Magnetic resonance imaging (MRI), magnetic resonance tomography (MRT), is an imaging technique that provides informative images of internal body structure. One of the main technology benefits is the option to manipulate image contrasts. By manipulating the time tissue is given to relax one can make use of the relaxation time disparity to extract images with distinct contrasts. The image is called weighted depending on the most distinctly appearing effect. Three common types of images are: T1, -T2- and proton-weighted images. Proton density of the body along with tissue relaxation times are thus properties that determine how tissue appears in an MRI image. This thesis will examine how the protocols concerning T1- and T2- relaxation are designed in MRI examinations of neonatal children and other newborn babies up to 3 months of age. With the purpose of this in mind, the following question was formulated: How is the T1- and T2- values effected on a non-fully developed brain? In order to achieve the purpose of the thesis a qualitative approach has been conducted and the research is based on studies of articles concerning neonatal children and MRI. The study concludes that T2- relaxation values increase in neonatal children and other newborn babies up to three months of age but is consistently changing with the child´s continuously growth while T1- values appear to differ very little between children and adults.
