  • Title: [Magnetic resonance imaging in the diagnosis of benign renal parenchymal epithelial tumors: MRI -- pathomorphological comparison].
    Author: Dombrovskiĭ VI.
    Journal: Vestn Rentgenol Radiol; 2001; (3):42-50. PubMed ID: 12717934.
    Abstract:
    The study evaluates the MRI diagnostic value in the discovery and characterization of the benign epithelial renal parenchyma's neoplasms. Among more than 700 patients with renal tumors, which underwent MRI, 27 histopathologicaly verified cases of adenoma (10), malignant adenoma (11) and oncocytoma (6) were selected and the retrospective analysis of these 3 groups was performed. The 30 patients with small renal cell carcinoma were accepted as a control group. The benign tumor's MRI semiotics is described in general and in the particular for each nosological form. The author considers that MRI data reliably reflect the true morphological structure of the neoplasm's growth, concerning the secondary tumor's tissue alterations (r = 0.89), the presence (r = 0.92) and safety (r = 0.81) of pseudocapsula. At the same time, the specific MRI criteria for the different types of benign and small malignant tumors were not found.
