title: [Usefulness of functional image of dynamic computed tomography (FID-CT) on acute cerebral ischemic disease: correlation between parameters of dynamic CT and angiographical findings].
abstract: We reported the correlation between the angiographical findings and parameters of the functional images 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 intracerebral 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 intracerebral circulation disorders in the acute stage of cerebral ischemic disease.
