Breast-specific gamma imaging identifies hidden breast cancer
EpiVax, Inc., a leader in the field of computational immunology, announced today that it has received a grant from the National Institute of Allergy and Infectious Diseases (NIAID), a division of the National Institutes of Health (NIH), to optimize delivery of an HIV vaccine. NIAID will provide EpiVax with $390,000 over two years for the

Breast-Specific Gamma Imaging (BSGI) is shown to be an effective method of identifying mammographically and clinically occult (hidden) breast cancer.
BSGI is a molecular breast imaging technique that can see lesions independent of tissue density and discover very early stage cancers. According to findings presented today at the annual meeting of the Radiological Society of North America (RSNA) in this study of women where breast cancer was already suspected via mammogram or physical exam, BSGI identified additional suspicious lesions in 29 percent of the patients and found a previously unsuspected cancer in 9 percent of women.
“BSGI is an emerging technology that goes beyond mammography as an effective imaging procedure for early breast cancer detection,” said Dr. Rachel Brem, Director of Breast Imaging and Intervention at George Washington University Medical Center in Washington, D.C., and Vice Chair of the Department of Radiology.
In this study, a retrospective review was performed on the records of all patients who had BSGI examinations over a three-year period. Among these, 159 women who had only one suspicious or cancerous breast lesion on a physical exam and/or mammography, underwent BSGI to evaluate additional cancerous lesions in the breasts, and were proven by pathology to have one or more areas of breast cancer.
BSGI detected an additional suspicious lesion, previously undetectable by mammogram and physical exam, in 46 women (29 percent). BSGI identified clinically and mammographically hidden cancer in 15 of 39 women who had a biopsy or prophylactic excision due to BSGI findings (36 percent) and in 15 women who underwent BSGI in this study (9 percent), including nine women in whom the hidden cancer was present in the same breast as the indicated lesion (6 percent) and six women in whom the undetectable cancer was found in the opposite breast (3 percent).
BSGI for the study was conducted using a Dilon 6800 Gamma Camera, a high- resolution, small field-of-view gamma camera, optimized to perform breast imaging. Dr. Brem and colleagues have published numerous articles on breast cancer-related topics including new technologies for the early diagnosis of breast cancer and BSGI.
Breast-Specific Gamma Imaging (BSGI) has been proven to be a highly sensitive imaging technique for the diagnosis of invasive lobular carcinoma (ILC), a difficult to diagnose breast cancer. BSGI is a molecular breast imaging technique that can see lesions independent of tissue density and discover very early stage cancers. When compared to mammography, ultrasound and

A dual-headed dedicated gamma camera used during molecular breast imaging (MBI) can accurately detect small breast tumors less than 2 cm in size, according to a study performed at the Mayo Clinic in Rochester, MN. One-hundred fifty patients who had suspicious lesions smaller than 2 cm in size were imaged using dual-head molecular breast imaging.

Dilon Technologies, Inc., the leader in molecular breast imaging, announced today that they have formed an alliance with Terason Ultrasound to offer an expanded imaging capability when molecular breast imaging and ultrasound may be required. BSGI is a molecular breast imaging technique that can see lesions independent of tissue density and discover very early stage

A new method of characterizing breast lesions found during an MRI exam could result in fewer biopsies of benign tumors with the benefits of reduced pain and expense for patients and providers, according to a paper that will be presented (Sunday, Nov. 30) at the annual meeting of the Radiological Society of North America (RSNA).

Magnetic resonance imaging (MRI) alternated with mammography at six-month intervals can detect breast cancers not identified by mammography alone, a research team from The University of Texas M. D. Anderson Cancer Center will report at the 31st at the CRTC-AACR San Antonio Breast Cancer Symposium. MRI is known to be more sensitive in detecting breast
