Study Determines Breast-Specific Gamma Imaging Is More Effective Than Ultrasound in Patients With Complex Breast Tissue

WASHINGTON, Oct. 6 /PRNewswire/ -- Results of a study on Breast-Specific Gamma Imaging (BSGI) presented at the annual breast meeting of the American Society of Clinical Oncology in Washington, D.C., showed that BSGI was nearly twice as effective in finding cancers and more than three times as likely to lead to the correct diagnosis when compared to ultrasound.

Breast-specific gamma imaging (BSGI) is a molecular breast imaging technique being used more frequently as a diagnostic tool in breast centers across the nation. BSGI complements the anatomical imaging of mammography and is performed using an injection of the radiopharmaceutical Sestamibi, an imaging agent that when paired with breast-optimized gamma cameras helps determine the function of breast tissue.

A dedicated breast surgeon in Philadelphia, Dr. Ann Rosenberg, was the lead author on the retrospective, multicenter study. Rosenberg and her group compared the results of BSGI and ultrasound in patients who had dense breast tissue and a remaining diagnostic concern after mammography. The study was performed using a Dilon 6800 Gamma Camera with the standard recommend dose of approximately 20 millicuries of Sestamibi. The results show that BSGI was nearly twice as effective in finding cancers and more than three times as likely to lead to the correct diagnosis when compared to ultrasound.
