In the aortic and liver ROIs,
SUVmax (mean±SE) were 2.04±0.29 and 2.50±0.28 in the low BMI group,
2.41±0.41 and 2.98±0.47 in the normal BMI group,
and 2.71±0.28 and 3.42±0.41 in high BMI group,
respectively.
SULPE were 1.72±0.27 and 2.10±0.27 in the low BMI group,
1.90±0.35 and 2.36±0.44 in the normal BMI group,
and 1.86±0.27 and 2.33±0.35 in the high BMI group,
respectively.
SUVS were 1.70±0.27 and 2.07±0.28 in the low BMI group,
1.82±0.30 and 2.25±0.36 in the normal BMI group,
and 1.76±0.26 and 2.23±0.35 in the high BMI group.
Table 2 shows the differences in aorta and liver SUVmax,
SULS,
and SULPE in each BMI group.
The value of SULPE wes significantly higher than that of SULS in total(aorta;p<0.001,
liver;p<0.001).
Although there is no significant difference between SULS and SULPE in the low BMI group(aorta;p=0.19,
liver;p=0.17), in the normal and high BMI groups we found a significant difference between SULs and SULPE. The similar trend of SULS and SULPE in liver was seen.
Meanwhile,
Figure 3 and 4 shows each SUVmax,
SULS,
and SULPE in aorta and liver of each BMI groups.
Evaluation each group,
no systematic dependence of SUVs on patient BMI was found in aorta and liver.
On the other hand,
in aortic SUVPE,
a significant difference was founded,
but relatively small between the low BMI and normal BMI groups.
As well as in hepatic SUVPE , low BMI group was a significantly lower than normal and high BMI group,
but relatively small.
However,
there is distinct difference in aortic and hepatic SUVmax value among 3 groups.
There was 27.5% difference in the aortic SUVmax between the low BMI group and high BMI group.
As well as it was reached 31.2% in the hepatic SUVmax.
By contrast,
the difference of SULPE is only about 10% of mean value in the aortic and hepatic VOIs.
