  • Note:—InterQ indicates interquartile; ROI, region of interest.

  • a PS values (milliliter × minute−1 × [100 g]−1) for patients with (n = 7) and without (n = 9) contrast extravasation. Subgroups are based on ROI location. Wilcoxon rank sum tests with a Bonferroni correction were used to compare data.

  • b Significantly different (P < .05) from all other subgroup mean PS values.
