Table 2:

Reproducible Radiomic Features per Radiomic Feature Category for Changes in One Single Technical Parameter While the Other Technical Parameters Were Kept Constant

Feature	All Radiomic Features (n = 106)	Intensity Radiomic Features (n = 17)	Shape Radiomic Features (n = 16)	Texture Radiomic Features (n = 73)	Mean Attenuation*	Maximum Axial Diameter*	Volume*
Radiation dose level	22 (20.8)	2 (11.8)	16 (100)	4 (5.5)	0	1 (100)	1 (100)
Reconstruction algorithm	42 (39.6)	9 (52.9)	16 (100)	17 (23.3)	1 (100)	1 (100)	1 (100)
Reconstruction kernel	56 (52.8)	15 (88.2)	16 (100)	25 (34.2)	1 (100)	1 (100)	1 (100)
Section thickness	13 (12.3)	1 (5.9)	8 (50)	4 (5.5)	0	1 (100)	1 (100)

Note.—Categorical variables are summarized as frequencies and percentages (in parentheses) from total of radiomic features. Reproducible radiomic features were defined as those with R² > 0.95.
