What are the most commonly used arteries for an angiographic exam?

The most commonly used arteries for an angiographic exam include the Common Femoral Artery (CFA), Axillary Artery, and Brachial Artery due to their accessibility and the significant information they provide regarding vascular conditions.

The CFA is particularly popular for access in lower extremity examinations, as it provides a central route for catheterization, allowing for thorough visualization of the arterial system. The Axillary Artery is also favored, especially for imaging upper extremities and providing access for procedures that may extend further proximally into the subclavian or carotid regions. The Brachial Artery serves as a convenient access point in cases where visualization of the upper limb or certain branches is needed.

These arteries are accessible and typically larger in diameter, which facilitates the introduction of catheters and instruments for diagnostic or interventional procedures. Their strategic locations within the body's vascular system make them ideal for various angiographic studies, offering a clear view of the arterial flow and any potential occlusions, lesions, or other pathologies.

In contrast, the other choices may involve arteries that are either not as commonly used for angiographic access or are less suitable due to their anatomical positioning or size. The Popliteal and Tibial arteries, for example,
