[MRI features of space-occupying lesions in the breast]

Our study evaluates the correlation between benign and malignant breast masses contrast enhancement, on the one hand, and the type of the vascular net and histological prognosis, on the other. We reviewed the preoperative images of 298 breast masses (benign--95 (32%), malignant--203 (68%)) after dynamic contrast enhancement as well as on the basis of pathomorphological data. Due to use of high-concentration paramagnetic contrast agents in ultra-fast sequences, benign and malignant tumors could be differentiated. The quantitative data on both intensive contrast and ring-shaped enhancement corresponded to the low capillary density in the center of carcinoma which correlated with poor prognosis.
