both patient and cost effective.

NEWPORT NEWS, Va., March 6 /PRNewswire/ -- A recent study performed by Dr. Margaret Bertrand, Director of Breast Imaging at Solis Bertrand Breast Center in Greensboro, North Carolina demonstrated the significant value of Breast-Specific Gamma Imaging (BSGI) as an adjunctive procedure in breast diagnostics; specifically demonstrating BSGI to be a useful and cost effective procedure in the breast diagnostic work up. The study results were recently presented at the Miami Breast Cancer Conference.

Breast-Specific Gamma Imaging is a molecular breast imaging technique used for the early detection of breast cancer and in the differentiation of malignant and benign tumors. It relies on advanced gamma imaging technology and mammographic positioning to optimize results. For this study BSGI was conducted with a commercially available high-resolution gamma camera, the Dilon 6800.

Dr. Bertrand's study evaluated the clinical impact of BSGI as an adjunctive imaging modality in a comparative analysis with other imaging methods; using tissue biopsy as the gold standard. The facility conducted diagnostic workup, including BSGI, on 98 lesions consisting of 69 malignancies.

Because imaging was prescribed as necessary, not all modalities were employed for each case. Since all patients had both mammography and BSGI, these were established as the constants with US and MRI as variables. Seventy-five percent (64/75) of the lesions detected when BSGI was compared to MRI had concordant BSGI and MRI findings with 11 discrepancies. In 74 of the 75 lesions BSGI was conducted pre-biopsy, while MRI was conducted post-biopsy, therefore it is not certain if the MRI findings were positive due to biopsy or disease.

In addition, BSGI was False Negative (FN) in 3 patients and False Positive (FP) in 2, while MRI was FN for 1 patient and F
