CTangiografiasta

CTangiografia, also known as CT angiography or CTA, is a medical imaging technique that uses computed tomography (CT) scanning to visualize blood vessels. This diagnostic procedure combines CT scanning with the injection of a contrast dye into the bloodstream. The contrast material enhances the visibility of the arteries and veins, allowing detailed imaging of their structure and any abnormalities.

The process typically involves a CT scanner, which is a type of X-ray machine that takes multiple cross-sectional images of the body. A contrast agent, usually iodine-based, is administered intravenously, often through a catheter inserted into a vein. As the contrast material circulates through the blood vessels, the CT scanner acquires images. Sophisticated software then processes these images to create three-dimensional representations of the vascular system.

CTangiografia is a valuable tool for diagnosing a wide range of vascular conditions. It is commonly used to detect aneurysms, which are bulges in blood vessel walls, and dissections, which are tears in the vessel lining. It is also effective in identifying blockages or narrowing of arteries, known as stenosis, which can lead to reduced blood flow and conditions like stroke or peripheral artery disease. Furthermore, CTA can be used to evaluate blood clots, assess trauma to blood vessels, and plan surgical or interventional procedures. The procedure is generally quick and non-invasive, though it does involve exposure to radiation and the potential for allergic reactions to the contrast dye.
