Molecular breast imaging is also known as breast specific gamma imaging or BSGI. Molecular breast imaging is promising as it can find cancers with a sensitivity of less than 3mm (this is better than MRI). The drawback is the high level of radiation currently associated with MBI. There are many centers working on the technology of MBI to get the radiation level of MBI to an acceptable dose. I look forward to this advancement as I feel it would be an excellent, more sensitive screening test once the radiation level is lowered. Here is my overview of BSGI.
BSGI stands for breast specific gamma imaging. BSGI is a fairly new technique that involves injecting a radioactive substance technetium (t-99) into a patient's veins and then scanning their breast with a gamma camera.
The gamma camera takes images of the breast and the areas where the radioactive substance has concentrated (this may indicate a breast cancer) will show up darker.
Pros of BSGI are increased sensitivity for detecting tumors at a smaller size than other available imaging techniques.
Cons of BSGI are the higher amount of radiation the person is exposed to during the test.
Some considerations: This test is reasonable for a person to have performed if they are first diagnosed with breast cancer to assess for occult cancers in either breast. Another scenario is a person who cannot have an MRI but requires a more sensitive test. Currently this is NOT a test for women to have yearly, too much radiation!
