AngiodynographyAngiodynography, like ultrasound, uses high frequency sound waves to generate computer images. This test is useful for documenting normal blood flow in the arteries and veins. The technician passes a hand held transducer, which looks like a microphone, across the surface of the skin, overlying the vessel in question. With the information gathered by the transducer, an image is generated (on a video screen) by computer, allowing the physician to determine whether blood flow is blocked in any way. Angiodynography is a relatively new technology. It is useful in a number of instances: 1. Checking blood flow in the carotid arteries. 2. Checking blood flow in upper and lower extremity arteries. 3. Evaluation of a possible blood clot in a leg vein. Angiodynography has no known risks and involves no exposure to radiation.
