Note.—ICA/MCA indicates occlusion of the internal carotid artery with accompanying occlusion of the middle cerebral artery; CTO, occlusion of the intracranial ICA bifurcation (carotid T occlusion), MCA occlusion of the trunk or trifurcation (M1/2), and MCA branch occlusion (segments M3 and M4); rt-PA, recombinant tissue plasminogen activator; L0, lesion at day 0 defined by a reduced apparent diffusion coefficient (ADC); LG1 and LG7, lesion growth on T2-weighted images until day 1 and 7; and ST7 = surviving tissue at day 7 (tissue with initially reduced cerebral blood flow but without T2 prolongation at day 7). Volumes are median and range (min–max).
