On the base of analysis of 5784 events of diagnostic magnetic-resonance tomography studies of the head of patients in radio diagnosis departments the database is formed. Only events (n=411) without cerebral, oncology, endocrine and other pathology are taken in database. The material was grouped to time and date of the study, sex and Age in accordance with generally accepted categorization. Maximum linear sizes of pineal gland and hypophysis cerebri in sagittal, axial and coronar projection were measured in all events; volumes of the organs were calculated on the formula of a ball. It is defined that the volume of pineal gland increases from birth till 17-21 year age, gradually falls till the second mature age and is getting stable in old age. The normative factors of the volume of pineal gland and hypophysis cerebri for 8 age groups are determined. "Brain sand" and false cysts in pineal gland can be observed in all age groups. The petrification degree of pineal gland, as of computer tomography, varies from 30 to 277 ed. HV. For the factor of pineal gland volume and factor of cysts frequency in pineal gland a puberty "collapse" is typical, mainly in men.
