Mean perilesional perfusion changes compared to homologous contralateral regions While a numerical difference in perilesional perfusion between the left ( M = 0.54, SD = 0.33) and right side ( M = 0.64, SD = 0.29) of the brain was still observed at follow up, this difference was only marginally significant, t (12) = 2.08, p = .06, q = .045, ns.
