Magnetic resonance imaging has since its beginnings until today evolved into one of the most important methods of diagnosis of the brain disesases. Since the introduction in the clinical application, magnetic resonance imaging has shown as the most sensitive method of early presentation of intracranial pathology. At the same time the MRI is a method of choice in the diagnosis of diseases of the white matter of the brain and pituitary gland, hearing disorders, especially in defining the focal epilepsy. The basic principle of MRI is based on the behavior of atomic nuclei of certain chemical elements that make up the object of MRI time, a strong magnetic field. These behaviors is possible to obtain cross layers of bodies with specific display pathological anatomical structures. PURPOSE: A retrospective analysis show the importance of the application of intravenous paramagnetic contrast agent in MRI. METHODS:We analyzed 25 are randomly selected patients (9 men and 16 women aged 7-78 years) where in the Department of Diagnostic and InterventionalRadiology, Clinical Hospital Split in the period from 1 January 2015 to 1 October 2015. Magnetic resonance imaging of the brain was made with application of intravenous contrast Dotare 0.5 mm / ml on suspicion of the existence of pathological processes in the brain. Magnetic resonance imaging is made to Avanto 1.5T MRI device company Siemens. Scanning is made in supination with all accessories and necessary intravenous contrast 0.2 ml / kg body weight. CONCLUSION:The use of paramagnetic contrast agent canbe a great show anatomy pathologic lesions in the brain. The use of intravenous contrast, it is justified to some part of the protocol of magnetic cloud.
