Abstract:
Digital breast tomosynthesis is a 3D radiographic technique that obtains information from a few projection images, these images are the reconstructed into a set of images. Breast tomosynthesis could be used in breast cancer screening and diagnosis. This technique reduced the call-back rate in breast cancer screening, and increased the sensitivity and accuracy in detection of the lesion. Contrast-enhanced dual-energy digital mammography processes low-energy image and subtraction image from high and low energy images, iodine enhancement was performed, which could better depict the enhanced tumor. This technique was only used to diagnosis, it could improve the sensitivity of breast cancer detection compared to the conventional mammography and combined the mammography and ultrasound. Contrast-enhanced dual-energy digital mammography had a higher specificity for detecting index cancer than did enhanced MR imaging, and sensitivity was equal.
