Clinical Indications & Advantages
Due to its physiologic imaging capability, Breast-Specific Gamma Imaging/Molecular Breast Imaging (BSGI/MBI) provides improved specificity over MRI while providing images that make interpretation of the study easier for the reader. In addition, BSGI provides physiologic data in the same imaging projections as mammography allowing direct correlation between the two modalities.
BSGI and MRI both provide critical diagnostic information with comparable sensitivity. These two imaging modalities can help guide your efforts to effectively diagnose and plan surgeries.
BSGI advantages relative to MRI include:
- Improved PPV
- Images correlate to all mammographic views and are easy to interpret
- Fewer patient restrictions than MRI, such as: obesity; breast size; ferromagnetic implants; claustrophobia; compromised kidney and/or liver function; etc.
- High sensitivity for DCIS and lobular carcinoma
Additional Advantages for BSGI:
- Assists in the differentiation of scar tissue from a cancer reoccurrence in patients with previous cancer diagnosis.
- Screening high-risk patients. This is particularly useful for patients with elevated risk factors that fail to meet the American Cancer Society guidelines for MRI screening.
- In clinical trials, BSGI has demonstrated the ability to aid in the diagnosis of cancer in patients with factors limiting the utility of mammography such as: dense breasts, implants or injections for augmentation.
- Patients with indeterminate findings and low probability of malignancy needing additional reassurance. For example, patients with BIRADS III findings requiring short-term follow up.
