Experience with contrast mammography in the diagnosis of various breast diseases.

Contrast mammography, with oxygen or positive contrast material, was performed on 88 women with various diseases of the breast. The examination was done after simple mammography had failed to establish a clear diagnosis. In each case, the roentgenologic diagnosis was confirmed by histological examination. In some cases, bicontrast studies of the duct system or of cysts were performed. With contrast mammography, a correct diagnosis was established in 98.7% of malignant tumors and in 97.8% of benign tumors. Bicontrast studies demonstrated intraductal and intracystic malignancies.
