More than ten BSGI/MBI educational exhibits will be presented at the 2010 Radiological Society of North America ( RSNA-2010 ) annual meeting in Chicago.

Breast-Specific Gamma Imaging/Molecular Breast Imaging (BSGI/MBI) is gaining momentum as a standard of care in the diagnostic work up of patients. More than ten BSGI/MBI educational exhibits will be presented at the 2010 Radiological Society of North America ( RSNA-2010 ) annual meeting in Chicago next week. These upcoming presentations, along with others at radiology, surgical and breast disease medical society meetings all around the world, continue to demonstrate the viability of the technology as an important diagnostic tool for early breast cancer detection. In addition, the Society of Nuclear Medicine (SNM) recently released a nuclear medicine breast imaging protocol that includes specific procedural guidelines and clinical indications for conducting BSGI/MBI.

BSGI/MBI is especially useful in difficult-to-diagnose cases such as Ductal Carcinoma in Situ (DCIS), where mammography may not accurately display the extent of the disease, as demonstrated by one of the RSNA exhibits by researchers from the George Washington University Medical Center in Washington, D.C. The authors used BSGI/MBI to detect DCIS lesions (ranging from 1 mm to several centimeters), to determine the extent of disease and varying pathological parameters. At the RSNA they will demonstrate the sensitivity of BSGI for DCIS to be 93 percent to 95 percent. "BSGI is a valuable tool that improves diagnostic accuracy, and complements other modalities, when included in the breast imaging protocol," said Jocelyn A. Rapelyea, MD, associate professor of radiology, George Washington University. "This modality is especially effective in assessing the extent of disease and assisting in surgical planning."

Another study that will be presented at the RSNA by investigators from Weinstein Imaging in Pittsburgh compares BSGI to mammography and ultrasound in patients undergoing diagnostic evaluation. The investigators demonstrate that BSGI is a useful tool for improving the detection of malignancies and note that the physiological information of BSGI is complementary to the anatomical depiction of the breast by mammography and ultrasound .
