CHICAGO, Dec. 1 Breast-Specific Gamma Imaging (BSGI), amolecular breast imaging technique that is substantially less expensive thanbreast magnetic resonance imaging (MRI) with comparable sensitivity fordetecting breast carcinoma when used in presurgical planning for patients withknown cancer diagnoses, according to findings presented today at the annualmeeting of the Radiological Society of North America (RSNA).
"According to the national Medicare average, BSGI costs $219.43 comparedto $994.43 for breast MRI. Since BSGI has some advantages over MRI, includinghigher patient tolerance and significant cost savings, BSGI should beconsidered an alternative for preoperative planning in patients with breastcarcinoma," said Dr. Margaret Bertrand, Director of Breast Imaging at SolisBertrand Breast Center in Greensboro, N.C.
In this study, BSGI was performed prior to needle biopsy on 63 patientswith 64 breast malignancies who subsequently had a post-biopsy, preoperativebreast MRI for surgical planning in accordance with the ACS guidelines. Of the64 malignancies, BSGI and MRI were positive in 61 and 62 lesions,respectively. BSGI and MRI were comparable in sensitivity for breastcarcinoma, 95 percent and 97 percent respectively. Unlike MRI, BSGI wastolerated by all patients.
BSGI for the study was conducted using a Dilon 6800 Gamma Camera, ahigh-resolution, small field-of-view gamma camera, optimized to perform BSGI.BSGI is a molecular breast imaging technique that can see lesions independentof tissue density and discover very early stage cancers. With BSGI, thepatient receives a pharmaceutical tracing agent that is absorbed by all thecells in the body. Due to their increased rate of metabolic activity,cancerous cells in the breast absorb a greater amount of the tracing agentthan the normal surrounding tissue and generally appear as "hot spots" on theBSGI image.
