What is the purpose of using angiography in medical imaging?

The purpose of using angiography in medical imaging is to visualize vascular structures. Angiography is a specialized imaging technique that involves the use of contrast agents to highlight blood vessels, allowing for detailed observation of arteries, veins, and the vascular system as a whole. This technique is crucial for diagnosing and evaluating conditions related to blood flow, such as blockages, aneurysms, and other vascular abnormalities.

By using angiography, healthcare providers are able to obtain clear images that reveal the anatomy and potential issues within the vascular system, which is essential for planning medical or surgical interventions. This visualization is significantly more detailed than other imaging modalities that focus on different types of tissues or structures in the body, making angiography a specialized tool in the assessment of vascular health.
