[Tumor differentiation by multivariate discriminant procedures in CT absorption analyses].

An attempt is made to utilise so-called absorption analyses in cranial CT for further differentiation of the diagnosis of the various types of space-occupying growths. Characteristic distributions are shown for specific "regions of interest" in meningiomas, glioblastomas and cerebral abscesses before and after contrast medium injections. Clear criteria can be formulated for the differentiation of glioblastoma and cerebral abscess using multivariate discriminance analyses.
