Clinical application and progresses of contrast-enhanced spectral mammography / 中国医学影像技术

ABSTRACT

Breast cancer is the most common cancer in female population. Early detection of breast lesions and proper differentiation will directly impact on clinical treatment strategy and is related with prognosis. Breast tumors are usually rich in vascularity. Contrast-enhanced spectral mammography (CESM), based on K-edge effect of iodine, can acquire images of iodine contrast distribution in breasts through special computing and subtraction of images with both low- and high-energy X-ray exposures after intravenous induction of iodinated contrast media. It can eliminate the disturbance caused by overlapping breast tissues and demonstrate blood supply of the lesions, thus is sensitive to small lesion, more accurate in tumor delineating and able to help diagnosing. The current clinical applications and progresses of CESM were reviewed in this article.
