Abstract

Mammography remains the gold standard in breast cancer detection, although there remains a challenge for improvement in sensitivity of breast cancer detection and diagnosis. Although mammography is the most frequently utilized examination to screen for breast cancer, which has resulted in a reduction of breast cancer mortality, still some cancers are unable to be visualized on mammographic images. Mammography films are interpreted using an anatomic approach. A new approach to breast cancer diagnosis utilizes a breast specific gamma camera to measure radiotracer uptake of abnormal tissue in the breast in patients with an abnormal mammogram or palpable mass using technetium sestamibi. Images are taken using the same positioning techniques as mammography for comparison of both types of images. Multi-Institutional trials using a traditional gamma camera demonstrated potential for this approach. However, the inability of traditional gamma camera intrinsic resolution and non-optimized breast imaging limited scintimammography. Therefore, a breast specific, high resolution gamma camera was developed to overcome these limitations. Results of clinical studies evaluating BSGI are promising and are increasingly being used. Additionally, means for minimally invasive imaging-guided acquisition of tissue are being developed so that biopsies will be available for areas of interest based on radiotracer uptake. Breast specific gamma camera nuclear imaging of the breast is a developing and increasingly utilized approach to improving breast cancer detection and diagnosis.
