Perfusion data obtained at the level of the lateral ventricles in a patient with a symptomatic 95% stenosis in the left ICA and a 50% stenosis of the contralateral ICA.

A, Preintervention rCBV map.

B, Preintervention TTFM map.

C, Gamma-variate fits corresponding to the depicted regions show a longer TTFM and a smaller rCBV in the symptomatic hemisphere.

D, Postintervention rCBV map.

E, Postintervention TTFM map.

F, Corresponding gamma-variate fits. Note the resolution of interhemispheric asymmetry in TTFM.
