Figure 4.
Tracer enrichment in different intradural locations. Tracer (gadobutrol) enrichment over time within (A) PSD (n = 47), (B) PSDe (n = 27) and (C) within De into diploe of skull bone marrow in distance from PSD (n = 12). The plots show tracer enrichment as a percentage change in normalized T1-BB signal units. The signal change, indicative of tracer enrichment, was highly significant for all locations (linear mixed model analysis; *P < 0.05, **P < 0.01, ***P < 0.001), with peak at 24 h. Trend plots presented by mean and error bars as standard errors.
