Which process is used to demonstrate vascular abnormalities using fluoroscopy?

Angiography is the specialized imaging technique used to visualize vascular abnormalities through fluoroscopy. This procedure involves the injection of a contrast agent directly into the blood vessels, which then allows the blood vessels to be clearly outlined on the fluoroscopic images. It is particularly useful for diagnosing conditions such as blockages, aneurysms, or malformations in the vascular system.

The use of fluoroscopy in angiography provides real-time imaging, which is beneficial for both diagnostic purposes and interventional procedures, such as stent placements and embolizations. This dynamic imaging capability helps clinicians assess the vascular structure and function accurately, ensuring that appropriate treatment plans can be developed based on the observed abnormalities.

In contrast to angiography, techniques like CT scans and X-rays do not specifically target vascular abnormalities for real-time imaging, and while ultrasound can evaluate some vascular conditions, it does not utilize fluoroscopy. Therefore, angiography is the correct choice for demonstrating vascular abnormalities with this imaging method.
