title: [Urgent diagnostic steps in acute manifestation of intraspinal processes].
abstract: Immediate diagnostic clarification is required in patients who develop acute or subacute symptoms suggestive of an intraspinal lesion. In case of symptoms indicating a monoradicular lesion a spinal CT investigation is mostly sufficient. Since polyradicular syndromes are often due to inflammation, examination of the cerebrospinal fluid is the most important diagnostic measure. However, in case of symptoms suggestive of intramedullary lesions, spinal MRT is by far the most effective diagnostic procedure. In patients with symptoms suggestive of a lesion of the cauda equina spinal CT is sufficient in most cases as a first measure, particularly if the lesion can be precisely localized by clinical examination. The decision as to which diagnostic method should be performed first is relevant mainly because of the limited availability of MRT examinations within the daily clinical routine. MRT should thus be used selectively in patients with lesions that cannot be identified by alternative diagnostic methods.
