[Interventional echography in senology].

The echographic investigation in senology represents a complement to the mammography in the early diagnosis of carcinoma, above all when it is still expressed through radiological indirect signs (glandular distortion and microcalcifications) in absence of a nodule. The echographic examination must be done with probes suitable to the superficial tissue: 7.5-10 MHz color and power Doppler. This examination has a greater significance in the identification of the benign lesions, in the control of the operated breast and in the guide of the interventional manoeuvres (FNAB, mammotome, core biopsy, preoperative localization of not palpable nodules).
