CT and angiography in cases with occlusive disease of supratentorial cerebral vessels.

A correlation between CT and angiography in patients with occlusive diseases of cerebral vessels in the supratentorial area was made. This study confirms the poor diagnostic value of CT in patients with TIA. In patients with completed stroke CT was very often positive (85%), as well as the angiography. Nevertheless good correlation between these two examinations was found only in 40% of the patients. With CT alone, it is often not possible to predict which vessel is primarly involved. For precise diagnosis angiography must follow.
