Comparison of Liver Volumes, Hepatic Lesion Volumes and Ratios with Clinical Severity in Patients of PA-SOS.

	Mild (n = 6)	Moderate (n = 10)	Severe (n = 9)	F value	P value
ROI liver (L)	1.824 ± 0.232	1.743 ± 0.552	1.645 ± 0.289	0.357	>0.05
ROI lesion (L)	0.681 ± 0.202	1.067 ± 0.381	1.015 ± 0.355	4.986	<0.05*
Ratio	0.3701 ± 0.0837	0.6070 ± 0.0742	0.7143 ± 0.0781	35.638	<0.05

^*The volume of ROI _lesion in patients with mild PA-SOS was significantly lower than that in patients with moderate and severe PA-SOS.
