This is a pilot study to evaluate 2D contrast-enhanced mammography image and 3D (tomosynthesis) contrast-enhanced images to contrast enhanced MRI in women with greater than 95% probability of breast cancer (BIRADS 5) or confirmed breast cancer (BIRADS 6).This study will then be used to design additional studies.

Primary Outcome Measures:
  • A PILOT study to determine Cancer lesion enhancement with CEM and CEBT is non-inferior to that of CEMRI. [ Time Frame: Fall 2012 ]

    This Pilot study is designed to evaluate two x-ray contrast methods with contrast enhanced MRI. Each subject will be imaged with CEM, CEBT and CEMRI. The goals for this will be to:

    i) Using a Likert scale, Compare the enhancement of breast cancer lesions with CEM, CEBT and CEMRI.

    ii) Using a Likert scale, Compare the enhancement of benign breast lesions with CEM, CEBT and CEMRI.

    The results of this study will be used to design studies to measure the sensitivity and specificity of CEM and CEBT.

Secondary Outcome Measures:
  • Comparison of lesion conspicuity [ Time Frame: up to one year post study enrollment ]
    Using a Likert scale the CEM and the CBT images will be compared with standard pre-contrast mammography and tomosynthesis images to determine lesion conspicuity.

Enrollment: 30
Study Start Date: July 2011
Study Completion Date: February 2014
Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
Contrast-enhanced Mammography
Subjects will undergo 2D imaging with iodine contrast.
Contrast-enhanced Breast Tomosynthesis
Subjects will undergo 3D imaging with iodine contrast.
Contrast-enhanced MRI
Each subject imaged with iodine contrast will also be imaged with contrast-enhanced MRI using gadolinium.

  • >50% of the biopsied cancer mass must remain following biopsy OR
  • A calcification must be at least 2cm in maximum dimension prior to biopsy or at least 1cm in maximum dimension following biopsy

  • Subject has a documented renal insufficiency,
  • Subject requires renal dialysis.
  • Subject has had a prior reaction to iodinated contrast.
  • Subject has had a prior episode of anaphylactic reaction to any substance.
  • Subject has taken metformin (Glucophage) within 48 hours of study procedures.
  • Subject has multiple allergies and/or severe asthma regularly treated with medication (prescription and/or over-the-counter).
