New Gamma Camera Technique For The Detection Of Small Breast Tumors

A diagnostic device that resembles a mammography unit can detect breast tumors as tiny as one-fifth of an inch in diameter, which may make it a valuable complementary imaging technique to mammography, say researchers at Mayo Clinic, who helped develop the technology along with industry collaborators Gamma Medica and GE Healthcare.This new technique, Molecular Breast Imaging, uses a new dual-head gamma camera system and is sensitive enough to detect tumors less than 10 millimeters (about two-fifths of an inch) in diameter in 88 percent of cases where it is used. Early findings from an ongoing comparison of the device with mammography show that it can detect small cancers that were not found with mammography, say the investigators. Mayo Clinic physicist Michael O’Connor, Ph.D., will present these results Saturday, Dec. 16, at the 2006 meeting of the San Antonio Breast Cancer Symposium.“Our ultimate goal is to detect small cancers that may be inconspicuous or invisible on a mammogram for high-risk women with dense breasts,” says Dr. O’Connor. --Click the title of this post to read the full article from its source--
