title: [Intracranial cysts of different etiologies--the correlations between data from ultralow-field magnetic resonance tomography and results from biochemical analysis].
abstract: The paper presents the results of comprehensive examination of 7 patients with intracranial cysts of various etiology and 1 with cholesteatoma. In addition to magnetic resonance imaging with an ultralow magnetic field intensity of 0.4 T, a biochemical assessment of the content of cysts was made. The cystic contrast range on T1 and T2 tomograms was evaluated. The levels of protein, total iron, and percentage of total solids of the cystic content were measured in the biochemical study. On T2 tomographs, the intensity of a signal from cysts on T2 tomographs was significant and differed in each case to a lesser extent. On T1 tomographs, the intensity of a signal was different in each case and increased virtually linearly as the concentration of protein increased up to 10%. The presence of paramagnetic active iron ions (reduced hemoglobin) in the cysts resulted in a much greater elevation of a signal on T1 tomograms. The findings are given as plots that associate the relative intensity of a signal with the concentration of protein. The total solids in the cysts examined predominantly showed protein.
