M.D. Anderson Cancer Center
To evaluate the diagnostic performance of Tc99m sestamibi (MBI) compared to breast MRI in women who are at high risk for developing breast cancer. To assess the relationship of tumor size, histologic subtype and location of lesion and how it affects lesion conspicuity and sensitivity in MBI detected cancers.
Primary Objective: -To compare the diagnostic performance of Molecular Breast Imaging (MBI) to breast Magnetic Resonance Imaging (MRI) in women who are at high risk of developing breast cancer. Secondary Objectives: * To evaluate the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of MBI compared to breast MRI in women who are at high risk of developing breast cancer. * To assess patient preference for the two examinations by conducting a post examination survey and follow up questionnaire (see addendum). * To assess the relationship of tumor si…
Inclusion Criteria: * The subjects to be studied will include female patients ages 18 and older of any race, identified as carrying an elevated risk for breast cancer referred to MDACC. * High risk may be defined as having a calculated lifetime risk \>20%, histopathology of lobular neoplasia or atypical ductal hyperplasia, atypia NOS or a genetic mutation known to predispose the patient to breast cancer. * Subject who are scheduled for a Breast MRI who are willing to participate fully in all aspects of the study including completing both a Breast MRI \& MBI screening exam within a two-week ti…
