Computer Assisted Axial Tomography in Cerebrovascular Lesions

Abstract

Computer assisted axial tomography was performed in 32 patients with clinically possible cerebrovascular lesions. Decreased absorption as a sign of infarction was found in 15, increased absorption as a sign of hemorrhage in 7 cases. In another 7 cases, diagnosed as hemorrhagic infarction, a simultaneous occurrence of increased and decreased absorption appeared. Increased absorption might also depend on compression effect of edema. In three cases no abnormal attenuation could be demonstrated. Infarctions could be observed years after the onset of the symptoms; intracerebral hemorrhages regressed slowly.

The role of computed tomography in evaluation of the acute ischemic stroke

“…The central place in diagnosis and management of acute ischemic stroke (AIS) to date, has non-contrast computed tomography (NCCT) (9,19). At the beginning, CT was used for brain imaging and thus, it found place in cerebrovascular diagnostics (20)(21)(22). Its use is widespread and also short scan time, noninvasiveness and safety, make it the first-line in imaging of acute ischemic stroke (9,10).…”

Differentialdiagnose des Schlaganfalles im Computer-Tomogramm

“…Grumme, S. Lange, W. Meese Findet sich eine Kombination von unscharf begrenzten Zonen verminderter und vermehrter Dichte (Abb. 3 a), so muß eine Durchblutungsstörung mit hämorrhagischer Infarcierung angenommen werden (7,28).…”

“…Die axiale Computer-Tomographie erlaubt in vielen Fällen eine exakte differentialdiagnostische Aufhellung der zum Schlaganfall führenden Faktoren (2, 4, 7,8,12,16,17,19,22,23,26). Teilverschlüsse im Bereich der Arteria cerebri media.…”

Prognostic significance of cerebral computed tomography results in supratentorial infarction

“…Computed tomography (CT) in cerebrovascular lesions allows the differentiation between cerebral infarction and recent haemorrhage with a high degree of precision, as well as assessment of the location, extent and topographic relations of a lesion ( Ambrose 1973, Scott et al 1974, Cronqvist et al 1975, Lukin et al 1977.…”
