Mayo Clinic doctors trained in blood vessel conditions (vascular specialists), doctors trained in imaging (radiologists) and others diagnose your condition.

Doctors usually find popliteal artery aneurysms during routine physical examinations or identify them during imaging tests such as ultrasounds or computerized tomography (CT) scans. Popliteal artery aneurysms often occur without symptoms.

Doctors may order several tests to diagnose your condition, including:

  • Ultrasound. An ultrasound uses sound waves to produce detailed images of your blood vessels. An ultrasound helps doctors determine the size of the aneurysm and blood flow through the popliteal artery.
  • Duplex ultrasound. Duplex ultrasound is a special ultrasound that gives detailed information about the size of the aneurysm, potential blood clots that may have formed in the popliteal artery and blood flow through the popliteal artery. Doctors often use ultrasound and duplex ultrasound to diagnose people with popliteal artery aneurysms, and order other tests if needed.

    Doctors may also conduct duplex ultrasound to check for aneurysms in other areas of your body, if a popliteal artery aneurysm has been detected.

  • Computerized tomography (CT). A CT scan uses a series of X-rays to create detailed images of the blood vessels in your leg. Sometimes doctors may inject a dye into your blood vessels to show the blood flow (CT angiography).
  • Magnetic resonance imaging (MRI). An MRI uses powerful magnets and radio waves to create detailed images of your body's soft tissues. Sometimes doctors may inject a dye into your blood vessels to show the blood flow (magnetic resonance angiography).
