Spatial distribution parameters show strong ability to detect spinal cord injury and more limited ability to detect injury severity. (A) Umbra flow showed significant decrease from pre- to post-injury, and trends of decreasing flow as severity increased. (E) Injury extent showed significant increase from the mild to severe injuries. (B,F) Flow in the penumbra, both rostrally (B) and caudally (F), was significantly elevated as compared to pre-injury values. However, only the rostral penumbra had significant differences between injury types. (C,G) The distal flow was unchanged from pre-to post-injury in both directions. (D,H) The penumbra prominence showed greatest separation between both pre- and post-injury comparisons and between injury severities. Again, however, only the rostral penumbra (D) showed significant differences between injury types. Significance of differences between pre- to post-injury reported from two-way repeated measures ANOVA. Significance of differences between injury severities calculated using Šidák multiple comparisons. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, ns not statistically significant.
