The sensitivity of conventional mammography (MMO) is poor in women with mammographically dense breast parenchyma. We have developed Molecular Breast Imaging (MBI) - a new technique which utilizes a Cadmium-Zinc-Telluride (CZT) gamma camera for scintimammography that has a high sensitivity (~90%) for the detection of breast cancers independent of breast density.
The aim of this study is to demonstrate the utility of MBI as an adjunct screening modality for the detection of occult breast cancers in women with mammographically dense breast tissue. The study will comprise 3500 women. Initial recruitment will be from the pool of patients awaiting a screening mammogram in the Department of Radiology at Mayo Clinic Rochester. All patients will have a screening MMO and an MBI study. Patients with positive studies (MBI or MMO) will undergo additional diagnostic studies. At 15 months post-recruitment, all patients will be contacted by phone or mail to determine whether subsequent to their study, there has been any change in their breast status.
- Past prior SM interpreted as negative or benign (MUST BE PREFORMED AT MAYO CLINIC ROCHESTER)
- Past prior SM interpreted as heterogeneously dense or extremely dense (MUST BE PREFORMED AT MAYO CLINIC ROCHESTER)
- Age 40 or older
- They are unable to understand and sign the consent form
- They are pregnant or lactating
- They are physically unable to sit upright and still for 40 minutes.
