Molecular Breast Imaging/ BSGI

Dilon brochure

Performed with the Dilon 6800 Gamma Camera, Molecular Breast Imaging (MBI) - also called Breast-Specific Gamma Imaging (BSGI) - is an excellent problem-solving tool for questionable findings on mammography or breast ultrasound. It can also be helpful for evaluating areas of palpable concern when the mammogram and ultrasound are normal.

This molecular imaging technique has a high sensitivity for the early detection of breast cancer with infrequent false-positive results. Because the interpretation of MBI is not affected by breast tissue density, it is an ideal diagnostic complement to mammography.

Medicare and most private insurance companies cover MBI under standard nuclear breast imaging codes.

In May 2007, Weinstein Imaging Associates became the first facility in western Pennsylvania and the entire Pittsburgh tri-state region to offer this service.

 About Dilon Technologies

Dilon Technologies Inc. is bringing innovative new medical imaging products to market. Dilon's cornerstone product, the Dilon 6800, is a high-resolution, compact gamma camera, optimized to perform MBI, a molecular breast imaging procedure which images the metabolic activity of breast lesions through radiotracer uptake. Many leading medical centers around the country are now offering MBI to their patients, including: Cornell University Medical Center, New York; George Washington University Medical Center, Washington, D.C.; and The Rose, Houston.
