Breast-Specific Gamma Imaging (BSGI)
The Jackson Imaging Center recognizes that breast cancer is highly curable when it is treated in its early stages and always aims for a positive outcome. With BSGI, 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 and generally appear as "dark spots" on the BSGI image. The Dilon 6800 Gamma Camera is a high-resolution, compact gamma camera optimized to perform BSGI.
Mammograms are sometimes difficult to interpret due to dense breast tissue, fibrocystic and other benign conditions of the breast, scarring from a previous surgery, or implants. In these cases, additional testing is often necessary, including ultrasound, MRI or BSGI. Mammography is a highly sensitive screening tool, which means it is very effective in detecting breast abnormalities. However, higher breast density lowers sensitivity. In some cases, traditional anatomic imaging, such as mammography and ultrasound, have low specificity, which is the ability to determine whether an indeterminate area is cancerous or benign. By studying the metabolic activity of the breast tissue, BSGI is useful in these instances.
BSGI with the Dilon 6800 takes about 45 minutes to perform. Because there is no compression of the breast and patients are seated throughout the entire procedure, it is much more comfortable than a mammogram. Insurance companies generally cover BSGI with the Dilon 6800 Gamma Camera.
