The authors report about their preliminary experience with MRI in the diagnosis of breast disease. 50 breast masses in 41 consecutive patients have been evaluated by MRI and mammography, some of which have been evaluated by ultrasound, as well. All masses have consequently been biopsied. They include 32 carcinomas, 1 secondary malignant lymphoma, 4 fibroadenomas, 2 papillomas, 3 cysts, 1 hamartoma and 5 dysplastic nodules. Advantages and disadvantages of MRI of the breast are discussed. Possible future indications are suggested for selected cases.
In spinal lesions GD-DTPA has led to a better diagnosis of tumors concerning the extent and differential diagnosis. Important indications for the application of GD-DTPA are intramedullary tumors: excellent information with respect to extent and differentiation cyst from tumor. At extramedullary intradural tumors we got distinction of extramedullary from intramedullary tumors and more information in the differential diagnosis for example in cases of neurinomas and meningiomas. Additional information is also obtained by means of GD-DTPA in extradural tumors: better delineation from the myelon, better possibilities to differentiate between meningiomas, neurinomas and scar and tumor.
In several institutions lumpectomy combined with radiation treatment is being investigated as an alternative method in the primary management of breast cancer (1-5). In 8 of 53 patients, who had undergone this treatment, new calcifications developed after therapy. In 2 of the 53 patients postoperatively persisting calcifications were encountered. The authors report about their preliminary experience in the diagnosis of calcifications after this therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
