MR-visualization of volume formation of the dog's brain

The purpose of the study was to determine the algorithm and explore the possibilities of magnetic resonance imaging (MRI) in the diagnosis of volume formation of the dog's brain. The tasks of the study included the determination of the size, localization and boundaries of the changes in the dog's brain. The object of the study was the dog of Rottweiler breed, aged 7 years, treated in the veterinary clinic "Mukhtar". The owners of the animal complained of the distortion of mental status, disorientation and the loss of habitual actions of the dog over the past six months. The dog's brain was examined using a radio frequency receiving coil with a surface matrix (Head). The examination on an Mr-tomograph with magnetic field’s strength of 1.0 Tesla was started with a quick reconstruction of the images of the search program (Localizer or Scout) and approximate slices of the animal's brain in the sagittal, transversal and frontal planes were obtained. According to the results of the diagnostics, the following results were obtained: in the right frontal lobe, cystic solid volume formation with indistinct uneven contours, of rounded shape, with approximate dimensions of 1.7×5.1×6.6 cm, as well as a non-uniform ISO-hypointensive signal on T1 and ISO-hyperintensive signal on T2 of weighted image (VI), with the case of perifocal edema of the brain substance was determined. The formation shifted the median structures from the right to the left up to 0.3 cm. Properly formed structures, such as the cortex, white matter, furrows and the brain convolutions, basal structures and the brain stem had normal magnetic resonance strength, the division into gray and white matter of the brain was satisfactory. After analyzing the data obtained, one can safely say that MRI is undoubtedly the best method for diagnosing brain tumors, and it can also be used for screening dynamic control. An algorithm for evaluating and predicting the effectiveness of diagnostics, as well as correct treatment tactics can increase overall survival and ensure satisfactory quality of life for animals.
