[Magnetic resonance imaging in the diagnosis of renal neoplasms : MRI - histopathological comparison].
The study evaluates the diagnostic of the MRI in the discovery and characterizing renal neoplasms. The principle of the comparative study of MRI, other diagnostic modalities and histopathological data was applied by the author, using a large pool statistically significant clinical material (419 cases). Renal cell carcinoma--the most wide-spread renal parenchyma's tumor, was selected as a morphological model (302 cases). As a result of this investigation, the MRI semiotics of renal cell carcinoma was more precisely defined and detailed and this method's high level of sensitivity (98.4%) was detected, concerning the detection of such a type of pathology. The MRI data reliably reflect (r > 0.8; P < 0.05) the true morphological structure of the tumor's growth, the secondary tumor's tissue alterations and its interaction with surrounding anatomical formations. Thus, MRI is appreciated as a method of choice for oncological urology.
