Gray-scale echography for breast cancer.

Gray-scale echography offers considerable potential as a diagnostic modality for the visualization of pathological processes in breast diseases such as carcinoma, benign cyst, fibroadenoma, mastopathy and others and is complementary to conventional techniques. Differential diagnosis of breast tumors was carried out based upon the echographic findings such as the boundary echo and shape, internal echo, and retromammary or retrotumorous shadowing. Typical echographic displays for the differential diagnosis of breast tumors from other breast lesions are presented and discussed.
