Perfusion CT
The CBF image shows a severe perfusion disturbance
(flow close to zero) in the insular cortex and the poste-
rior portion of the lentiform nucleus. In comparison to
the left hemisphere the remaining supply area of the
middle cerebral artery shows moderately reduced flow.
• The CBV image shows the same severe reduction in
insular cortex and lentiform nucleus. In contrast to
the CBF image, however, the blood volume in the
remaining right MCA territory is close to normal, if it
is compared to the same area on the left side.
• The time-to-peak image shows a general prolonga-
tion of values in the MCA territory indicating delayed
bolus arrival.
