What is BSGI? What is MBI?

Molecular Breast Imaging (MBI), also known as Breast-Specific Gamma Imaging (BSGI), is advancing the early detection of breast cancer, especially in difficult-to-diagnose patients. As an adjunct to mammography, MBI utilizes the Dilon 6800® Gamma Camera to help physicians see the breast more clearly and differentiate benign from malignant tissue.

What is MBI? What is BSGI?


The Procedure

The Dilon 6800® Gamma Camera is a high-resolution, small field-of-view gamma camera, optimized to perform MBI. MBI with the Dilon 6800 system can help you:
With MBI, the patient receives a pharmaceutical tracing agent that is absorbed by all the cells in the body. Due to their increased rate of metabolic activity, cancerous cells in the breast absorb a greater amount of the tracing agent than normal, healthy cells. Therefore, malignant cells generally appear as “dark spots” on the MBI/BSGI image.

MBI has very high sensitivity for identifying earlier stage cancers and clinically observed as small as 1 mm; and with a Negative Predictive Value (NPV) comparable to MRI.


  Molecular Breast Imaging (MBI) aids in the effective management of suspicious and difficult-to-interpret breast cases.


MBI with the Dilon 6800:

  • significantly aids in the differentiation of benign and malignant tissue
  • results in lower false positive rates with fewer patient restrictions than MRI
  • is sensitive to small non-palpable lesions
  • provides very high sensitivity for detecting DCIS and lobular carcinomas
  • helps evaluate the need and localize areas of interest for biopsy
  • aids in determining the extent of disease
