SWI phase value (mean ± SD)−0.105 ± 0.080a−7.552 ± 0.024b0.029 ± 0.011

  • Note:—Statistical difference evaluated using Bonferroni post hoc pair-wise comparisons.

  • ↵a Significant difference compared with cavity (P = 0.003) and white matter (P < 0.001).

  • ↵b Significant difference compared with white matter (P = 0.001).
