Molecular Breast Imaging Has Greater Sensitivity Over Mammography, Ultrasound and MRI for Invasive Lobular Carcinoma
"Our study compares the sensitivity of mammography, ultrasound, MRI andBSGI in the detection of ILC. We found BSGI to have the greatest sensitivityof all four techniques," said Dr. Rachel Brem, Director of Breast Imaging andIntervention at George Washington University Medical Center in Washington,D.C., and Vice Chair of the Department of Radiology.
This study was a retrospective multi-center study of women withbiopsy-proven pure ILC. Patients had imaging performed with mammography andBSGI. Ultrasound and MRI results, if performed, and pathologic tumor size wereincluded for analysis. The sensitivity of mammography, ultrasound, MRI andBSGI was determined for each modality and compared. Twenty-six women, ages 46to 82 (mean age of 62.8), with 28 biopsy proven pure ILC, mean size of 22.3mm(2mm -90mm) were included.
BSGI had the greatest sensitivity for the detection of ILC with asensitivity of 93 percent. Mammography, ultrasound and MRI demonstratedsensitivities of 79 percent, 68 percent and 83 percent, respectively.
The 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. Brem has published many articles on breast cancer-related topics inher areas of interest, which include new technologies for the early diagnosisof breast cancer and BSGI.
"BSGI is an effective adjunct imaging modality for the diagnosis of breastcancer and has a promising role in the diagnosis of ILC," said Dr. Brem.
