Imagerie interventionnelle en pathologie mammaire

The increasing number of nonpalpable breast lesions, detected at screening mammography, has induced the development of percutaneous imaging-guided procedures to reduce the number of diagnostic surgical biopsies. After a description of the indications (classification of the American College of Radiology), the different imaging modalities, the material used and the sampling procedures (ultrasound, mammography with stereotaxy, fine needle aspiration, micro and macrobiopsies and stereotactic surgery) will be described. Results of the different percutaneous procedures will be discussed. Clear information to the patients, efficient quality control and multidisciplinary approach are mandatory for the success of these percutaneous diagnostic procedures. Localization techniques before surgery will be presented.
