Table 4. Diagnostic Performance of Cardiac CT in Comparison with 2D Echocardiography.

Diagnostic Performance*	Dataset A†	Dataset B	Dataset C	Dataset D
Sensitivity (%)	64.3	57.1	21.4	42.9
Specificity (%)	96.9	78.1	87.5	71.9
Positive predictive value (PPV) (%)	90.0	53.3	42.9	40.0
Negative predictive value (NPV) (%)	86.1	80.7	71.8	74.2
Accuracy (%)	87.0	71.7	67.4	63.0

^*Sensitivity of dataset A was higher than that of B, and specificity of A was higher than those of B and D (p < 0.05). PPV of dataset A was higher than that of D, and accuracy of dataset A is higher than those of C and D (p < 0.05). Otherwise, no significant difference was noted in diagnostic performances between 4 reconstruction parameters. p value by McNemar for sensitivity, specificity, and accuracy. p value by Fisher's exact test for PPV and NPV, ^†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.
