Imagerie dans le cancer du sein

Imaging of breast cancer is multimodal. Mammography uses X-rays, the development of digital mammography has improved its quality and enabled implementations of new technologies such astomosynthesis (3D mammography) or contrast-enhanced digital mammography. Ultrasound is added to mammography when there is need to improve detection in high-density breast, to characterize an image, or guide apuncture or biopsy. Breast MRI is the most sensitive imaging modality. It detects a possible tumor angiogenesis by highlighting an early and intense contrast uptake. This method has an excellent negative predictive value, but its lack of specificity (false positives) can be problematic, thus it has to be prescribed according to published standards. An imaging breast screening report must be concluded by the BI-RADS lexicon classification of the ACR and recommendations about monitoring or histological verification.
