Early Ischaemic Changes

Other early ischaemic changes

Other changes on CT which are suggestive of an early ischaemic stroke include: loss of grey-white matter differentiation , cortical sulcal effacement , loss of the insular cortex  (“insular ribbon” sign) and decreased density of the basal ganglia  (“disappearing basal ganglia” sign) (Figures 1 and 2). These signs could be appreciated if the abnormal left side was compared to the right hand side.
