Article Synopsis
- The study evaluated the growth recovery in children with severe Hashimoto's hypothyroidism after starting thyroid hormone replacement therapy.
- A total of 29 children showed a significant height increase over 1 to 5 years of treatment, but final height didn't fully recover from the height loss at diagnosis.
- Growth hormone administration in the most severe cases may improve catch-up growth, indicating that HRT alone may not be enough for optimal recovery.
3D spatial priors for semi-supervised organ segmentation with deep convolutional neural networks.
Int J Comput Assist Radiol Surg
January 2022
Purpose: Fully Convolutional neural Networks (FCNs) are the most popular models for medical image segmentation. However, they do not explicitly integrate spatial organ positions, which can be crucial for proper labeling in challenging contexts.
Methods: In this work, we propose a method that combines a model representing prior probabilities of an organ position in 3D with visual FCN predictions by means of a generalized prior-driven prediction function.
Iterative confidence relabeling with deep ConvNets for organ segmentation with partial labels.
Comput Med Imaging Graph
July 2021
Training deep ConvNets requires large labeled datasets. However, collecting pixel-level labels for medical image segmentation is very expensive and requires a high level of expertise. In addition, most existing segmentation masks provided by clinical experts focus on specific anatomical structures.
