Spatiotemporal Dynamic Simulation of Acute Perfusion/Diffusion Ischemic Stroke Lesions Evolution: A Pilot Study Derived from Longitudinal MR Patient Data

MTT-DWI mismatch at first acquisition acute timepoint 𝑡₁. Top row: MTT-DWI mismatch area in blue visualised on 2D MR axial slices. Bottom row: the 3D reconstruction of MTT and DWI surfaces and their corresponding mismatch spatially defined as the “output space” produced when taking the diffusion volume out of the perfusion one, outlined in blue.
