Apparent diffusion coefficient (ADC) measurements at 6 hours after rt-PA treatment of middle cerebral artery (MCA) clot embolism in the rat. Comparison of animals (means 
SD) with and without additional obstruction of circle of Willis (CW). The threshold of the ADC for the breakdown of energy (77% of control;Olah et al., 2001) is marked by the dotted line. Note the decrease of ADC below this threshold in lateral cortex and striatum of animals with combined MCA/CW occlusion but not in the medial cortex or in any region after selective MCA occlusion. These measurements underline the predictive power of magnetic resonance angiography for treatment outcome (P < 0.03).
