ABSTRACT

Objective:

To explore the effect of fully automatic image segmentation of adenoid and nasopharyngeal airway by deep learning model based on U-Net network.

Methods:

From March 2021 to March 2022, 240 children underwent cone beam computed tomography(CBCT) in the Department of Otolaryngology, Head and Neck Surgery, General Hospital of Shenzhen University. 52 of them were selected for manual labeling of nasopharynx airway and adenoid, and then were trained and verified by the deep learning model. After applying the model to the remaining data, compare the differences between conventional two-dimensional indicators and deep learning three-dimensional indicators in 240 datasets.

Results:

For the 52 cases of modeling and training data sets, there was no significant difference between the prediction results of deep learning and the manual labeling results of doctors(P>0.05). The model evaluation index of nasopharyngeal airway volume Mean Intersection over Union(MIOU) s (86.32±0.54)%; Dice Similarity Coefficient(DSC) (92.91±0.23)%; Accuracy (95.92±0.25)%; Precision (91.93±0.14)%; and the model evaluation index of Adenoid volume MIOU (86.28±0.61)%; DSC (92.88±0.17)%; Accuracy (95.90±0.29)%; Precision (92.30±0.23)%. There was a positive correlation between the two-dimensional index A/N and the three-dimensional index AV/(AV+NAV) in 240 children of different age groups(P<0.05), and the correlation coefficient of 9-13 years old was 0.74.

Conclusion:

The deep learning model based on U-Net network has a good effect on the automatic image segmentation of adenoid and nasopharynx airway, and has high application value. The model has a certain generalization ability.
