Cover Story: Evaluation of the 3D bone morphology of the glenohumeral joint is crucial for medicine. Zero echo time (ZTE) magnetic resonance imaging (MRI) provides excellent bone contrast and can potentially be used in the place of computed tomography. Segmentation of the shoulder bone anatomy is helpful for unobstructed assessment and measurements. We compared two popular convolutional deep learning models of DeepLab and U-Net for automated segmentation of ZTE MRI of human shoulders. While both models were satisfactory, U-Net slightly over-estimated, while DeepLab under-estimated the segmented area compared to the ground truth. The Dice score was significantly higher for U-Net than DeepLab for the humeral segmentation. We also implemented the U-Net model on an MRI console for push-button processing. This study has the potential to improve shoulder MR evaluation hindered by manual post-processing. View this paper
