T2 mapping can provide a route to monitor both iron changes in hemorrhage and water changes in ischemic stroke. Our aim is to investigate the value of T2 mapping from standard proton density and T2-weighted fast spin echo images for hemorrhagic and ischemic stroke. Rapid T2 maps using sequence modeling were reconstructed and compared with susceptibility and apparent diffusion coefficient for 13 hemorrhages and 14 ischemic stroke lesions respectively. Quantitative T2 is highly correlated with susceptibility for hemorrhage and diffusion for ischemic stroke, providing complementary measurements of water and iron changes.
