Elastography Reduces Unnecessary Breast Biopsies
Date:11/29/2009

on biopsy, and 82 percent of lesions that turned out to be benign. Elastography was also more accurate than ultrasound in gauging the size of the lesions.

"Ultrasound can underestimate the true size of lesions, as it only sees the actual mass and not the surrounding changes the mass may cause," Dr. Destounis said.

In 2009, there will be an estimated 192,370 new cases of invasive breast cancer among women in the United States, according to the American Cancer Society, along with about 62,280 new cases of ductal carcinoma in situ, a noninvasive, early form of breast cancer.

Coauthors are Andrea L. Arieno, B.S., Melissa N. Skolny, M.S., Renee Morgan, R.T., Patricia Somerville, M.D., and Philip F. Murphy, M.D.

Also at RSNA 2009, Dr. Smitha Putturaya, M.D., F.R.C.R., presented findings from an ongoing, seven-year study on breast elastography conducted at the Charing Cross Hospital Breast Unit in London, U.K. Dr. Putturaya and colleagues found that using elastography as an adjunct to routine breast ultrasound safely decreases the number of biopsies of benign lesions and offers the potential to map tumors more precisely.
