Scintimammography

Scintimammography is a type of breast imaging technique that uses radioactive tracers to detect breast cancer. It is also known as molecular breast imaging (MBI) or breast-specific gamma imaging (BSGI).

Procedure

The procedure involves injecting a small amount of a radioactive tracer into the patient's vein. The tracer travels through the bloodstream and is absorbed by different tissues in the body. Cancer cells, which are more active than normal cells, absorb more of the tracer. A special camera then takes pictures of the breast, showing areas where the tracer has been absorbed. These areas show up as "hot spots" on the images and may indicate the presence of cancer.

Uses

Scintimammography is used when other imaging tests are inconclusive. It can help to distinguish between benign (non-cancerous) and malignant (cancerous) lesions. It is also used to evaluate suspicious areas found on a mammogram or ultrasound, and to assess the extent of cancer in women who have been newly diagnosed with breast cancer.

Advantages and Disadvantages

The main advantage of scintimammography is that it can detect cancers that are not visible on a mammogram, especially in women with dense breast tissue. However, it is not a replacement for mammography, but rather a supplemental tool. The main disadvantage is that it uses radiation, which can increase the risk of developing cancer.
