[Indications for various interventional radiology techniques in the diagnosis of suspicious breast lesions]

Interventional imaging permits the logical management of possibly malignant abnormalities, on condition that good guidance techniques and good sampling tools appropriate to the target image are available. Aspiration is a simple and effective technique well suited to abnormalities detected after screening and unlikely to be malignant. Microbiopsy of possibly nodular abnormalities makes it possible to confirm the diagnosis and to improve management strategy. Biopsy by an image-guided minimally invasive aspiration device is an essential tool for management of microcalcifications because it can avoid nearly half of the surgical interventions for benign lesions. For malignancies, it improves the rate of useful surgical biopsy and facilitates an appropriate surgical strategy. Ultrasound-guided biopsy should become increasingly important in breast care, but its indications must be carefully defined.
