Table 2:

PS data for 16 patients with ICH^a

Extravasation-Positive					Extravasation-Negative
	Spot Sign	PCL Lesions	Hematoma without Extravasation	Contralateral to Extravasation	Hematoma	Contralateral ROI
	lesions (9 foci)	(9 foci)		ROI	ROI
Mean PS	6.5 ± 1.6b	0.95 ± 0.39b	0.12 ± 0.39	0.26 ± 0.09	0.38 ± 0.26	0.09 ± 0.32
Median PS	6.69	0.87	0.15	0.29	0.42	0.07
InterQ range	5.31–7.36	0.67–0.98	0.06–0.34	0.25–0.31	0.14–0.59	0.03–0.40

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.
