Large ischemic penumbra with small core infarct in a 73Â year-old with acute stroke. MRA shows acute M1 segment MCA vessel cutoff (arrow, a). Blooming artifact localizes to the occlusive thrombus on the GRE image (arrow, b). Apparent diffusion coefficient (a, d, c) map (c, d) demonstrating a small region of core infarct (arrowhead). CBV maps from the PCT show no region of decrease to suggest a large core infarct (e, f). Ischemic penumbra comprises the majority of the left MCA territory on the Tmax maps (g, h)
