A semi-automated segmentation method for detection of pulmonary embolism in True-FISP MRI sequences [PDF]
arXiv, 2017 Pulmonary embolism (PE) is a highly mortal disease, currently assessed by pulmonary CT angiography. True-FISP MRI has emerged as an innocuous alternative that does not hold many of the limitations of x-ray imaging. However, True-FISP MRI is very sensitive to turbulent blood flow, generating artifacts that may resemble fake clots in the pulmonary ...

Label up: Learning Pulmonary Embolism Segmentation from Image Level Annotation through Model Explainability [PDF]
arXivPulmonary Embolisms (PE) are a leading cause of cardiovascular death. Computed tomographic pulmonary angiography (CTPA) stands as the gold standard for diagnosing pulmonary embolisms (PE) and there has been a lot of interest in developing AI-based models for assisting in PE diagnosis. Performance of these algorithms has been hindered by the scarcity of

Pi-PE: A Pipeline for Pulmonary Embolism Detection using Sparsely Annotated 3D CT Images [PDF]
arXiv, 2019 Pulmonary embolisms (PE) are known to be one of the leading causes for cardiac-related mortality. Due to inherent variabilities in how PE manifests and the cumbersome nature of manual diagnosis, there is growing interest in leveraging AI tools for detecting PE.

Nonlinear dynamics of air invasion in one-dimensional compliant fluid networks [PDF]
arXivVascular networks exhibit a remarkable diversity of architectures and transport mechanisms across biological systems. Inspired by embolism propagation in plant xylem - where air invades water-filled conduits under negative pressure - we study air penetration in compliant one-dimensional hydrodynamic networks experiencing mass loss by pervaporation ...

Channel deformations during elastocapillary spreading of gaseous embolisms in biomimetic leaves [PDF]
arXivThe nucleation and/or spreading of bubbles in water under tension (due to water evaporation) can be problematic for most plants along the ascending sap network from root to leaves, named xylem. Due to global warming, trees facing drought conditions are particularly threatened by the formation of such air embolisms, which spreads intermittently and ...

1D Thermoembolization Model Using CT Imaging Data for Porcine Liver [PDF]
arXivObjective: Innovative therapies such as thermoembolization are expected to play an important role in improvising care for patients with diseases such as hepatocellular carcinoma. Thermoembolization is a minimally invasive strategy that combines thermal ablation and embolization in a single procedure.
