Table 2. Diastolic Function Parameters for Cardiac CT and 2D Echocardiography.

	Cardiac CT†				Echocardiography
	Dataset A (n = 46)	Dataset B (n = 44)	Dataset C (n = 46)	Dataset D (n = 44)
E	67.98 ± 23.36 (r = 0.67, p < 0.01)	56.31 ± 23.43 (r = 0.64, p < 0.01)	61.09 ± 20.59 (r = 0.70, p < 0.01)	49.09 ± 16.64 (r = 0.70, p < 0.01)	64.85 ± 16.58
E’	7.23 ± 3.22 (r = 0.70, p < 0.01)	5.08 ± 2.10 (r = 0.52, p < 0.01)	6.79 ± 2.90 (r = 0.61, p < 0.01)	4.87 ± 2.12 (r = 0.54, p < 0.01)	6.03 ± 2.12
E / E’*	10.64 ± 4.29 (r = 0.77, p < 0.01)	11.92 ± 4.50 (r = 0.56, p < 0.01)	9.90 ± 3.90 (r = 0.47, p < 0.01)	11.16 ± 4.00 (r = 0.36, p < 0.05)	11.39 ± 2.90

Data are expressed as mean ± standard deviation (correlation coefficient [r] between CT and echocardiography). E and E′ stands for transmitral velocity (cm/s) and mitral septal velocity (cm/s), respectively. ^*Correlation between echocardiography and CT dataset A for E / E′ is stronger (p < 0.05) than those between echocardiography and dataset B, C, or D. ^†Images are reconstructed with slice thickness/increment of 0.9/0.9 mm at 5% RR-interval in dataset A, with 0.9/0.9 mm at 10% in dataset B, with 3/3 mm at 5% in dataset C, and finally 3/3 mm at 10% in dataset D.
