Note:—Correlation analysis of tissue specimens is stratified into enhancing or nonenhancing groups (N = 36). The correlation between track density and vascular hyperplasia and cellular proliferation was not examined within nonenhancing regions, as these are not typical biological features within this region.⁹

^*P value <.05 is considered statistically significant.
