone.

入选标准

  • Female, ≥20 years old
  • Breast size and epithelial integrity adequate to allow NIR imaging exams.
  • Ability to provide written informed consent
  • No serious associated psychiatric illnesses.

排除标准

  • 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
  • the presence of other contraindication(s), as determined by the MRI technologists and radiologists.
  • WOMEN WITH BREAST ABNORMALITIES
  • Female, ≥ 20 years old.
  • Breast size and epithelial integrity adequate to allow NIR imaging exams.
  • Ability to provide written informed consent.
  • No serious associated psychiatric illnesses.
  • A recent screening mammogram that questions the presence of an abnormality, thus requiring further mammographic examination.
  • 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
  • the presence of other contraindication(s), as determined by the MRI technologists and radiologists.
  • A history of allergy to iodides
  • A GFR < 30 ml/min as determined by blood test on the day of NIR/MR imaging, or from lab results within 3 months of NIR/MR imaging.

结局指标

主要结局

Compare spatial localization and contrast images of breast abnormalities from MR-guided NIR absorption and fluorescence tomography to NIR absorption and fluorescence tomography alone

时间窗: During imaging and evaluation by a radiologist or medical technologist, up to 90 minute

Women will participate in MR-guided NIR exams which include both MR and optical contrast agents. These imaging outcomes will be compared to exams where only the MR contrast agent is used as well as to exams where no contrast agents are administered.
