Primary Outcome Measures:
  • Evidence of disease confirmed by surgery, or benign disease confirmed by biopsy [ Time Frame: 30 days ] [ Designated as safety issue: No ]

Enrollment: 40
Study Start Date: May 2008
Study Completion Date: February 2014
Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   18 Years to 90 Years
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Patients that are scheduled for a biopsy at the Mayo Clinic in Rochester, MN. The patients must have a suspicious lesion


Inclusion Criteria:

  • Have a lesion on mammogram, ultrasound or breast MRI that measured < 15 mm in diameter, is considered suggestive or highly suggestive of malignancy according to the Breast Imaging Reporting and Data System Atlas criteria (BIRADS 4b, 4c or 5), and is scheduled for biopsy (needle biopsy and/or surgical biopsy).


  • Have a lesion on mammogram, ultrasound or breast MRI that measured > 15 mm in diameter, is known to be malignant and is scheduled for surgery.
  • Patient age > 18 years of age.
  • Have a negative pregnancy test on the first day of the study, or must be postmenopausal or surgically sterilized.

Exclusion Criteria:

  • Patients will be excluded if they have a small lesion (< 15 mm) and have undergone prior needle biopsy of the lesion (such biopsy may effectively remove all or part of the lesion and angiogenesis associated with wound healing might confound imaging results with 99mTc-NC100692).
  • Patient's pregnancy is not negative on the first day of the study, or the patient is unable to complete the pregnancy test
  • Patient is unable to sit on a chair for 40 minutes
