Aneurysmal Versus “Benign” Perimesencephalic Subarachnoid Hemorrhage

Stroke: Vascular and Interventional Neurology
Background The rate of underlying ruptured aneurysms, complications, and their relevance to outcomes in “benign” perimesencephalic subarachnoid hemorrhage are not well known and underreported.

Physics-Informed Learning for Time-Resolved Angiographic Contrast Agent Concentration Reconstruction [PDF]

arXiv
Three-dimensional Digital Subtraction Angiography (3D-DSA) is a well-established X-ray-based technique for visualizing vascular anatomy. Recently, four-dimensional DSA (4D-DSA) reconstruction algorithms have been developed to enable the visualization of volumetric contrast flow dynamics through time-series of volumes. .

Toward an Integrated Decision Making Framework for Optimized Stroke Diagnosis with DSA and Treatment under Uncertainty [PDF]

arXiv
This study addresses the challenge of stroke diagnosis and treatment under uncertainty, a critical issue given the rapid progression and severe consequences of stroke conditions such as aneurysms, arteriovenous malformations (AVM), and occlusions. Current diagnostic methods, including Digital Subtraction Angiography (DSA), face limitations due to high ...

4DRGS: 4D Radiative Gaussian Splatting for Efficient 3D Vessel Reconstruction from Sparse-View Dynamic DSA Images [PDF]

arXiv
Reconstructing 3D vessel structures from sparse-view dynamic digital subtraction angiography (DSA) images enables accurate medical assessment while reducing radiation exposure. Existing methods often produce suboptimal results or require excessive computation time. In this work, we propose 4D radiative Gaussian splatting (4DRGS) to achieve high-quality
