NEW YORK (MedscapeWire) May 01 Four studies presented April 29-30 at the American Roentgen Ray Society annual meeting in Atlanta, Georgia, illuminate the future of breast cancer screening. Infrared light, radar, ultrasound, and even second opinion on mammogram readings may all brighten the outlook for breast cancer detection.
A hand-held device using infrared light for diffuse optical tomography can assess breast metabolism and blood volume to help determine if a mass is malignant. The device weighs less than 2 pounds, is portable, and can be connected to a laptop computer. Testing takes about 10 minutes.
"This might ultimately prove to be an ideal way to image women who wouldn't otherwise have access to high-tech breast examinations," lead author S. Adusumilli, MD, from the University of Pennsylvania in Philadelphia, says in a news release. She notes that the technique involves no radiation, breast compression, or contrast injection. In 32 patients with an abnormal mammogram or a palpable breast mass, testing showed increased blood volume and deoxygenated hemoglobin in most who had biopsy-proven cancer.
