Magnetic resonance perfusion imaging directly shows ischemic areas and magnetic resonance diffusion imaging immediately shows its sequelae with high sensitivity. However, the prospective value of MRI for treatment is not yet determined. Although CT is considered relatively insensitive in acute ischemic stroke by some authors, all major clinical trials are using CT before the randomization of patients. This is explained by the wide availability and high practicability of … ER -
