In 22 premature children (12 normal prematures and 10 with brain pathology) echodensity was measured as average grey scale values. For performing the measurements, echoencephalograms were recorded on videotape and analysed by an IBM-AT computer and a high resolution framegrabber. An evident difference of echodensity was measured between normal parenchyma, skull, fresh cerebral haemorrhages and cerebral oedema.
