Angiogram or angiography

Angiography is a diagnostic and interventional imaging technique used to assess the patency and condition of blood vessels. It involves the injection of a radiopaque contrast medium into the vascular system, followed by X-ray, fluoroscopy, CT, or MRI imaging. This allows for real-time visualization of the vasculature, helping to diagnose conditions like atherosclerotic plaques, aneurysms, and vascular malformations.

Coronary angiography remains a gold standard for identifying coronary artery disease, often leading directly to interventional procedures such as stenting or angioplasty. With advancements like digital subtraction angiography (DSA) and the use of non-invasive CT angiography (CTA), the field has expanded its precision and scope, reducing the need for more invasive diagnostic methods.
