Name one common imaging modality used in angiography.

Fluoroscopy is a common imaging modality used in angiography because it allows real-time visualization of the vascular system during diagnostic and therapeutic procedures. This capability is essential in angiography, where dynamic assessment of blood flow and vascular anomalies is required. Fluoroscopy utilizes X-ray technology to produce moving images, enabling clinicians to guide catheters and visualize the progression of contrast medium as it flows through blood vessels. This real-time imaging is crucial for ensuring the accuracy and effectiveness of interventional procedures such as stent placements, embolizations, and catheter-directed therapies.
