The paper deals with subject concerning MRI and definition of its capacities in estimation of brain and pituitary condition in athletes. It was performed MRI of 70 persons (43 males and 27 females, aged 18-35) which were divided into 2 groups: the 1st group consisted of 44 athletes and the 2nd – of 26 healthy volunteers. All examined persons in both groups had normal blood indexes results, electrocardiogram, arterial pressure but during the physical stress some of the athletes had transitory arterial hypertension. MRI identified different changes in brain and pituitary (a small hydrocephalus, arachnoidal and unilocular cysts, microadenomas, «Empty cellar syndrome», etc.), more in athletes. It’s shown that MRI gives important information about the condition of brain and pituitary in athletes at the preclinical stage, which may play an important role in addressing issues as training mode, conditions of training, as well as opportunities of selected sports and preventive measures.

Aim. To study the morphofunctional state of the myocardium in young people with diabetes mellitus 1 using magnetic resonance imaging (MRI) technology. Materials and methods. 38 patients (14 men, 24 women), aged 18 to 36 years old, with an experience of type 1 diabetes from 5 to 16 years old were underwent contrastive MRI of the heart. The exclusion criteria were: pronounced electrolyte disorders in the blood, dysproteinemia, chronic liver and kidney failure - glomerular filtration rate (EPI)≤60 ml/min/1.73 m2, thyroid dysfunction, obesity (body mass index ≥30 kg/m2), diagnosed cardiovascular diseases, contraindications for MRI. The indicators of functional changes in the left ventricle (circular strain, strain relaxation index - SRI), peak early diastolic strain (PSRDS) were obtained and the accumulation of the contrast agent in the delayed period were assessed. Results. The obtained results of strain, SRI, PSRDS do not allow to exclude the presence of functional changes in the myocardium of the left ventricle. In 42.11%, zones of accumulation of the contrast agent were visualized in the delayed period (insignificant - 28.95% and moderate accumulation - 13.16%), mainly by the endocardium of the cardiac apparatus (mitral and tricuspid), and in one observation (2.9%) - in combination with unexpressed diffuse heterogeneity of the myocardium of the left ventricle. Conclusion. MRI of the heart is a promising direction in the assessment of early morphofunctional changes in the structure of the myocardium, which will probably make it possible to predict life-threatening changes in the heart muscle in young patients with type 1 diabetes.
