FIG 2. Images from the case of patient 3, a 71-year-old man.
A, Three sections of isotropic trace diffusion images (5900/159/2) show abnormal increased signal in a contiguous 2-cm region of the left corona radiata, without any associated signal change in cortical regions.
B, Three time-to-peak perfusion maps (2199/82/35), obtained immediately after the diffusion images and at the same section positions, show slight hyperperfusion in the distribution of the abnormal diffusion signal shown in A. In addition, they show the otherwise unseen hypoperfusion throughout the left middle cerebral artery territory.
C, Representative sections from follow-up CT of the head, obtained 5 hours after the IV administration of thrombolytic therapy, show no infarct and no hemorrhage. The patient had no residual symptoms at the 48-hour follow-up examination
