[Cisternography via computerised tomography: technique and pathophysiology as causes of the side effects (author's transl)].

The article reports on experiences collected with intrathecal contrast amplification in computerised tomography, using the nonionic contrast media metrizamide and iopamidol in a total of 80 examinations. The side effects are caused by the examination technique - which is discussed in detail -, the pathophysiology of CSF dynamics and the pharmacodynamics of the contrast media, but such side effects can be kept low if the relevant principles are observed. This makes the method both feasible and valuable.
