Application of Deep Learning for Detection of Nasal Bone Fracture on X-Ray Nasal Bone Lateral View.

Objectives: This study aimed to assess the efficacy of deep learning applications for detection of nasal bone fracture on X-ray nasal bone lateral view.

Methods: In this retrospective observational study, 2,968 X-ray nasal bone lateral views of trauma patients were collected from a radiology center, and randomly divided into training, validation, and test sets. Preprocessing included noise reduction by using the Gaussian filter and image resizing. Edge detection was performed using the Canny edge detector. Feature extraction was conducted using the gray-level co-occurrence matrix (GLCM), histogram of oriented gradients (HOG), and local binary pattern (LBP) techniques. Several machine learning algorithms namely CNN, VGG16, VGG19, MobileNet, Xception, ResNet50V2, and InceptionV3 were employed for classification of images into two classes of normal and fracture.

Results: The accuracy was the highest for VGG16 and Swin Transformer (79%) followed by ResNet50V2 and InceptionV3 (0.74), Xception (0.72) and MobileNet (0.71). The AUC was the highest for VGG16 (0.86) followed by VGG19 (0.84), MobileNet and Xception (0.83), and Swin Transformer (0.79).

Conclusions: The tested deep learning models were capable of detecting nasal bone fractures on X-ray nasal bone lateral views with high accuracy. VGG16 was the best model with successful results.
