DescriptionMRI perfusion in cerebral ischemia - (A) Improved collateral supply (B) Post-reperfusion hyperperfusion (C) Persistent hypoperfusion.jpg |
English: (A) MRA and Tmax in a patient with left MCA occlusion at 5 and 24 h. Despite persistent occlusion, the volume of Tmax > 6 s has reduced from 56 to 0 mL due to improved collateral supply. (B) Post-reperfusion hyperperfusion indicated by increased CBV (left), CBF (middle), and reduced Tmax (right) in a patient with recent reperfusion of left MCA occlusion. (C) MRI diffusion (pink) and perfusion (Tmax > 6 s, green) imaging 24 h post-stroke onset showing persistent hypoperfused tissue, which was contributing to the patient’s clinical deficit but had not developed diffusion restriction. |
