In a preliminary study 20 patients underwent breast examinations by magnetic resonance (MR) imaging without and with Gd-DTPA as contrast medium. All carcinomas enhanced, whereas dysplastic tissue enhanced slightly or not at all. Significant additional diagnostic information was available on the Gd-DTPA examinations in at least four of 20 cases compared with MR without contrast medium and X-ray mammography. Our preliminary results indicate that MR imaging of breast using Gd-DTPA may be helpful for the evaluation of dense breasts and the differentiation of dysplasia and scar tissue from carcinoma.
