Perfusion CT correlating with DSA. CT perfusion with MTT (sec) (a), TTP (sec) (b), CBF (mL/100 g/min) (c), and CBV (mL/100 g) (d) showing circumscribed perfusion deficit on the territory of the left MCA. No evidence of infarction as shown on native CT scan (f). Digital subtraction angiography (e, g) of the left ICA from the same patient on the same day showing vasospasm of the left ICA above the ophthalmic artery of the median and anterior cerebral artery.
