Contrast-Enhanced Breast Tomosynthesis:
It’s that same principle—highlighting what’s most important—behind the introduction of SenoBright, GE Healthcare’s contrast-enhanced spectral mammography (CESM) technology. SenoBright, which received FDA 510(k) clearance in October 2011, produces contrast-enhanced images of the breast using an X-ray contrast agent and a dual-energy acquisition technique.

However, digital mammography offers the option of so-called advanced applications, and two of these, contrast-enhanced mammography and tomosynthesis, are promising candidates for improving the detection of breast lesions otherwise obscured by the summation of dense tissue.
Optimization of contrast-enhanced digital breast tomosynthesis
The Achilles Heel of screening mammography is the detection of cancer in women with radiographic dense breasts. While nearly all cancers will be apparent in fatty breasts, only half will be visible in extremely dense breast . This results, at least in large part, from the masking or camouflaging of noncalcified cancers by surrounding dense tissue. In this chapter, we will discuss several derivative digital technologies being developed to overcome the weakness of conventional mammography (film screen and/or digital mammography). The emphasis will be on digital breast tomosynthesis with secondary discussion of contrast-enhanced digital mammography and combined digital mammographic and ultrasound equipment. It should be emphasized, as of this writing, all the aforementioned technologies are investigational in the United States and none are approved for clinical use by the Food and Drug Administration. The clinical application of these technologies, if any, will be determined by scientific investigation and regulatory approval.
