  1. Hematoma volume measurements derived from pMRI exams were associated with impaired cognitive status and worse discharge functional outcome in unadjusted and adjusted multivariable linear regression models. Adjusted linear regression models included sex, race, and age.
  2. pMRI portable magnetic resonance imaging, T2W T2-weighted, FLAIR fluid-attenuated inversion recovery, NIHSS National Institutes of Health Stroke Scale, mRS Modified Rankin Scale.
