[Localisation of mammographic findings, suspect of malignancy but not palpable, and their histologic patterns].

A technique of marking non-palpable changes in mammograms for the surgeon is described. The suspected area is injected with contrast medium and patent blue. The radiologist can assess the exact site and the surgeon can recognize it at operation. Radiographs of the specimen removed can make sure whether the suspect area was removed. There were 13 preclinical cancers, 2 cancers in site, 1 sclerosing adenosis, 1 proliferating mastopathy, and 66 fibrous or fibrocytic mastopathies. Among contrast media Urografin 76% appears the best because of its sufficient contrast density and complete reabsorbtion. So far there have been no serious complications
