Answer

When the breast lesion is visible, ultrasonography is the modality of choice for needle placement (see the following image). This technique provides the advantage of real-time imaging, allowing accurate placement of the needle. Being able to directly visualize the lesion and needle position results in a quicker procedure, reducing the risk of patient morbidity. As in mammographic techniques, the lesion must be transfixed, and orthogonal mammography can be used to confirm that the correct lesion has been localized.

The use of intraoperative ultrasonography by the surgeon in the operating theater, as well as the employment of skin marking, is described in the Imaging and Localization Considerations section, above.
