About this study

The purpose of this study is to show that improvements in the molecular breast imaging (MBI) technology will allow reduction of the administered dose of Tc-99m sestamibi while maintaining a sensitivity of 90% for tumor detection.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

  • Patients referred for a mammogram, ultrasound or breast MRI study at Mayo Clinic Rochester will be considered for the study if they meet the following criteria:
  • Have a lesion on mammogram, ultrasound or breast MRI that measured < 2 cm and is considered suspicious or highly suggestive of malignancy according to the Breast Imaging Reporting and Data System Atlas criteria (BI-RADS 4 or 5). (Note: while 2 cm is larger than the desired lesion size that we wish to study, this limit was recommended by our radiology colleagues as estimates of lesion size from mammography, ultrasound and MRI are not exact)
  • Are scheduled for biopsy (needle and/or surgical biopsy) of the suspicious lesion
  • Are > 18 years of age
  • Had a negative pregnancy test or must be postmenopausal or surgically sterilized
