What is Angiography?

Angiography is a medical imaging technique used to visualize blood vessels and organs, particularly arteries, veins, and heart chambers. It involves injecting a contrast dye into the bloodstream and then using X-rays, CT scans, or MRI scans to create detailed images of the blood vessels. Angiography is commonly used to diagnose and assess conditions such as atherosclerosis, aneurysms, blood clots, and tumors, and to guide interventional procedures such as angioplasty and stenting.
