This paper investigates the problem of skull stripping and proposes complementary segmentation networks (CompNets) to accurately extract the brain from T1-weighted MRI scans, for both normal and pathological brain images, resulting in the state of the art performance under the two-fold cross-validation setting.
A new log-cosh dice loss function is introduced and it is showcased that certain loss functions perform well across all data-sets and can be taken as a good baseline choice in unknown data distribution scenarios.
To predict the Alzheimer's disease with a deep 3D convolutional neural network (3D-CNN), which can learn generic features capturing AD biomarkers and adapt to different domain datasets, which has been validated on the CADDementia dataset.
This work proposes a novel approach based on Convolutional Neural Networks to automatically perform the brain extraction obtaining cutting-edge performance in the NFBS public database and focuses on the efficient training of the neural network designing an effective data augmentation pipeline.
Ability of the 3D-CNN to generalize the features learnt and adapt to other domains have been validated on the ADNI dataset and experiments on the CADDementia MRI dataset with no skull-stripping preprocessing have shown it outperforms several conventional classifiers by accuracy.
An Anatomical Context-Encoding Network (ACEnet) is developed to incorporate 3D spatial and anatomical contexts in 2D convolutional neural networks (CNNs) for efficient and accurate segmentation of brain structures from MR scans.
SynthSR turns clinical scans of different resolution and contrast into 1 mm MPRAGEs and enables segmentation, registration, etc with existing software (e.g. FreeSurfer) Code.
It is suggested that image intensity normalization approaches do not contribute to model accuracy because of the reduction of signal variance with image standardization, and that the contribution of skull-stripping in data preprocessing is almost negligible if measured in terms of estimated tumor volume.
The use of silver standard masks reduced the cost of manual annotation, decreased inter-intra-rater variability, and avoided CNN segmentation super-specialization towards one specific manual annotation guideline that can occur when gold standard masks are used.
MedicDeepLabv3+, a convolutional neural network that is the first completely automatic method to segment cerebral hemispheres in magnetic resonance (MR) volumes of rats with ischemic lesions, yielded excellent results in multiple scenarios, demonstrating its capability to reduce human workload in rat neuroimaging studies.
Adding a benchmark result helps the community track progress.
