The article deals with the problem of introducing methods for the evaluation of MRI based on the values normalized by the Hounsfield scale in the radiologist's activity. The model allows to normalize the intensity of MRI. Various settings for temporary capture in the tomograph and correlation of the normalized values of the themes with the values of the Hounsfield scale. This model allows to extract additional diagnostic function from MRI data, as well as to reduce the amount of CT and related costs. Conceptual and algorithmic models are presented.
