Table 2. Analysis and comparison of AI quantitative parameters among different pathological subtypes (mean ± standard deviation).
| Parameters | AAH/AIS | MIA | IAC | H/χ 2 | P-value |
|---|---|---|---|---|---|
| 2D mean diameter (mm) | 8.54 ± 2.23 | 10.19 ± 2.68 | 14.98 ± 4.06 | 92.735 | <0.001 |
| 3D mean diameter (mm) | 8.44 ± 2.03 | 10.00 ± 2.39 | 14.60 ± 3.82 | 98.851 | <0.001 |
| Mean CT value (HU) | −631.75 ± 54.38 | −594.03 ± 63.87 | −516.42 ± 99.32 | 57.795 | <0.001 |
| Maximum CT value (HU) | −492.69 ± 135.90 | −405.39 ± 152.22 | −263.64 ± 169.65 | 37.344 | <0.001 |
| Volume (mm3) | 352.56 ± 257.92 | 588.39 ± 435.76 | 1807.72 ± 434.42 | 97.325 | 0.001 |
The pairwise comparison showed that the difference in quantitative parameters between two groups was statistically significant (for all, P<0.05 after adjustment by the Bonferroni method).
