New Imaging Technique Better at Detecting Breast Cancers

New Imaging Techniques Better at Detecting Breast CancersHaving Fibrocystic Breast Disease for years has produced dense breast tissue with age for me. My annual mammogram usually goes into an added ultrasound in order to visualize densities with greater definition. Now the Mayo Clinic has developed a new breast imaging technique that can detect breast cancers with much greater accuracy.

Breast Imaging ultrasound

From an article in today’s Science Daily:

“Molecular Breast Imaging (MBI) is a supplemental imaging technology designed to find tumors that would otherwise be obscured by surrounding dense breast tissue on a mammogram. Tumors and dense breast tissue can both appear white on a mammogram, making tumors indistinguishable from background tissue in women with dense breasts. About half of all screening-aged women have dense breast tissue, according to Deborah Rhodes, M.D., a Mayo Clinic Breast Clinic physician and the senior author of this study.

MBI increased the detection rate of invasive breast cancers by more than 360 percent when used in addition to regular screening mammography, according to the study. MBI uses small, semiconductor-based gamma cameras to image the breast following injection of a radiotracer that tumors absorb avidly. Unlike conventional breast imaging techniques, such as mammography and ultrasound, MBI exploits the different behavior of tumors relative to background tissue, producing a functional image of the breast that can detect tumors not seen on mammography.”

Michael O’Connor, Ph.D., a Mayo Clinic scientist and inventor of the MBI technology, calls this latest study a major milestone for both safety and efficacy of the imaging device, largely because of the high detection rates achieved through low radiation exposure…This means MBI is safe and effective as a supplemental screening tool… (and) fills an important gap for supplemental screening in women with dense breasts who are not otherwise at high risk.

 Wonderful news for all of us dense breasted women, which means better accuracy in detection and diagnosing, and less exposure to radiation year after year. Congratulations Mayo Clinic!
