DECTA, Dual-energy computed tomographyic angiography; SECTA, Single-energy computed tomographic angiography.

Data are means ± 1 standard deviation.

^aValue was significantly different among three groups (p < 0.05), but there was no significant difference in pairwise comparisons.

^bValue was significantly greater (p < 0.017) than those with DECTA-40% and DECTA-80% groups.

^cValue was significantly greater (p < 0.017) than those with DECTA-40% group.
