title: [Ultrasonography investigation of mammary calcifications (author's transl)].
abstract: Ultrasonography recordings in 140 patients with breast cancer, 119 with cystic mastopathy, and 299 with benign mammary tumours showed that calcifications are rarely demonstrated, and that diagnosis is not affected to any degree when they are present. Ultrasonography should be used for examination of the breast following the three traditional clinical, radiological, and cytological investigations. False negatives (7.9% of cancers) and false positives (4.2% of fibro-adenomas) are easily corrected from radiological and cytological findings which are still essential for the diagnosis of most mammary affections. Ultrasonography, however, enables an appreciable reduction in biopsy requests to be made in less than 6% of cases of atypical microcalcification in benign mammary lesions.
