FIG 1. MR imaging 2 hours after the onset of stroke.

A and D, Acute MR imaging with two representative sections of DW imaging revealing a small lesion in the subcortical white matter (A, arrow), suggesting hemodynamic infarction.

B and E, Acute MR imaging with the same sections of TTP, demonstrating a perfusion delay in almost the entire right MCA territory and in both ACA territories.

C and F, Acute MR imaging with the same sections of CBF showing a decrease of cerebral blood flow in almost the entire right MCA territory and in both ACA territories, matching the TTP results.
