Contrast-enhanced spectral mammography (CESM) is a new technology that is designed to generate contrast-enhanced images of the breast using an approved X-ray contrast agent and a dual-energy acquisition technique.

GE Healthcare (Chalfont St. Giles, UK), a unit of General Electric Company (Fairfield, CT, USA), announced US Food and Drug Administration (FDA) 510(k) clearance of the innovative technology to aid the physician in breast cancer diagnosis. GE estimates that by 2020, more than one million women worldwide will be examined using SenoBright CESM, and this technology can help lead to more productive diagnosis paths for nearly 250,000 women.

Launched in 2010, SenoBright is already in use at 17 major mammography centers in France, Spain, Italy, Belgium, Germany, Austria, and Japan. SenoBright uses X-rays at multiple energies to create two separate but almost simultaneous exposures. The resulting images specifically illuminate and highlight areas of iodinated contrast. “CESM presents two images per mammographic view, one that looks like standard mammography and a second image that showed the contrast enhanced areas that can help localize a lesion. As the images are familiar, it can therefore be easily reviewed by surgeons and oncologists. Moreover in terms of workflow, a CESM exam takes from 5 to 10 minutes,” said Dr. Clarisse Dromain, Gustave Roussy Cancer Institute (Villejuif, France).

“Worldwide, more than 1.2 million people annually are diagnosed with breast cancer. Since 1965, GE Healthcare has made significant progress in providing solutions for breast cancer detection and diagnosis that really bring a change to people’s lives. Today through ‘healthymagination,’ we continuously develop innovations to reduce costs, increase access and improve quality and efficiency of healthcare delivery around the globe,” said Anne LeGrand, GE Healthcare’s vice president and general manager of the company’s global X-ray business.

Digital mammography is considered an important means of breast cancer screening, delivering proven clinical outcomes. The sensitivity and specificity of images can, however, be affected by a range of factors. Dense breast tissue can overlap with lesions, which are not always visible on an X-ray, and radiologists’ interpretation of images can vary. Inconclusive digital mammography presents a range of challenges to healthcare professionals and patients. Ambiguity can result in diagnostic error.

SenoBright is intended to allow for a procedure to be conducted by the same staff, using the same mammography equipment, potentially on the same day as a traditional screening exam, thereby helping medical professionals to cut the critical time patients often have to wait from detection to diagnosis. GE Healthcare estimates that 2500 digital mammography systems upgradeable to SenoBright are in clinical use today. “Given our proven history of breast imaging innovations, GE is proud to showcase another innovative technology, designed to be compatible with our digital installed base. We are one of the only companies today to engineer and manufacture the entire mammography imaging chain from tube, and detector to review workstation, coupled with integration of the comprehensive local requirements for each customer,” added Ms. LeGrand.

CESM technology is intended to work as an upgrade to GE Healthcare’s Senographe DS and Senographe Essential digital mammography equipment. GE’s Senographe platforms are full-field digital mammography systems designed to meet a wide range of clinical needs, from screening to diagnostic and interventional procedures.
