How is aortography typically performed?

• A. Through an intravenous injection
• B. By introducing catheters into the aorta via the femoral artery
• C. Through ultrasound guidance
• D. Using percutaneous needle aspiration

Answer: (B)

Aortography is primarily performed by introducing catheters into the aorta via the femoral artery, which allows for direct access to the vascular system. This method is crucial because it enables the delivery of contrast material directly into the aorta, facilitating the imaging of the aorta and its branches through fluoroscopy or X-ray.

The procedure typically involves catheterization, where a catheter is navigated from the femoral artery, commonly located in the groin, up to the aorta. This approach provides a clear and comprehensive view of the aortic anatomy and any pathological conditions that may be present, such as aneurysms or blockages.

The other methods listed, such as intravenous injection, ultrasound guidance, and percutaneous needle aspiration, do not provide the same level of direct access or imaging detail for aortography as catheter-based techniques do. Therefore, using a catheter for aortography is the standard practice in interventional radiology.
