Voir les microcalcifications mammaires en échographie: luxe ou nécessite ?

Ultrasound is unsuited for the diagnosis of microcalcifications because it fails to visualize a mass in one-third of cancers and the existence of a mass is correlated with malignancy in one-third of cases. Furthermore, US does not correct the false-negative errors of mammography, and it underestimates the rate of malignancy by ascribing a benign appearance to 50% of cancers, which mammography correctly classifies BI-RADS 4 or 5.
