Abstract
Introduction: New imaging markers employing sophisticated models of tissue microstructure may lead to better understanding of neurobiological substrates in childhood arterial ischemic stroke. Methods: Four children with acute unilateral MCA territory ischemic stroke were retrospectively included [two males, age range 2 -16 years]. Parameters of two complementary diffusion modeling techniques: Neurite Orientation Dispersion and Density Imaging (NODDI), and Spherical Mean Technique (SMT) were estimated using two-shell diffusion data acquired at presentation ( b- values = 1000 and 3000 s/mm 2 ..
