UDCR: Unsupervised Aortic DSA/CTA Rigid Registration Using Deep Reinforcement Learning and Overlap Degree Calculation [PDF]

arXiv
The rigid registration of aortic Digital Subtraction Angiography (DSA) and Computed Tomography Angiography (CTA) can provide 3D anatomical details of the vasculature for the interventional surgical treatment of conditions such as aortic dissection and aortic aneurysms, holding significant value for clinical research. However, the current methods for 2D/

MoSt-DSA: Modeling Motion and Structural Interactions for Direct Multi-Frame Interpolation in DSA Images [PDF]

arXiv
Artificial intelligence has become a crucial tool for medical image analysis. As an advanced cerebral angiography technique, Digital Subtraction Angiography (DSA) poses a challenge where the radiation dose to humans is proportional to the image count. By reducing images and using AI interpolation instead, the radiation can be cut significantly. However,

Four simultaneous anterior cerebral artery aneurysms (three initially unsuspected) with surgical treatment

Radiology Case Reports, 2019
Distal anterior cerebral artery aneurysms are rare, comprising approximately 6% of all intracranial aneurysms. These aneurysms tend to be smaller in size, broad-based, associated with additional aneurysms and at arterial branching sites, which can make ...

Automated Registration of 3D Neurovascular Territory Atlas to 2D DSA for Targeted Quantitative Angiography Analysis [PDF]

arXiv
Subarachnoid hemorrhage (SAH), typically due to intracranial aneurysms, demands precise imaging for effective treatment. Digital Subtraction Angiography (DSA), despite being the gold standard, broadly visualizes cerebral blood flow, potentially masking key details in areas.

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. .

Changing Nature of Endoleak in a Patient of Superior Mesenteric Artery Aneurysm Treated with Endovascular Stent Graft

Journal of Clinical Interventional Radiology ISVIR
A man in his early thirties with complaints of abdominal pain for 1 week was diagnosed with a fusiform, partially thrombosed aneurysm of the superior mesenteric artery (SMA), which was treated with an endovascular stent graft.
