Correction: Wang et al. Automated 3D Segmentation of the Aorta and Pulmonary Artery on Non-Contrast-Enhanced Chest Computed Tomography Images in Lung Cancer Patients. Diagnostics 2022, 12, 967

Errors occurred in the standard deviation of the Dice similarity coefficient (DSC) described in the original publication [1]. A correction of standard deviation value has been made to abstract, results (Section 3.3, second paragraph), discussion (Section 4, first paragraph and fifth paragraph), as well as Tables 2 and 3.

Text Correction

In abstract, 0.97 ± 0.66 should be corrected to 0.97 ± 0.007, and 0.93 ± 0.16 should be corrected to 0.93 ± 0.002.

In Section 3.3. Segmentation Model, in the second paragraph, 0.97 ± 0.66 should be corrected to 0.97 ± 0.007, and 0.93 ± 0.16 should be corrected to 0.93 ± 0.002.

In Section 4. Discussion, in the first paragraph, 0.97 ± 0.66 should be corrected to 0.97 ± 0.007, 0.91 ± 0.16 should be corrected to 0.91 ± 0.002, 0.93 ± 0.16 should be corrected to 0.93 ± 0.002. In the fifth paragraph, 0.92 ± 0.01 28 should be corrected to 0.92 ± 0.01.

Table Correction

In the third to fifth lines of Table 2, the DSC value of 0.97 ± 0.66, 0.87 ± 2.46, 0.91 ± 0.16, 0.93 ± 0.16, and 0.87 ± 0.04 should be corrected to 0.97 ± 0.007, 0.87 ± 0.025, 0.91 ± 0.002, 0.93 ± 0.002, and 0.87 ± 0.0004, respectively.

Aorta		Pulmonary Artery
Model	DSC	Model	DSC
1-AA	0.97 ± 0.007	1-PA	0.91 ± 0.002
		2-PA	0.93 ± 0.002
3D U-Net	0.87 ± 0.025	3D U-Net	0.87 ± 0.0004

1-AA, aorta segmentation model; 1-PA, one-channel pulmonary artery segmentation model by inputting non-contrast-enhanced image; 2-PA, two-channel model by inputting non-contrast-enhanced image and enhanced image; DSC, Dice similarity coefficient stage.

In the 15th and 21st lines of Table 3, the DSC value of 0.97 ± 0.66 should be corrected to 0.97 ± 0.007, and 0.93 ± 0.16 should be corrected to 0.93 ± 0.002.
