[Indications for neuroradiological investigations using contrast media in patients with psychiatric disorders (author's transl)].

The results are presented of neuroradiological investigations using contrast media in 100 patients hospitalized in a psychiatric department. The existence of neurological disturbances or the psychoorganic syndrome, as well as the results of screening methods such as EEG and brain scan are important factors in the decision for or against the performance of cerebral angiography or pneumoencephalography. The significance of the "brain atrophy syndrome" accompanying psychotic diseases is discussed. In addition, some cases are demonstrated of organic neurological brain diseases with predominantly psychiatric features, where the diagnosis was reached on the basis of only neuroradiological methods using contrast media.
