Gliomas are the most common primary brain malignancies, with different degrees of aggressiveness, variable prognosis and various heterogeneous histologic sub-regions, i.e., peritumoral edematous/invaded tissue, necrotic core, active non-enhancing core. This intrinsic heterogeneity is also portrayed in their radio-phenotype, as sub-regions depicted by varying intensity profiles disseminated across multi-parametric magnetic resonance imaging (mpMRI) scans, reflecting biological properties....
Medical image analysis and computer-assisted intervention problems are increasingly being addressed with deep-learning-based solutions. Established deep-learning platforms flexible but do not provide specific functionality for medical adapting them this domain of application requires substantial implementation effort. Consequently, there has been duplication effort incompatible infrastructure developed across many research groups. This work presents the open-source NiftyNet platform deep...
Computational pathology is revolutionizing the field of by integrating advanced computer vision and machine learning technologies into diagnostic workflows. It offers unprecedented opportunities for improved efficiency in treatment decisions allowing pathologists to achieve higher precision objectivity disease classification, tumor microenvironment description identification new biomarkers. However, potential computational personalized medicine comes with significant challenges, particularly...
Real-time tool segmentation from endoscopic videos is an essential part of many computer-assisted robotic surgical systems and critical importance in data science. We propose two novel deep learning architectures for automatic non-rigid instruments. Both methods take advantage automated deep-learning-based multi-scale feature extraction while trying to maintain accurate quality at all resolutions. The proposed encode the constraint inside network architecture. first architecture enforces it...
In-utero fetal MRI is emerging as an important tool in the diagnosis and analysis of developing human brain. Automatic segmentation brain a vital step quantitative prenatal neurodevelopment both research clinical context. However, manual cerebral structures time-consuming prone to error inter-observer variability. Therefore, we organized Fetal Tissue Annotation (FeTA) Challenge 2021 order encourage development automatic algorithms on international level. The challenge utilized FeTA Dataset,...
Deep learning models for medical image segmentation can fail unexpectedly and spectacularly pathological cases images acquired at different centers than training images, with labeling errors that violate expert knowledge. Such undermine the trustworthiness of deep segmentation. Mechanisms detecting correcting such failures are essential safely translating this technology into clinics likely to be a requirement future regulations on artificial intelligence (AI). In work, we propose...
Spina bifida aperta (SBA) is a birth defect associated with severe anatomical changes in the developing fetal brain. Brain magnetic resonance imaging (MRI) atlases are popular tools for studying neuropathology brain anatomy, but previous MRI have focused on normal We aimed to develop spatio-temporal atlas SBA.
In fetal Magnetic Resonance Imaging, Super Resolution Reconstruction (SRR) algorithms are becoming popular tools to obtain high-resolution 3D volume reconstructions from low-resolution stacks of 2D slices, acquired at different orientations. To be effective, these often require accurate segmentation the region interest, such as brain in suspected pathological cases. case Spina Bifida, Ebner, Wang et al. (NeuroImage, 2020) combined their SRR algorithm with a 2-step pipeline (2D localisation...
A retrospective study was performed to the effect of fetal surgery on brain development measured by MRI in fetuses with myelomeningocele (MMC).
Congenital diaphragmatic hernia is associated with high mortality and morbidity, including evidence suggesting neurodevelopmental comorbidities after birth. The aim of this study was to document longitudinal changes in brain biometry the cortical folding pattern fetuses congenital compared healthy fetuses.
Recent research on COVID-19 suggests that CT imaging provides useful information to assess disease progression and assist diagnosis, in addition help understanding the disease.
