Abstract

In the article, “Assessment of Cerebral Blood Flow and CO2 Reactivity After Controlled Cortical Impact By Perfusion Magnetic Resonance Imaging Using Arterial Spin-Labeling in Rats,” by Michael L. Forbes et al., which appeared in the Journal of Cerebral Blood Flow and Metabolism (1997;17:865-874), the legends for Figures 2 and 4 were incorrectly shown. The figures with their correct legends appear below.

FIG. 2.

Mean CBF from regions of interest (ROI) within the parietal cortex in control rats [□, n = 5] and in rats 24 hours after either sham [▪, n = 5] or traumatic brain injury (TBI) [▪, n = 4] during normocarbia. (A) Cortical ROI, *P = 0.01, left versus right within TBI group. (B) Contusion-enriched ROI enhancing the contribution of the contusion, *P = 0.032 left versus right within sham. **P = 0.003 left versus right within TBI group.

FIG. 4.

Mean CBF from ROI within the parietal cortex in control rats [□, n = 5] and in rats 24 hours after either sham [▪, n = 5] or TBI [▪, n = 4] before and during hypocarbia. (A) Cortical ROI. (B) Contusion-enriched ROI (*P < 0.05, hypocarbia versus normocarbia within groups).
