BSGI Posts Higher Sensitivity than Mammography or MRI for the Detection of Ductal Carcino...( NEWPORT NEWS Va. Aug. 10 /- Study...),Health

NEWPORT NEWS, Va., Aug. 10 /PRNewswire/ -- Study results recently published in the Journal of Academic Radiology indicate that Breast-Specific Gamma Imaging (BSGI) provides higher sensitivity for the detection of Ductal Carcinoma In Situ (DCIS) than mammography or MRI and can reliably detect small, sub centimeter lesions. The study, performed by Dr. Rachel Brem and colleagues at The George Washington University Medical Center, evaluated the procedure on women with mammographically suspicious microcalicifications and other high risk factors.

According to Dr. Brem, Breast Specific Gamma Imaging (BSGI) -- nuclear medicine imaging of the breast utilizing a high-resolution gamma camera -- is an increasingly utilized adjunct imaging modality for the diagnosis of breast cancer. Many recent studies and clinical work around the country on over 20,000 patients have demonstrated the significant value of BSGI as a complement to mammography in detecting breast cancer.

The Brem study demonstrated the efficacy of BSGI in helping to find otherwise mammographically occult cancers and in determining the true extent of disease in order to optimize surgical planning. BSGI accurately detected all four DCIS less than or equal to 5 mm (100 percent) and all six DCIS less than or equal to 10 mm (100 percent) with measurable residual disease at surgical excision. Overall, BSGI demonstrated 91 percent sensitivity for DCIS, specifically detected low-grade DCIS and identified several lesions not found on mammography or MRI. The smallest lesion noted was 2 mm.

"We believe this is an important contribution to the literature in that it compares different imaging modalities for the diagnosis of DCIS, a timely issue," said Dr. Brem.

DCIS

Ductal Carcinoma In Situ (DCIS), the most common type of non-invasive breast cancer, occurs in approximately 28 percent or over 58,000 cases of breast cancer in the U.S. Mammography, the only accepted screening tool for breast ca
