title: [Computer tomographic and scintigraphic aspects of subdural haematomas (author's transl)].
abstract: Cerebral computer tomography in cases of emergency is undoubtedly superior to conventional neuro-radiological methods. The changes during resorption of intracranial bleeds, which are due to their particular physical properties, can supply valuable diagnostic information, but under particular circumstances they may obscure the diagnosis. The diagnosis and differential diagnosis of subdural haematomas may become difficult during the isodense phase. Hyper- and hypo-dense collections of fluid may also be missed unless note is taken of subtile indirect signs and special techniques are used. At the same time, the value of cerebral scintigraphy is emphasised. Valuable information may be expected from early scans (10 to 15 minutes after injection). In this way even shallow, bilateral subdural haematomas can be demomstrated during the acute and sub-acute stage. The degree of uptake depends on the histology of the capsule of the haematoma.
