We reported the correlation between the angio-graphical findings and parameters of the functional im-ages of dynamic CT (FID-CT) in ten patients with cerebral ischemic disease. Six of these ten patients with an abnormal area on corrected mean transit time (CM) and time to peak (TP) had complete occlusion of in-tracerebral main arteries with poor collateral cerebral blood flow or no collateral flow on the angiography. Four patients with prolonged time only in the TP area, but not in the CM area, had stenosis or occlusion of the main trunk with satisfactory anterograde cerebral blood flow on the angiography. FID-CT is easy to apply for clinical use and said to be useful to predict arterial trunk occlusion or infarction volume. It might also be helpful to get further information about the intracere-bral circulation disorders in the acute stage of cerebral ischemic disease.
