- Fig 1.
Acute images for 3 patients with decreasing infarct volumes. Patient 1 shows a delayed AAT region (hyperintensity) in the affected hemisphere, where CBF is reduced (hypointensity). Patient 12 shows reduced CBF in the affected hemisphere and delayed AAT, while maps for Patient 9 have normal findings. Abnormal CBF and AAT regions are outlined in red.
- Fig 2.
AAT hemispheric asymmetry index is displayed as a bar plot for each patient. Control cohort data are more symmetric about zero with less variance. Patient data are significantly different from those of controls (P < .048). Light gray indicates DWI-positive; dark gray, DWI-negative; diamond datum, control participant.
