Table 3

Differences in medians of aortic dimensions measured by 2Decho and MRI.

	Median of ASI/diameter of aorta on 2Decho	Median of ASI/diameter of aorta on MRI	value
M1/D1	20.04 (14–30) mm/m^2	20.04 (12–30.5) mm/m^2	0.795
M2/D2	18.36 (12.65–24.67) mm/m^2	15.85 (10.15–22.59) mm/m^2	<0.001
M3/D3	18.85 (14–29.22) mm/m^2	17.3 (10.3–28) mm/m^2	0.001
M3/D4		16.23 (10.75–26.24) mm/m^2	<0.001
M4/D5	23 (16–40) mm	24.3 (14.9–45.7) mm	0.077
M4/D6		20.15 (14.5–28) mm	<0.001
M5/D7	17.5 (14–31) mm	18.1 (12–25.1) mm	0.591
M5/D8		17.8 (13–26.3) mm	0.574
M5/D9		16.4 (12.1–21.5) mm	0.003

The significance was calculated on the basis of the nonparametric Wilcoxon test for two related samples; min and max values are listed.
