Successful thrombectomy of top-of-the-basilar artery occlusion - difficult to detect in clinical practice: A case report

Radiology Case Reports, 2023
Top-of-the-basilar artery occlusion frequently causes infarction of the midbrain, thalamus, and portions of the temporal and occipital lobes as the vascular supply of these regions comes from the posterior communicating and posterior cerebral arterial ...

A Joint Processing Strategy for Image Quality Improvement in 3D Digital Subtraction Angiography [PDF]

arXiv, 2023
Three-dimensional digital subtraction angiography (3D-DSA) is a widely adopted technique for clinical evaluation of contrast-enhanced vasculatures. The distribution of a contrast agent such as iodine is often estimated via temporal subtraction. Advancements in spectral imaging technologies such as photon counting detectors offer new opportunities to ...

Modified Dual-Energy Algorithm for Calcified Plaque Removal: Evaluation in Carotid Computed Tomography Angiography and Comparison With Digital Subtraction Angiography

Investigative Radiology, 2017
Objectives Computed tomography angiography (CTA) is a valuable tool for the assessment of carotid artery stenosis. However, blooming artifacts from calcified plaques might result in an overestimation of the stenosis grade.
