2024年11月12日 · This paper presents a comprehensive dataset comprising high-resolution CTA images of 99 patients with 105 MCA aneurysms and 44 normal healthy controls, along with their respective clinical data...

What is computed tomography (CT) angiography? CT angiography is a type of medical test that combines a CT scan with an injection of a special dye to produce pictures of blood vessels and tissues in a part of your body. The dye is injected through an intravenous (IV) line placed in …

Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography —the visualization of arteries and veins —throughout the human body.

2024年11月13日 · This dataset focuses on intracranial aneurysm research, providing high-resolution CTA images along with related clinical, morphological, and hemodynamic parameters for 44 healthy control subjects (see controls.rar) and …

2024年7月23日 · CT angiography of the cerebral arteries, also known as a CTA carotids or an arch to vertex angiogram, is a non-invasive technique that allows visualization of the internal and external carotid arteries and vertebral arteries and can include just the intracranial compartment or also extend down to the arch of the aorta.

This dataset contains about 1000 3D CTA images, which is considerably larger than the existing public datasets. On the other hand, we also propose a benchmark based on the proposed dataset, in which we have not only implemented several typical existing methods but also proposed a strong baseline method.

2023年10月1日 · Computed tomography angiography (CTA) is one of the widely used noninvasive imaging modalities in coronary artery diagnosis due to its superior image resolution. Clinically, segmentation of coronary arteries is essential for the diagnosis and quantification of coronary artery disease.

This is an illustrative case of a normal CT angiography obtained after IV contrast administration. Please refer on the article normal brain imaging examples for more examples like this one. UQ Radiologic Anatomy 1. Brain 1.07 Intracranial Arteries.

2020年11月30日 · Therefore, we collected 1177 digital subtraction head bone-removal CTA images, which were based on a section-by-section subtraction to subtract nonenhanced from enhanced CT data to facilitate the...

CT angiography uses a CT scanner to produce detailed images of both blood vessels and tissues in various parts of the body. During the exam, contrast material is injected through a small catheter placed in a vein of the arm. A radiologic technologist will capture high-resolution CT images while the contrast material flows through the blood vessels.
