Molecular Breast Imaging Performs Better Than Ultrasound in Patients With Mammographic Abnormalities
"My colleagues and I found that in women who needed further examinationbeyond mammography in the diagnosis of breast cancer, BSGI offered moredefinitive answers than ultrasound," said Dr. Jean Weigert, Director ofWomen's Imaging at Mandell and Blau M.D.'s PC, in New Britain, Conn.
Dr. Weigert conducted a study comparing BSGI to ultrasound in patients whorequired additional imaging following a mammogram. As part of their diagnosticevaluation, 70 patients had mammography, ultrasound, BSGI and biopsy. BSGI andultrasound had 96 percent and 58 percent sensitivity respectively and 55percent and 43 percent specificity respectively. These results demonstratethat BSGI may be more useful than ultrasound as an adjunctive imagingtechnology to mammography.
BSGI for the study was conducted using a Dilon 6800 Gamma Camera, ahigh-resolution, small field-of-view gamma camera, optimized to perform BSGI.With BSGI, the patient receives a pharmaceutical tracing agent that isabsorbed by all the cells in the body. Due to their increased rate ofmetabolic activity, cancerous cells in the breast absorb a greater amount ofthe tracing agent than the normal surrounding tissue and generally appear as"hot spots" on the BSGI image.
Dr. Weigert concluded that, "BSGI provided superior sensitivity andcomparable -- if not better -- specificity in this group of patients withquestionable mammograms requiring additional diagnostic imaging. BSGI may be amore useful modality than ultrasound as an adjunct imaging technology tomammography."
