[Value of computerized tomography and magnetic resonance tomography in psychiatric diagnosis].
This paper evaluates the role of computed tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis of psychiatric disorders according to the "International Classification of Diseases" (ICD-10). Indications for CT/MRI can be derived from ICD-10 for the identification or exclusion of defined cerebral lesions resp. for the etiology in organic disorders. Due to the lack of specific morphological findings, CT/MRI do not contribute to the classification of all other diagnoses. CT/ MRI can only exclude causal organic factors. However, ICD-10 provides only few guidelines for ruling out cerebral pathology (e.g. tumors in bulimic anorexia). Therefore, recommendations for routine CT/MRI-investigations for the exclusion of organic disorders are required and might be developed by the quality assurance. Application of CT or MRI: CT plays an important role in diagnostic imaging in routine as well as in emergency situations (haemorraghe, hamatoma, infaction, head injury, tumour, vascular malformation). MRI on the other hand, is more sensitive in the diagnosis of inflammatory diseases, skull base lesions, degenerative changes of the white matter and in the imaging of hydrocephalus and epilepsy.
