Question

Quizplus · Accepted Answer

Ankle-brachial index (ABI) is a noninvasive test that measures the blood pressure in the ankles and compares it with the blood pressure in the arms at rest and after exercise. This test helps diagnose peripheral artery disease (PAD). Magnetic resonance angiography (MRA), positron emission tomography (PET), and CT angiography are imaging tests used to evaluate blood vessels, but they are not specifically used to diagnose PAD. The ankle dorsiflexion test is a physical exam maneuver not used for diagnostic purposes.
